PREFACE
The Atomic Energy Commission (AEC) has used the Nevada Test Site (NTS) since
January 1951 as an area for conducting nuclear detonations, nuclear rocket/
engine development, nuclear medicine studies, and miscellaneous nuclear and
non-nuclear experiments. Except during the testing moratorium from October 30,
1958, to September 1, 1961, atmospheric nuclear tests were conducted period-
ically from 1951 through July 17, 1962. Since July 17, 1962, in accordance
with the limited test ban treaty, all nuclear detonations have been conducted
underground with the expectation of containment except for five nuclear earth-
cratering experiments conducted under the Plowshare program.
Under the U. S. Public Health Service (PHS) from 1959 through 1972, and since
1972, under the U. S. Environmental Protection Agency (EPA), facilities have
been maintained in Las Vegas, Nevada, for the purpose of providing an Off-
Site Radiological Surveillance-Program for the AEC. Prior to that time, sur-
veillance was performed by the Los Alamos Scientific Laboratory and by U. S.
Army personnel. Although off-site surveillance has been provided by the Las
Vegas facility for nuclear experiments at places other than the NTS, the
primary effort has been centered around the NTS.
The objective of the Program from the beginning has been to measure levels and
trends of radioactivity in the off-site environment surrounding testing areas
to assure that the testing is in compliance with existing radiation protec-
tion standards. To assess off-site radiation levels, routine sampling net-
works for milk, water, and air are maintained along with a dosimetry network
and special samplings of food crops and soil, etc.
In general, analytical results showing radioactivity levels above naturally
occurring levels have been published in reports covering a test series or
test project. Beginning in CY 1959 for reactor tests and in CY 1962 for
weapons tests, surveillance data for each individual test which released ra-
dioactivity off-site were reported separately. Commencing in January 1964
and continuing through December 1970, these individual reports for nuclear
-------
tests were summarized and reported every six months with, the analytical re-
sults for all routine or special milk samples.
In CY 1971, the AEG implemented a requirement (AEC Manual, Chapter 0513)
for a more comprehensive radiological monitoring report from each of the
several contractors or agencies involved in major nuclear activities. The
compilation of these various reports since that time and their entry into
the general literature serve the purpose of providing a single source of
information concerning on-going environmental impact data from AEC spon-
sored activities. To provide more rapid dissemination of data, the monthly
reports of analytical results of all air data collected since July 1971 and
all milk and water samples collected since January 1972 are submitted to
the appropriate state health departments involved and published in Radiation
Data and Reports.
Since 1962, aircraft have also been used during nuclear tests to provide
rapid monitoring and sampling for releases of radioactivity. Early aircraft
monitoring data were used to position mobile radiation monitors, and the re-
sults of cloud sampling were used to quantitate the inventories of the radio-
nuclides released. Beginning with CY 1971, all monitoring and sampling re-
sults of aircraft were reported in an effluent monitoring data report in
accordance with AEC Manual, Chapter 0513.

INTRODUCTION
Under a Memorandum of Understanding No. AT(26-l)-539 with the U. S. Atomic
Energy Commission (AEC), the U. S. Environmental Protection Agency (EPA),
National Environmental Research Center-Las Vegas (NERC-LV), continued a pro-
gram of routine and special radiological surveillance of various media in
the environment surrounding the Nevada Test Site (NTS) and other sites des-
ignated by the AEC during 1972. This report, prepared in accordance with
the AEC Manual, Chapter 0513, contains summaries of NERC-LV sampling method-
ologies, analytical procedures, and the results of all environmental samples
collected in support of AEC nuclear testing activities. Where applicable,
sampling results are also compared to appropriate guides for external and in-
ternal exposures to ionizing radiation. In addition, a brief summary of per-
tinent ecological and demographical features of the NTS and the NTS environs
is presented for background information.
Nevada Test Site
The major programs conducted at the NTS are nuclear weapons development,
proof-testing and weapons safety, testing for peaceful uses of nuclear ex-
plosives (Project Plowshare), nuclear rocket development (Project Rover),
basic high-energy nuclear physics research, and seismic studies (Vela-Uniform)
At the Nuclear Rocket Development Station (NRDS), located in the southwest
corner at the NTS, a program of testing reactors of various designs and pur-
poses has been conducted over the past 13 years. The major programs were
oriented toward design feasibility and subsequent development of a nuclear
rocket engine. The last tests of these engines were conducted in 1969. No
reactors were tested in 1970 and 1971. During 1972, a small reactor called
the Nuclear Furnace-1 was tested seven times during May, June, and July.
In addition, underground nuclear testing was conducted at the NTS during
1972. No radioactivity was detected at ground level beyond the boundaries
of the NTS following any of these nuclear events or the Nuclear Furnace-1
test series.
-------
Site Location
The Nevada Test Site (Figures 1 and 2) is located in Nye County, Ne-
vada, with its southeast corner about 65 miles northwest of Nevada's
largest city, Las Vegas. The NTS has an area of about 1,350 square
miles and varies from 25-35 miles in width (east-west) and from 40-55
miles in length (north-south). This area consists of large basins or
flats about 3,000-4,000 feet above Mean Sea Level (MSL) surrounded by
mountain ranges 6,000-7,000 feet MSL.
The NTS is almost surrounded by an exclusion area collectively named
the Nellis Air Force Range. The Range, particularly to the north and
east, provides a buffer zone between the test areas and public lands.
This buffer zone varies from 15 to 65 miles between the test area and
land that is open to the public. Depending upon wind speed and di-
rection, this provides a delay of 1/2 hour to more than six hours be-
fore any release of airborne radioactivity crossing the NTS boundary
passes over public lands.
Ecology and Climate
The ecology of the site varies considerably. The southern portion is
true desert of the Mojave type. The remainder of the NTS is mixed
grasslands with Pinon-Juniper at the higher levels. This type of eco-
system is broadly referred to as Basin-Range Desert. The dry lakes
found in the lower portion of the basins are highly mineralized silts
which do not support any vegetation. The area supports a number of
small mammals and reptiles with deer occasionally seen on the plateaus.*
The climate of the NTS is also variable, primarily due to altitude and
the rugged terrain. Generally the climate is referred to as Continental
For an excellent bibliography of appropriate references, see Schultz, Vincent,
"References on Nevada Test Site Ecological Research," Great Basin Naturalist,
26[3-4]: December 31, 1966.
-------
Arid. Average annual precipitation ranges from, about four inches at
the 3,000 foot altitude to around 10 inches on the plateaus. During
the winter months , the plateaus may be snow-covered for periods of sev-
eral days or weeks, while snow is uncommon on the flats. Temperatures
vary with elevation, slope, and local air currents. The average daily
high (low) temperatures at low altitude is around 50° (25°) F in Janu-
ary and 95° (55°) F in July, with extremes of 110° and -15°. Corre-
sponding temperatures on the plateaus are 35° (25°) F in January and
80° (65°) F in July with extremes of 100° and -20°. Temperatures as
low as *300 and higher than 115° have been observed at the NTS.
The prevailing wind direction, as measured on a 100-foot tower at the
Yucca observation station, is predominately northerly except for the
months of May through August when winds from the south-southwest pre-
dominate. Because of the prevalent mountain-valley winds in the basins,
south to southwest winds predominate during daylight hours during most
months . During the winter months southerly winds have only a slight
edge over northerly winds for a few hours during the warmest part of
the day. These wind patterns may be quite different at other locations
on the NTS because of local terrain effects and differences in eleva-
Geology and Hydrology
Geological and hydrological studies of the NTS have been in progress by
the U. S. Geological Survey and various other institutions since 1956,
when underground nuclear explosions were first contemplated. Because
of this continuing effort, including subsurface studies of numerous bore-
holes, the surface and underground geological and hydrological character-
istics for much of the NTS are known in considerable detail. This is
particularly true for those areas in which underground experiments are
conducted. A comprehensive summary of the geology and hydrology of the
NTS was published in 1968 as Memoir 110 by the Geological Society of
America, entitled, "Nevada Test Site."
-------
The lithological features of the NTS may be simply described as being
of three major rock units—(1) basement rock of Paleozoic age overlain
by (2) volcanic tuffs of Tertiary age, which in the valleys are over-
lain by (3) alluvium as much as 3,000 feet thick. Underground nuclear
tests, except for a very few special-purpose tests, are conducted in
either volcanic tuff or alluvium. The basement rocks of Paleozoic age,
many thousands of feet thick, are comprised largely of carbonate rocks
in the lower and upper zones and clastic rocks in the middle zone. The
Tertiary volcanic strata consist dominantly of ashflow tuffs of rhyolitic
composition. The aggregate thickness of volcanic rocks is many thousands
of feet, but at most places the volcanic section is less than the total
aggregate thickness, because of erosion or nondeposition. The volcanic
materials were erupted from large volcanic centers known as calderas.
The Timber Mountain caldera, at the west-central part of the NTS, and
the Silent Canyon caldera, buried beneath Pahute Mesa, are two of the
better studied volcanic centers on the NTS. Alluvium covers all of the
intermountain valleys and completely obscures the underlying volcanic
and Paleozoic strata. It is composed of gravels and other detritus
eroded from the adjacent hills and mesas.
Paleozoic rocks are displaced by several large faults of pre-Tertiary
age. Tertiary and Recent basin and range faults cut all of the Tert-
iary and older rocks. Recent alluvium postdates most of the basin and
range faults. Much of the geographical makeup of the entire area is due
to faulting and subsequent upthrusting.
There are two hydrologic systems on the NTS (Figure 3). Groundwater in
the Pahute Mesa system travels at a rate of from 7 to 250 feet per year
to the south and southwest toward the Amargosa Desert. Groundwater in
the Ash Meadows system moves beneath the NTS from north to south at a
rate of from 7.3 to 730 feet/year. Carbon-14 analyses of water from
formations underlying the NTS indicate that the lower velocity is nearer
the true value. At Mercury Valley, in the extreme southern part of the
-------
NTS, the groundwater flow direction shifts to the southwest toward the
Ash Meadows discharge area in the southeastern Amargosa Valley. Best
estimates indicate that it would take over 400 years for water from
underground testing areas to reach the nearest discharge area.
Depths to water on the NTS vary from a few hundred feet beneath the
valleys in the southeastern part of the site to more than 2,000 feet
(3)
beneath the highlands to the north. Although much of the valley
fill is saturated, downward movement of water is extremely slow. The
primary acquifer in these formations is the Paleozoic carbonates.
Nevada Test Site Environs
It is difficult to generalize on the ecology, land use and climate of the
NTS environs with the exception of the very close-in areas. As an example,
within a 200-mile radius west _of the NTS, elevations range from below sea
level in Death Valley, to 14,495 feet above MSL in the Sierra Nevada Range.
Additionally, parts of two valleys of major agricultural importance (the
Owens and San Joaquin) are included. The areas south of the NTS are more
uniform since the Mojave Desert ecosystem comprises most of this portion of
Nevada, California, and Arizona. The areas east of the NTS are primarily
Basin Range Desert with some of the older river valleys, such as the Virgin
River Valley, supporting small scale, but intensive farming and production
of a surprising variety of crops. Grazing is also common in this area, par-
ticularly to the northeast. The area north of the NTS is also Basin Range
Desert where the major agricultural-related activity is grazing of both cat-
tle and sheep. Only areas of minor agricultural importance, primarily alfal-
fa hay, are found in this portion of the state within a distance of 200 miles.
The only major body of water close to the NTS is Lake Mead, a man-made lake
supplied by water from the Colorado River. Lake Mead is the source of water
for almost all domestic, recreational, and industrial purposes in the Las
Vegas Valley. Smaller reservoirs and lakes are located in the area; however,
they are of limited use, primarily for irrigation and for stock water. In
California the Owens River and Haiwee Reservoir feed into the Los Angeles
-------
Aqueduct and are the major sources of domestic water for the Los Angeles area.
Except for the higher elevations, the summers are hot with relatively mild
winters. In the close-in areas, precipitation rarely exceeds 10 inches even
at higher elevations and the relative humidity is low. Prevailing winds are
from the south-southwest in the summer months, while north-northeast winds
are often found during the winter months. Because of the terrain and ele-
vation, any generalization of temperature and wind direction must be qualif-
ied in terms of specific locality.
Dairy farming is not extensive in the 200-mile radius area under discussion.
There are, however, several Grade A dairies located in the Moapa River Valley
in Nevada and in the areas around St. George and Cedar City, Utah. Two small
dairies are located in the Alamo, Nevada area. Other dairies exist in the
Owens Valley in California. It is also fairly common for remote ranches to
keep one or two family milk cows. Within 100 miles of the site there are
about 3,000 dairy cows. The majority of these cows are located at dairy
farms southeast of the NTS, one in the Moapa Valley, several in the Virgin
Valley, and one near Las Vegas.
Population Distribution
One of the prime considerations in choosing the present location of the
Nevada Test Site (formerly the Nevada Proving Grounds) was its isolation
from large population centers while having at least one city close enough
to provide adequate services. The NTS is ideally located in this respect.
With the exception of Las Vegas and vicinity, there are no major popu-
lation centers within 200 miles of the site. There are only about 500,000
people living in this total area, about one-half of whom live in the Las
Vegas greater metropolitan area. If the City of Las Vegas is not con-
sidered in determining population density, there are about two people
per square-mile within the 200-mile radius of the NTS Control Point. For
comparison, the United States (50 states) has a population density of
57.5 per square mile and the overall Nevada average is 4.4 per square
mile.
-------
The off-site areas nearest the NTS (about 50 miles) are predominately
rural. Several small communities are located in the area, the largest
being in the Pahrump Valley. This rural community with an estimated
population of 1,100 is located about 45 miles south of the NTS. The
Amargosa Farm area has a population of about 200 and is located about
30 miles southwest of the center of the NTS. The Spring Meadows Farm
area is a relatively new development consisting of approximately 10,000
acres with a population of somewhat more than 100. This area is about
35 miles south-southwest of the NTS. The largest town in the near off-
site area is Beatty with a population of more than 500 and is located
about 40 miles to the west.
In the adjacent states, the Mojave Desert of California, which includes
Death Valley National Monument, lies along the southwestern border of
Nevada. The population in the Monument boundaries varies considerably
from season to season with fewer than 200 permanent residents and tour-
ists in the area during any given period in the summer months. However,
during the winter, as many as 7,000 tourists and campers can be in the
area, particularly during the major holiday periods. The largest town
in this general area is Barstow, located 165 miles south-southwest of
the NTS with a population of over 12,000. The Owens Valley, where nu-
merous small towns are located, lies 25 to 35 miles west of Death Valley.
The largest town in Owens Valley is Bishop, located 140 miles west-
northwest of the NTS, with a population of about 3,000.
The extreme southwestern region of Utah is somewhat more developed than
the adjacent part of Nevada. The largest town, Cedar City, with a popu-
lation of approximately 9,000 is located 175 miles east-northeast of the
NTS. The next largest community is St. George, Icoated 135 miles east
of the NTS with a population of somewhat more than 7,000.
The extreme northwestern region of Arizona is mostly undeveloped range
land with the exception of that portion in the Lake Mead Recreation
Area.
-------
Several small retirement communities are found along the Colorado River,
primarily at Lake Mojave and Lake Havasu. The largest town in the area
is Kingman, located 175 miles southeast of the NTS, with a population of
about 6,000.

Other Test Sites
Underground nuclear detonations have been conducted for various special pur-
poses at sites other than the NTS. The NERC-LV has sampled various media,
mostly water, at each of these locations during 1972.
Two of the sites are designated as supplemental test areas by the AEC. These
are the Central Nevada Test Area located in the Hot Creek Valley about 60
miles east of Tonopah, Nevada, and Amchitka Island, Alaska, located 1,340
miles west-southwest of Anchorage, Alaska.
The other underground nuclear events were conducted in Colorado, Nevada, New
Mexico, and Mississippi. Table 1 shows the name, date, location, yield,
depth, and purpose of all underground tests conducted off the NTS.
-------
SUMMARY
During 1972, the monitoring of gamma radiation levels and concentrations of
radioactivity in the environs of the NTS was continued through the use of
off-site networks of radiation dosimeters and gamma-rate recorders, air sam-
plers, and selected locations at which monthly samples of water and milk were
collected for radiological analyses. For each of the underground nuclear
detonations and the seven experimental tests of the Nuclear Furnace-1, mobile
radiation monitors equipped with radiation monitoring equipment and supplies
were on standby in off-site locations to respond to any inadvertent release
of radioactivity which might result in a radiological hazard to off-site
populations and property.
The only radioactivity produced by nuclear tests at NTS and detected off-site
was 133Xe, which was observed in samples collected at stations of the Noble
Gas and Tritium Sampling Network at Beatty, Diablo, and Hiko, Nevada. The
levels of 133Xe, which were attributed to gaseous seepage from underground
tests, occurred only in a few samples. These levels, averaged over the total
period sampled during the year, were less than 0.04% of the Concentration Guide
of the AEC Manual, Chapter 0524, for a population sample. All other increases
in radioactivity concentrations observed in media collected around the NTS were
attributed to seasonal variations in old atmospheric fallout and fallout from
nuclear detonations by the People's Republic of China on January 7, 1972, and
March 18, 1972. Radioactive noble gases were released during the Nuclear
Furnace-1 test series and detected by aircraft sampling; however, no radioac-
tivity was detected on the ground beyond the combined areas of the Nellis Air
Force Range and the NTS. Based upon the aircraft results, an estimate of the
potential radiation exposure to off-site populations was determined to be less
than 1% of the Radiation Protection Standards of the AEC Manual, Chapter 0524.
The results of soil samples collected around the NTS and analyzed for plutonium
content showed that 23^Pu is present outside the boundaries of the NTS at levels
greater than that which would be expected from world-wide fallout(=1 nCi/m2).
Further soil sampling, analyses, and evaluations will be conducted in 1973 to
-------
complete a map showing the variation in deposition levels on and around the
NTS and to improve the precision of sampling techniques.
During the year, a Long-Term Hydrologic Monitoring Program was begun for
off-NTS sites used previously for underground nuclear tests. These sites
are located near Fallen, Nevada (Project Shoal), Central Nevada Test Area
(Faultless Test), Grand Junction, Colorado (Project Rulison), Farmington,
New Mexico(Project Gasbuggy), Carlsbad, New Mexico (Project Gnome), Hatties-
burg, Mississippi (Projects Dribble/Miracle Play). This program was ini-
tiated to annually check radioactivity concentrations in wells, springs, and
surface waters which are down-gradient from ground waters at the project
sites. All radioactivity concentrations in the samples collected during the
year were at natural background levels with the exception of samples collected
at USGS Wells Nos. 4 and 8 at the Project Gnome site and the HT-2M Well at the
Project Dribble/Miracle Play site. The USGS wells at the Gnome site were used
in a U.S. Geological Survey radioactive tracer study in 1963, at which time
137Cs, 131I, 90Sr, and 3H were injected into Well No. 8 and water was pumped
out of Well No. 4. As a result, high levels of 3H and 90Sr were observed in
samples collected from both wells while 137Cs was detected only in the sample
from Well No. 8. The highest concentration of radioactivity was for 90Sr,
which was 4.3 times its Concentration Guide of 3 x 10 yCi/ml for exposure to
individuals. The HT-2M Well at the Dribble site was drilled about 200 feet
from another well in which 338,000 gallons of radioactive waste was injected
during CY 1965. During this report period, high levels of 3H was detected
in the well, the highest being 6.7 x 10~ yCi/ml, which is 2.2% of the Concen-
tration Guide for 3H. The radioactivity concentrations of all other samples
collected from wells near the contaminated wells were below the Concentration
Guides and representative of normal background levels. All of the contami-
nated wells are fenced, locked, and posted to ensure that the wells are not
used by unauthorized persons.
The potential radiation dose equivalents received by off-site populations near
the NTS and other locations referred to above were all estimated to be less
than 1% of the Radiation Protection Standards of the AEC Manual, Chapter 0524.
These estimates were based upon actual measurements of gamma radiation levels
at off-site populated locations and measurements of radioactivity concentrations
in the pathways of exposure as close to off-site residents as possible, i.e.,
air, milk and water.

MONITORING DATA COLLECTION, ANALYSIS, AND EVALUATION
The major portion of the off-site radiological safety program for the NTS
consists of continuously-operated dosimetry and air sampling networks and
scheduled collections of milk and water samples at locations surrounding
the NTS. Before each nuclear test, mobile monitors were positioned in the
off-site areas most likely to be affected by a possible release of radio-
active material. These monitors, equipped with radiation survey instru-
ments, gamma-rate recorders, thermoluminescent dosimeters, portable air
samplers, and supplies for collecting environmental samples, were prepared
to conduct a monitoring program directed from the NTS Control Point by two-
way radio communications. In addition, for each event at the NTS, a U. S.
Air Force aircraft with two NERC-LV monitors or two Reynolds Electric Com-
pany monitors equipped with portable radiation survey instruments was air-
borne over surface ground zero to detect and track any radioactive effluent.
Two NERC-LV cloud sampling and tracking aircraft were also available to
obtain in-cloud samples, assess total cloud volume, and provide long-range
tracking in the event of a release of airborne radioactivity.
To assess the plutonium content of soil in areas surrounding the NTS, a
special soil study was continued. In addition, a Long-Term Hydrologic
Monitoring Program for the NTS and off-NTS underground test areas (except
Amchitka, Alaska where the U. S. Geological Survey is performing this
function) was begun to monitor radioactivity concentrations in wells, springs,
and surface waters which are down gradient of underground water near areas
where underground detonations have been performed. The first annual sampling
for the Long-Term Hydrologic Monitoring Program for off-NTS project areas was
completed during the year; however, routine sampling at the NTS did not com-
mence until January 1973. Integrated monthly samples of the water of combus-
tion of natural gas were also collected by a burner/condenser system on a
trunk line carrying gas from producing wells adjacent to the Project Gasbuggy
Site near Farmington, New Mexico,to determine if 3H might possibly be enter-
ing the producing wells.
Nevada Test Site
No radioactivity was detected beyond the boundaries of the Nevada Test Site
11
-------
following the tests conducted during CY 1972.
At the Nuclear Rocket Development Station (NRDS), located in the southwest
corner of the NTS, an experimental reactor, Nuclear Furnace-1, was operated
seven times during May, June, and July 1972. Table 1 lists the date/times
and integrated power in Mw*sec. Although radioactivity was detected by
aerial monitoring and sampling aircraft, no effluent was detected off-site
by ground monitoring systems. Since the monitoring and sampling by air-
craft were performed over the NTS and Nellis Air Force Range, the effluent
monitoring data were reported separately to the AEC in accordance with the
AEC Manual, Chapter 0513.

The radionuclides detected by aircraft sampling in the Nuclear Furnace-1
effluent were noble gases and daughter products of noble gases; no partic-
ulates originating in the reactor or radioiodines were detected by aircraft
sampling. An estimate of the potential external gamma radiation exposure
at the off-site boundary of the combined areas of the Nevada Test Site and
the Nellis Air Force Range was, for the test series, less than 1$ of the
Radiation Protection Standards of the AEC Manual, Chapter 0524. This esti-
mate was based upon what one might receive at the site boundary if one were
within the effluent from each test and at the elevation of the maximum
radioactivity concentrations, which actually ranged between 2500 feet and
9000 feet above any off-site population.

A description of NTS sampling networks, and the results from these networks,
follows.
Air Surveillance
The Air Surveillance Network, operated by the NERC-LV, consisted of
104 active and 18 standby sampling stations located in 21 western
states (Figure 6). Samples of airborne particulates were collected
continuously at each active station on 4-inch-diameter glass-fiber
filters at a flow rate of about 350 m3 of air per day. Normally sam-
ples were collected over a 24-hour period; however, at several sta-
tions operated by state health department and other government agency
personnel, they were not always collected on weekends and holidays,
which resulted in 48- or 72-hour samples. Activated charcoal car-
tridges directly behind the glass-fiber filters were used regularly
for the collection of gaseous radionuclides at 22 stations near the
NTS. Charcoal cartridges could have been added to all other stations
by telephone request. The stations were operated by state health
department personnel and by private individuals through contract agree-
ments. All air samples were mailed to the NERC-LV unless special re-
trieval was arranged at selected locations in case of a known release
of radioactivity from the NTS0
The glass-fiber filters were counted five minutes for gross beta
radioactivity as soon as they were received and again at 5 and 12 days
after collection. Samples were counted on gas flow proportional
counters calibrated over a range of beta energies from 0.1 to 1.8 MeV.
A conservative efficiency value of 45% (corresponding to an average
maximum beta energy of 0.5 MeV) was used for data conversion. The 5-
and 12-day counts were used to extrapolate gross beta concentrations
to mid-collection time for reporting. Extrapolation was accomplished
by computer programs and was routinely based on a T"1'2 decay. For
known releases of particulate radioactivity, which for 1972 occurred
only from nuclear tests by the People's Republic of China, the decay
rate was determined experimentally and used in the extrapolations.
13
-------
Those filters with total gross beta radioactivity of 500 cpm or
greater were gamma scanned on a 4- by 4-inch sodium iodide (Tl-
activated) crystal connected to a 400-channel gamma spectrometer.
Individual radionuclides were quantitated from spectrometer data by
use of a computer matrix technique. If fresh fission products re-
lated to a NTS event had been detected, radiochemical analyses, such
as strontium and plutonium, would have been made on selected filters.
All charcoal cartridges were counted 10 minutes with a gamma spec-
trometer. Data from those cartridges having a net gross gamma count
rate greater than 300 cpm were analyzed by computer matrix technique
to quantitate individual radionuclides. Additional analytical infor-
mation can be found in Table 3.
Table 4 presents the maximum, minimum detected and average concentra-
tions of gross beta radioactivity and individual radionuclides iden-
tified by gamma spectroscopy for each location within the network
during 1972. The annual gross beta average was determined for each
station by summing the station's monthly averages and dividing by
twelve, assuming all monthly averages less than the minimum detectable
concentration to be equivalent to the minimum detectable concentration.
Each annual average for a radionuclide detected at a given station was
derived by dividing the sum of its time-integrated concentrations
(pCi-day/m3) by 366 days. This was done assuming that these radio-
nuclides were not present on those filters which did not exceed the
screening level of 500 cpm, or 1.4 pCi/m3 for a 45% counting efficien-
cy and normal sample volume of 350 m3. This is consistent with the
AEG Manual, Chapter 0524, which allows one to consider radionuclides
to be absent in a mixture ". . . if (a) the ratio of the concentration
of that radionuclide in the mixture. . .to the concentration guide
for that radionuclide. . .does not exceed 1/10, and (b) the sum of
such ratios for all the radionuclides considered as not present in
the mixture does not exceed 1/4. . . .
As shown by Table 4, the fission products 95Zr, 103Ru, 131I, l32Te,
14°Ba, 141Ce, S37U, and 339Np were detected in varying combinations
14
-------
at all but four sampling locations. None of these radionuclides
were associated with nuclear tests at the NTS, since their occurrence
throughout the network followed the seasonal trend expected for world-
wide fallout and corresponded with the nuclear detonations by the
People's Republic of China on January 7, 1972, and March 18, 1972.
An example of the variation of gross beta concentrations during the
year is shown in Figure 7.
Noble Gas and Tritium Sampling Network
During the months of March and April 1972, a routine air sampling net-
work for monitoring levels of radiokrypton, radioxenon, and 3H in the
form of HT, HTO, and CHgT was established for the NTS. Due to infre-
quent releases of radioactive gas during drill-back into the shot
zone and occasional gaseous seepage from underground shot locations,
the AEG Nevada Operations Office requested the NERC-LV to design,
field and operate this Network at four on-NTS and six off-site loca-
tions. The locations of the off-site sampling stations are Las Vegas,
Beatty, Tonopah, Diablo, and Hiko, Nevada, and Death Valley Junction,
California. The off-site stations may be located by referring to
Figure 6.
The equipment used in this Network is designed in two separate sys-
tems: one is a compressed air sampler, and the other is a molecular
sieve sampler. The compressed air equipment continuously samples air
which is then compressed and stored over seven-day periods in two
pressure tanks, which together hold approximately two cubic meters of
air at atmospheric pressure. The bottles are replaced weekly and re-
turned to NERC-LV where the samples are analyzed for radionuclides of
Kr and Xe and for CH3T by gas chromatography and liquid scintillation
techniques summarized in Table 3 and described by Stevenson and Johns.
The molecular sieve type equipment samples air through a filter to re-
move particulate matter and then through a 600-gram column of 13X
molecular sieve to remove atmospheric water. Tritium-free hydrogen
15
-------
carrier is added to the air stream by electrolysis of antique water.
The air is then passed through another molecular sieve column to re-
move any water from the electrolysis cell. The dry air with added
hydrogen is then passed through a palladium catalyst supported on
13X molecular sieve. The hydrogen is converted to water, which is
immediately adsorbed on the molecular sieve. The volume of air
passed through the sampler is measured by a dry gas meter. Approxi-
mately five cubic meters of air are passed through each sampler over
a seven-day sampling period. After each sampler is returned to the
laboratory, the first molecular sieve column and the catalytic col-
umn are degassed; the water is distilled and analyzed for tritium by
liquid scintillation techniques.
Table 5 summarizes the results of this Network by listing the maxi-
mum, minimum, and average concentrations for 85Kr, total Xe or 133Xe,
CHsT, 3H, HTO, and HT. The annual average concentrations for each
station were calculated over the time period sampled assuming that
all values less than the Minimum Detectable Activity (MDA) were
equal to the MDA, In the table, all concentrations of 85Kr, Xe or
133Xe, CH3T, HTO and HT are expressed in the same unit, jjjCi per ml
of air; the concentrations of 3H (representing 3H in water vapor)
are reported in the unit yCi per ml of atmospheric moisture.
As shown by Table 5, the maximum and average 8BKr levels at all sta-
tions were essentially the same, indicating no contribution from NTS
operations. The concentrations of 3H, HTO and HT were generally the
same at all locations through the year except for the on-site stations
at BJY and Area 12, where concentrations of 3H, HTO and HT reached a
maximum of 1.3 x l(T4(j,Ci/ml, 9.1 x 1CT 10|j,Ci/ml, and 2.3 x 10~i:L|u,Ci/ml,
respectively. All average concentrations for the year were less than
0.01% of the Concentration Guides for 3H in air, which is 6.7 x 10~8
luCi/ml for exposure to an off-site population sample and 5.0 x 10~6
for exposure to a radiation worker. No tritium in the form of CHgT
was detected above its MDA of 5 x 10~12juCi/ml at any of the stations.
16
-------
The concentrations of Xe were below the MDA of 2 x 10" 12|j,Ci/ml at all
stations throughout the year except for Beatty, Diablo, and Hiko,
Nevada, and the on-site locations Desert Rock, BJY, and Area 12. At
these stations 133Xe was detected on a few occasions with concentra-
tions as high as 5.7 x 10~10(j,Ci/ml at Hiko. The average concentra-
tion at all locations was below 0.04$ of the Concentration Guide for
this nuclide, which is 1 x 10~7p,Ci/ml for an off-site population sam-
ple and 1 x 10~^(o,Ci/ml for on-site radiation workers.
Dosimetry Network
The Dosimetry Network during 1972 consisted of 88 locations surround-
ing the NTS which were monitored continuously with thermoluminescent
dosimeters (TLD's). The locations, shown in Figure 8, are all within
a 300-mile radius of the center of the NTS and include both inhabited
and uninhabited locations. Each Dosimetry Network station was equipped
with three EG&G Model TL-12 dosimeters, which were exchanged monthly.
Within the general area covered by the dosimetry stations about 60
off-site residents routinely wore one TLD each. These dosimeters
were exchanged at the same time as the station dosimeters.
The TL-12 dosimeter has an internal or self-background exposure rate
equivalent to 0.7 mR/day, which limits its minimum detection to about
5 mR for a 30-day measurement period. All TLD readings were corrected
to 137Cs gamma-roentgen-equivalent values according to individual TLD
calibration factors. For purposes of this report, these units of ex-
posure were considered to be equivalent to whole-body gamma doses in
rems.
After appropriate corrections were made for the background exposure
accumulated during shipment between the laboratory and the monitoring
locations, the three TLD readings were averaged. The average expo-
sure value for each month and station was statistically compared to
values from the past twelve months to determine whether the new value
was within the range of environmental background, or significantly
17
-------
greater than background. Those which were greater led to calculations
of net exposures, whereas those, which were not, were pooled with the
background data bank, and the oldest value in the data bank was de-
leted. Values which were statistically lower than the background range
were also deleted and considered invalid measurements. Each of the 60
personnel dosimeter readouts was compared to the background value of
the nearest station.
No doses related to nuclear testing were detected by the dosimetry
network during 1972. Table 6 lists the maximum, minimum, and average
dose equivalent rate (mrem/d) measured at each station in the network
during 1972. The maximum and minimum dose rates were selected from
dose rates determined from monthly exposures (mrem) divided by the
number of days in the exposure period, which was about 30 days depend-
ing on minor variations in schedules. The annual average dose rate
for each station was calculated by adding the monthly dose equivalent
values (rarea) and dividing the sum by the number of days in the period
listed in Table 6 for each station. The annual adjusted background
dose was derived from the product of the annual average dose rate and
366 days. As shown by this table, the average station background
doses ranged from 84 to 200 mrem with a network average of 144 mrem/a.
Among the approximately 60 off-site residents who wore dosimeters con-
tinuously, no personnel doses greater than background were detected
as a result of nuclear testing at NTS.
Several TLD's showed unexplained high readings during 1972. These
values, listed in Table 7, are considered to be anomalous readings,
not true gamma exposures. Surveys of the locations and interviews
with the individuals involved identified no sources of radiation which
would produce the exposures. Also, in the case of the stations where
three TLD's were issued each month, only one or two dosimeters read
high. It is believed that the anomalies were due to phenomena asso-
ciated with the TLD's rather than some external radiation source.
18
-------
A network of 32 stationary Eberline RM-11 gamma rate recorders placed
at selected air sampling locations was used to document gamma expo-
sure rates at fixed locations (Figure 6). These recorders used a GM
tube detector with a 0.01 to 100 mR/h range and were calibrated to
±20% with a 137Cs source. The gamma exposure rates were recorded on
30-hour strip charts, which were exchanged and mailed to the NERC-LV
each day. No gamma exposure rates attributable to NTS operations
were detected by the network of gamma rate recorders.
Starting in July 1972, the RM-11 gamma rate recorders were gradually
replaced by a NERC-LV designed recorder designated as the LSI. This
recorder uses a 1- by 12-inch constant-current ionization chamber
detector filled with methane. The recorder operates on either 110V
a.c. or on a self-contained battery pack. This radiation monitor
records gamma radiation levels from .004 mR/h to 40 mR/h with a log-
arithmic response and an accuracy of better than ±10%. The recorder
chart runs at a speed of three inches per hour so that one chart will
last for 10 days, although the charts are mailed to NERC-LV weekly.
A fresh battery pack will operate the monitor for about two weeks at
radiation levels below 1 mR/h and about five days at radiation levels
above 1 mR/h. The length of unattended operations from a.c. line
power is limited only by the need to change paper in the recorder.
During this report period, no increase in exposure rates attributable
to NTS operations was detected by the network of gamma rate recorders.
Milk Surveillance Network
Milk is only one of the sources of dietary intake of environmental
radioactivity; however, it is a very convenient indicator of the gen-
eral population's intake of biologically significant radionuclide
contaminants. For this reason it is monitored on a routine basis.
Few of the fission product radionuclides become incorporated into the
milk of the cow due to its selective metabolism. However, those that
are incorporated are very important from a radiological health stand-
point, and since they are preferentially transferred to the cow's
19
-------
milk, it is a very sensitive measure of their concentrations in the
environments. The five most common fission product radionuclides
which can occur in milk are 89Sr and 9°Sr, 131I, 137Cs, and 14°Ba.
A sixth radionuclide, 4°K, also occurs in milk at a reasonably con-
stant concentration of about 1.2 x 10~6p,Ci/ml. Since this is a nat-
urally occurring radionuclide, it was not included in the analytical
results summarized in this section.
The milk surveillance networks operated by the NERC-LV were the rou-
tine Milk Surveillance Network (MSN) and the Standby Milk Surveillance
Network (SMSN). The MSN during 1972 (Figure 9) consisted of 35 dif-
ferent locations at which NERC-LV personnel collected one-gallon milk
samples from family cows, commercial pasteurized milk producers,
Grade A raw milk intended for pasteurization, and Grade A raw milk
for local consumption. In the event of a release of activity from
the NTS, intensive sampling would have been conducted in the affected
area within 300 miles of the NTS to assess radionuclide concentrations
in milk, radiation doses that could result from the ingestion of the
milk, and the need for protective action. Milk supplies and producers
beyond 300 miles are sampled with the SMSN.
During 1972, 321 milk samples were collected from the MSN. Of the 35
locations, five were alternates where milk was sometimes obtained in
the event the primary sampling point did not have milk available.
Although the routine locations were scheduled for monthly collection,
milk could not usually be obtained at all locations in any one month.
Cows not lactating, no one home, or no milk on the day the route
monitors arrived at the ranch, were some of the reasons why some of
the samples were not collected each month. During the year, milk
sampling points also changed as cows were sold, or were otherwise
unavailable for regular milkings.
The SMSN consisted of about 185 Grade A milk processing plants in all
states west of the Mississippi River which could be requested by
20
-------
telephone to collect raw milk samples representing milk sheds supply-
ing milk to the plants. Since there were no releases of radioactivity
from the NTS or other test locations, this network was not activated
except to request an occasional sample to check the network readiness
and reliability. No analytical results are reported here for the
SMSN, since only one sample was received from each of several selected
locations and were not associated with any particular nuclear activity
or installation.
All milk samples were analyzed for gamma emitters, 89 Sr and 9°Sr.
Samples collected at six locations from the MSN were routinely ana-
lyzed for 3H. Table 3 lists the general analytical procedures and
fo\
detection limits for these analyses as described by Johns and Lem
(9)
and Snelling. For gamma spectroscopy analyses, the milk was
placed in 3.5-liter Marinelli beakers which position the samples
around the crystal detecCor for high counting efficiency. All rou-
tine milk samples were counted for 40 minutes. A computer was used
to calculate the activity concentration of each of the detected nu-
clides at the time of count and extrapolate the results to time of
milking.
The analytical results of milk samples collected from the MSN during
1972 are summarized in Table 8. The maximum, minimum, and average
concentrations of the 137Cs, 89Sr,, 9°Sr, and 3H in samples collected
during the year are shown for each sampling location at which these
analyses were scheduled. In the computation of the average concen-
trations, sample concentrations of less than the minimum detectable
concentration were assumed to be equal to the minimum detectable con-
centration. If any of the values used in computing the averages were
"less than" values, the average was expressed as a "less than" value.
During the year, there were a few samples which did not have enough
volume to provide the usual minimum sensitivity for gamma spectrum
analysis for 137Cs (1.0 x 10~8(iCi/ml) . In these cases, the minimum
sensitivity was 1.0 x 10~7|j,Ci/ml.
21
-------
No radionuclides from NTS operations were detected in any of the
milk samples. The levels of 137Cs, 89Sr, and 90Sr varied during the
year in accordance with what is normally observed due to variations
in world-wide fallout. An example of the trends in concentrations
during the year is shown for the Martin Ranch in Figure 7. The
variations in concentrations agree reasonably well with the variation
in gross beta concentrations in air at the three nearest air sampling
locations, Austin, Round Mountain, and Eureka, Nevada.
Water Surveillance Network
The Water Surveillance Network (WSN) operated in off-site areas
around the NTS during 1972 consisted of 91 locations (Figures 10 and
11) where NERC-LV personnel collected one-gallon water samples. The
samples were collected from community water supplies, wells, open and
closed springs, streams, lakes, and ponds. If a release of radioac-
tivity from NTS had occurred, special sampling within the affected
area would have been conducted to determine radionuclide concentra-
tions and the possible need to take protective action.
During 1972, 1022 water samples were collected from these 91 locations.
All samples were scheduled to be collected monthly, except those from
Walker Lake and Pruess Reservoir. These two locations were sampled
quarterly. In some cases operational priorities, frozen sources, etc.,
prevented the sampling of each location every month.
All water samples from the WSN were analyzed by gamma spectroscopy
and counted for gross alpha and gross beta radioactivity. Network
samples from approximately 25 locations west, south, and southeast of
NTS were also routinely analyzed for 3H. For the purpose of identi-
fying the source of the gross radioactivity in all network samples and
comparing sample concentrations with the Concentration Guides of the
AEG Manual, Chapter 0524, selected samples were given special analyses
at least once during the year. For surface water samples, the special
analyses included 89-9°Sr, 23e-239pUj ^ and 226 Ra> For drinking water
22
-------
samples,, the analyses included 89-9°Sr, U, and 22S Ra. Table 3 lists
/g\
the general analytical procedures as described by Johns , Lem and
Snelling^ , and Talvitie^ ' ' and the detection limits.
The analytical results of all water samples collected from the WSN
during 1972 are summarized in Table 9, which lists the maximum, mini-
mum, and average concentrations of radioactivity detected in the sam-
ples. No gamma-emitting fission products were detected in any of the
samples by gamma spectroscopy analysis. No significant trends were
observed in the gross alpha, gross beta, or 3H results, although sur-
face waters generally contained higher concentrations than ground
waters. The higher concentrations were attributed to world-wide fall-
out and naturally occurring radionuclides.
The average concentrations for the gross alpha, gross beta, and 3H
radioactivity compared to the following Concentration Guides speci-
fied in AEG Manual, Chapter 0524 for exposure of individuals:
Type of Radioactivity Concentration Guide uCi/ml
Gross alpha 3 x 10~8
Gross beta 3 x 10~8
3H 3 x 1(T3
Those locations which had an annual average concentration greater
than these Guides are Hiko, Schofield Dairy (gross beta C = 3.2 x
l(r8/LtCi/ml), Comins Lake (gross beta C = 3.6 x 10~8^Ci/ml), Walker
Lake (gross beta C = <1.9 x 1CT7 juCi/ml), and Fallini's Pond (gross
beta C = 6.9 x 1CT8 uCi/ml). Of these sources only the Schofield
Dairy water is consumed by humans. As shown in Table 9, samples from
the locations that were selected for special analyses contained natu-
rally occurring uranium isotopes and daughters including 236Ra. This
would account for the high gross beta activities. In addition to the
special analysis given the sample from Walker Lake, the sample was
also given a longer gamma count in an effort to determine the source
23
-------
of the relatively high gross beta activity, since the concentrations
of uranium and daughter products could not account for all of the
gross beta radioactivity. Potassium-40, with a concentration of 1.2 x
1CT7 (j,Ci/ml, was found to be the isotope responsible for the elevated
beta activity. Including the naturally occurring radionuclides listed
above which did not result from NTS operations, the radioactivity
concentrations in water were less than the values listed in the AEC
Manual, Chapter 0524.
Plutonium in Soil
This program began in September 1970 as an integral portion of the
work coordinated by the Nevada Applied Ecology Group (NAEG). The
NAEG was formed by the AEC to coordinate environmental evaluations
corresponding to specified areas of AEC operations. The NAEG's ob-
jective in the study is to determine the inventory, distribution, and
movement in the ecosystem of on-site and off-site plutonium which was
produced by NTS operations.
As part of this study, the NERC-LV was involved in investigating off-
NTS air and soil for plutonium content. Air sample analyses have been
limited to filters collected at selected Air Surveillance Network Sta-
tions (ASN) over a period from 1965 to 1972. Two phases of research
have been conducted. Filters from eight air sampling stations distri-
buted over the western United States were chosen for analyses to deter-
mine ambient levels of world-wide fallout. Filters were selected for
five sampling days near the middle of each month and a plutonium assess-
ment made on a composite of filters. The second phase was to analyze
filters collected near the NTS. Stations were selected which were lo-
cated upwind and downwind of known on-site plutonium deposition areas.
Filters were chosen for days when high winds and dry soil conditions
existed in the general area of the NTS. Results will be reported on
completion of the analyses of these filters.
Initial soil sampling began in September 1970. The selected sampling
method was first field tested and refined to suit operational and
analytical requirements. This method is defined as the trench method.
24
-------
A trench was dug and a sample was removed from one aide of the trench,
over a given surface area, and at various sampling depths. By this
method a preliminary soil profile sampling survey was performed to
determine the vertical distribution of plutonium and to define an
optimum sampling depth. Since this preliminary survey showed that 90%
of the plutonium concentrations were found in the top 3 cm of soil in
90% of the samples collected, a 5 cm depth was chosen with a sampling
area of 10- by 10-cm. Ten 10- by 10-cm cores were composited to form
a total sampling area of 1000 cm2 for each sample location. All sam-
pling sites were chosen from undisturbed desert "pavement" areas at
the intersections of a 5- by 5-mile grid, as much as possible.
Each sample was returned to the NERC-LV in a polyethylene bag and air
dried. The total weight was measured and the sample screened with a
U. S. Standard screen o£ 10-mesh. The portion passing through the
10-mesh screen was divided with a Jones sample splitter. Successive
splits were made to achieve a sample of about 50 g for Pu analysis.
The remainder of the fraction passing 10-mesh was redivided to yield
a sample size of about 600 g, which was gamma counted. The 50 g sam-
ple for Pu analysis was oven dried and pulverized to less than 200
mesh. A one gram aliquot was then collected from this sample for
complete dissolution in hydrofluoric acid; the Pu being separated
from the solution by ion exchange techniques and electrodeposited on
a stainless steel planchet for alpha spectrometric analysis. '
The results of soil samples collected around the NTS and analyzed for
plutonium content showed that 239Pu is present outside the boundaries
of the NTS at levels greater than that which would be expected from
world-wide fallout («1 nCi/m2). Since all analytical results are pre-
liminary, none are reported at this time. Further sampling, sample
analyses, and evaluations will be conducted in 1973 to complete a map
of off-site plutonium deposition levels and to improve the precision
of the data.
25
-------
Other Test Sites
Two programs were operative in 1972 to provide additional data on long-term
surveillance at all continental test sites, past and present. The two pro-
grams now in effect are (1) sampling for % in natural gas from wells adjacent
to the Gasbuggy Test Well near Farmington, New Mexico, and (2) scheduled
water sampling of wells and other water sources in the vicinity of all con-
tinental sites. A description of the two programs are included in this
section.
Natural Gas Burner Sampling, Gasbuggy Site
During 1972, integrated monthly samples of the water condensate from the
combustion of natural gas were collected from a truck line servicing 28
natural gas wells adjacent to the Gasbuggy Test Well near Farmington,
New Mexico. This study, which became routine by November 1971 follow-
ing the development of a gas burner system, was initiated to determine
if natural gas from the nuclear-stimulated Gasbuggy Test Well would in-
troduce radioactive contaminants into the surrounding producing wells.
Tritium was chosen as a suitable indicator of radioactive contamination.
(14)
With the use of the gas burner system described by Connolly, an air/
gas mixture flows through a combustion chamber where it is continuously
burned. The resultant water vapor is condensed out of the exhaust gases
and collected. Each month the condensate is sent to the NERC-LV for
liquid scintillation counting for 3H.
All concentrations of 3H in the twelve monthly condensate samples col-
lected in CY 1972 were below the minimum detectable activity of about
220 pCi/1 of condensate water.
Long-Term Hydrologic Monitoring Program
In addition to the continuous program of underground nuclear testing at
the NTS, several special purpose underground tests have been conducted
in various parts of the continental United States and Alaska (Table 1).
26
-------
Following each of these events, all surface material contaminated with
radioactivity was removed or otherwise disposed of in accordance with
appropriate decontamination procedures. Other than an improbable seep-
age of minor amounts of gaseous radionuclides into the atmosphere, the
only other method for radioactivity to enter the biosphere beyond the
immediate vicinity of the detonation area would be by transport'in
ground waters from the cavity and/or rubble chimney created by the det-
onation.
In previous years, hydrologic monitoring and investigation programs
were conducted for the AEC by the U. S. Geological Survey (USGS) and
Teledyne Isotopes (formerly Isotopes, Inc.). As a continuation of
this effort, the AEC requested the NERC-LV to establish a Long-Term
Hydrologic Monitoring Program in the vicinity of all active and in-
active test areas. The purpose of this program, as outlined by the
Nevada Operations Office, AEC, is to obtain and record appropriate data
from reliable sources adequate to:
1) Assure the public safety;
2) If the need should arise, to inform the public, the news media,
and the scientific community;
3) Document compliance with existing Federal, state, and local
anti-contamination requirements.
To implement this long-term program, NERC-LV began sampling water from
wells, springs, and surface waters which are down-gradient of the move-
ment of ground water at the sites of Project Shoal, Project Dribble,
Project Gnome, Project Gasbuggy, Project Rulison, and the Faultless
Event of the Central Nevada Test Area (CNTA). The sampling frequency
for each site was established as once a year in the early spring plus
once during any period of flaring of natural gas at those sites where
flaring is undertaken. No flaring operations were conducted at any of
the sites during this report period.
Samples of underground water sources were collected from well heads or
27
-------
spring discharge points where possible. If pumps were not available,
an electrical-mechanical water sampler capable of collecting a 3-liter
sample at depths up to 6000 feet was used. Samples for 3H analysis
from each location were collected in two 16-ounce glass bottles each
fitted with a poly-seal screw cap. The bottles were filled with un-
filtered water, capped and then sealed with black plastic tape. Sam-
ples for radiochemical analysis from each location were collected in
one gallon plastic cubitainers. The cubitainers were filled with filt-
ered water (water passing a 0.45 ym filter) and the contents adjusted to
pH 1 using concentrated nitric acid.
Most samples were analyzed for 3H, gross alpha, and gross beta by ra-
diochemistry techniques and for gamma-emitters by gamma spectroscopy;
however, there were some wells and surface supplies for which only H
analysis was performed. Selected samples were also analyzed for 89~9(JSr
and 22°Ra. A complete summary of analytical procedures and detection
limits is shown in Table 3.
The analytical results of all water samples collected during 1972 are
summarized in Table 10. For each concentration, the percent of the ap-
propriate Concentration Guide as specified in the AEC Manual, Chapter
0524, was calculated and listed. As shown by the table, concentrations
of radioactivity above the Concentration Guides were found in samples
collected at the sites of Project Dribble and Gnome. Well HT-2M, which
is located on the Project Dribble site, is approximately 200 feet from
Well HT-2 in to which approximately 338,000 gallons of radioactive
liquid waste were injected during 1965. As a consequence of this, high
levels of 3H were observed at most depths sampled in HT-2M. The maxi-
mum concentration observed was 6.7 x 10~5yCi/ml in a sample collected
from 2350 feet below the surface on October 14, 1972. This concentration
was 2.2% of the Concentration Guide for 3H as specified in the AEC Man-
ual, Chapter 0524, for exposure to an individual. Although these con-
taminated wells are on private land, the wells are fenced, posted, and
locked to prevent their use by unauthorized personnel.
28
-------
USGS Wells Nos. 4 and 8 located on the Project Gnome site were used in
a USGS radioactive tracer study during the first quarter of 1963. Ce-
sium-137, 131I, 90Sr, and 3E were injected into Well No. 8, and water
was pumped from nearby Well No. 4. As a result of this study, high
levels of 3H and 90Sr were observed in samples collected from both wells
in 1972, while 137Cs was observed only in the sample from Well No. 8.
As indicated by Table 10, the highest concentration was for 90Sr, which
was 4.3 times its Concentration Guide. The concentrations of radioac-
tivity in all the other wells sampled near the two contaminated wells
were below the Concentration Guides and representative of normal back-
ground levels. These two contaminated wells, which are on federal land,
are also fenced, locked, and posted to assure that they are not used by
unauthorized personnel.
Gross beta levels above 30 pCi/1 were also observed in samples collected
from Flowing Well No. 2 (3.8 x 10~8yCi/ml) near the Project Shoal site,
and Lake La Jara (3.6 x 10~8yCi/ml) and El Paso National Gas Well 10-36
(4.7 x 10~8yCi/ml), both of which are near the Project Gasbuggy site.
None of these sources of water are used for domestic purposes. Further
analysis will be performed on these samples to identify the radionuclides
contributing to the gross radioactivity.
