                            ABSTRACT

Under a Memorandum of Understanding with the U. S.  Atomic Energy
Commission,  the U. S. Public Health Service conducted a program of
environmental surveillance for Operation Niblick,  a series of nuclear
experiments carried out at the AEC's Nevada Test Site during the pe-
riod July  1, 1963, through June 30,. 1964.   This report contains the
results of this surveillance.
Of the twenty-six announced events of Operation Niblick, including four
Plowshare events, two released radioactivity to the environment im-
mediately after detonation which was subsequently detected on the
ground in the  off-site areas.  These events were Eagle, conducted on
December 12, 1963 and Pike, conducted on March 13,  1964.
The Eagle Event release was not detected  by ground monitors but low
concentrations of fresh fission products (maximum,  20 pCi/m3  133I)
were  detected on charcoal cartridge air filters  at four air sampling
stations located south of the Nevada Test Site.  No fresh fission pro-
ducts were found in milk or water samples collected in downwind areas.
The Pike  Event resulted in a release of radioactive effluent that was
detected by various sampling techniques as far  south as Yuma, Arizona.
Maximum measurements  by portable ground monitoring instruments
in the off-site areas were  relatively low (maximum, 5.9 mR/hr net
gamma).  Areas in the cloud path experienced low, but detectable,
residual contamination on  vegetation and in some milk samples.
Maximum external and internal exposures to the off-site population
as a result of any one,  or  combination of,  Operation Niblick  events
were  below the safety criteria as established by the Atomic Energy
Commission.

                            FOREWORD

This report covers the activities of the Southwestern Radiological
Health Laboratory.  These activities are conducted in accordance with
a Memorandum of Understanding with the U. S. Atomic Energy Com-
mission.  In part, this memorandum authorizes the U.  S. Public Health
Service to investigate, assess,  record, and report the radiological
situation in  the public  areas  surrounding the Nevada Test Site, and to
inform and protect the public should an unacceptable radiological situ-
ation develop.
This report is the final report for Operation Niblick and supersedes
all previous reports issued by the Public Health Service for this series.
All future requests for data from Operation Niblick will be referenced
to this report.  It is neither  possible nor desirable to include in this
report every item of data obtained.  However,  summaries of all data
pertaining to exposures or contamination of people or of property  in
the off-site  areas have been  included.

                              Chapter 1
                           INTRODUCTION
Operation Niblick was a series of underground nuclear tests conducted
from July 1,  1963 through June 30, 1964, by the U. S. Atomic Energy
Commission (AEC) at their Nevada Test Site. As for past operations,
the U. S. Public Health Service (PHS) carried out a  program of radio-
logical surveillance of the public areas  off-site for the Operational Safety
Division of the AEC's Nevada Operations Office.  This surveillance is
conducted under a memorandum of understanding between the U. S.  Atomic
Energy Commission and the U. S.  Public Health Service.
The Off-Site Radiological Safety Program of the Southwestern Radiological
Health Laboratory (SWRHL) conducts its present program of radiological
monitoring and environmental  sampling in the off-site area surrounding
the restricted area enclosed by the Nevada Test Site, and the Nellis Air
Force Range.  This overall complex of the Nevada Test  Site (NTS) and
the Nellis Air Force Range (NAFR) includes the Nuclear Rocket Develop-
ment Station (NRDS) and the Tonopah Test Range (TTR) and for simplicity
will be called the test range complex throughout this report.

In order to carry out the assigned  program  of off-site surveillance,
the PHS  organized, equipped,  and trained aerial monitoring teams,
mobile ground monitors,  and provided for periodic sampling of air,
milk, water, vegetation,  film  badge  placement and evaluation of other
environmental factors.  A system of permanent,  continuous air
sampling stations  was maintained at  locations surrounding the test range
complex, and provisions were made  to supplement this network
with additional samplers if the need arose.  During the latter part of the

-------
Niblick series, additional sampling points were established for  regu-
larly scheduled milk and water  sample collection to augment the special
samples that were being collected.

A.   MEDICAL AND VETERINARIAN SERVICES
A PHS Medical Officer was available on short notice in the event any
cases of a medical nature arose as a result of the test series.  No
such cases were  brought to the  attention of the PHS and the services
of a Medical Officer were not required.
An  Army Veterinarian assigned to the NVOO, AEC, was available to
the  Public Health Service Off-Site Radiological Safety Program.  Vet-
erinarian services were also provided by a PHS Veterinarian.  Liaison
was maintained with livestock producers in the area and the program
of wildlife and cattle investigation was continued.

B.   PUBLIC RELATIONS
An  important part of off-site radiological safety activities is that of
public relations.   In their everyday contacts with residents of the off-
site area, PHS personnel express  their desire to speak to local groups
to explain the programs  at the Nevada Test Site and the role of the
Public Health Service  in them.
Talks and films covering elementary atomic physics and radiation effects
are given to school groups, while civic groups are offered talks and
films on atomic testing and the  safeguards  exercised to protect  the
public.
A number of off-site residents took part in the environmental sampling
program.  All routine sampling stations except Las Vegas were operated
by local citizens  and many more people wore film badge dosimeters.
This cooperation saved greatly  on  manpower requirements, and gave
the  individuals in a community a feeling of  participation in the PHS activ-
ities.

                   OPERATIONAL PROCEDURES

A.  EXTERNAL MEASUREMENTS
    1.  Ground Monitoring
    Each  monitor was equipped with the following monitoring instru-
    ments: an Eberline E-500B, a Precision Model 111 Standard
    "Scintillator", a Beckman MX-5,  and a Tracerlab AN/PDR TIB.
    The Eberline  E-500B has a range of 0 to 200 milliroentgens per
    hour  (mR/hr) beta-gamma over four linear scales with an external
    halogen filled GM tube detector and a 0 to  2000 mR/hr gamma
    only range from an internal Anton 302 tube detector.  The Precision
    Model 111  "Scintillator" is  used primarily for low level detection
    and provides for a range of 0 to 5 gamma mR/hr in six scales.
    The Beckman MX-5 instrument has a range of 0 to 20 mR/hr in
    three scales.   It is equipped with an external Geiger tube with a
    slide-open beta shield.  The Tracerlab AN/PDR TIB has a range
    of 0.05 to 50,000  mR/hr gamma in five scales.  This instrument
    employs  an air ionization chamber detector.  These instruments
    are accurate to +20% when readings are taken to two significant
    figures.
    2.  Dose Rate Recorders
    Eberline RM-11 dose rate recorders were placed at several sta-
    tions  around the test range  complex.  (See Figure  1, page 4).
    These recorders utilize a Geiger tube detector to document radia-
    tion levels at  specific locations. The instrument  operates on
    110V  AC and has a 0.01 to 100 mR/hr range.  Gamma dose rate
    is recorded on a 30-hour or 8-day  strip chart.  The instrument
    is accurate to +20%.

    3.  Aerial Cloud Tracking
    A PHS aerial monitoring team was available for each event in the
    Niblick series.  In the event of a release of radioactive material,
    this team,equipped with instruments identical to those used by
    ground monitors,  tracked the effluent.  Normally an Air Force
    U3-A aircraft and a PHS Aero-Commander were used in this
    tracking mission.
    Aerial cloud tracking is used as a tool to track and detect rela-
    tive radiation intensities and to indicate cloud position,  speed and
    direction.  The information thus  obtained is utilized  to position
    ground monitors to insure comprehensive ground coverage and
    subsequently better  surveillance.
    4.  Film Badges
    Approximately two hundred residents in the off-site area wore
    film badge dosimeters throughout the series.  The film badges
    were  changed each month and were processed by the Radiological
    Sciences Department, Reynolds Electrical and Engineering Co.,Inc.
    Approximately sixty-five  single badge and five  badge stations were
    also used to provide more complete coverage.

B.  ENVIRONMENTAL MEASUREMENTS
    1.  Air Samples
    During this series the PHS used General Metal Works high volume
    air samplers which  utilize glass  fiber prefilters and MSA charcoal
    cartridges.  The locations of these samplers are shown in Figure 1,
    page 4.  Twenty-four to thirty-four stations were operated routinely
    and several additional stations were established as required.  All
    air sample prefilters were returned to Las Vegas to be counted
    for gross beta activity with a thin window, large area gas flow

-------
proportional probe connected to a high speed sealer.  The system
has an efficiency of approximately 30% for  1. 5 Mev betas.  The
background for this system is 575 + 20 counts per minute.
Air samples were counted for gross beta activity as soon as  pos-
sible after collection,  and activity levels were computed at the
time of count for the purpose of screening samples  and delineating
the effluent trajectory.  These samples were then stored for five
days to allow natural activity to decay.  They were  recounted at
this time  and again seven days later.  Activity levels were then
recomputed to end of collection from these two  later counts.   Air
samples showing levels of activity significantly above natural back-
ground were recounted frequently to obtain a decay  curve.  The
curve obtained was then analyzed for the best fit to  the general
equation y=ax .   Based on an analysis of these decay curves, a
decay factor was determined.  This factor  was  then used to extrap-
olate activity to end of collection.
All charcoal cartridges were gamma scanned by placing  each car-
tridge  directly on a 4"x 4" Nal(Tl) crystal coupled to a 400-channel
pulse height analyzer  set to examine energies from 0 to  2 Mev.
The activity on the cartridge should represent gaseous fission
products only, especially the radioiodines.  Detection efficiency
for this geometry is 18% at 0. 53 Mev  (l 33I).  The minimum detect-
able activity for each iodine isotope is 200  picocuries total on the
cartridge.  Error estimates are such that values less  than 1 pico-
curie per cubic meter  of air collected (pCi/m3) are generally not
reported.  Since  it was not possible to define duration of effluent
passage at all locations, the reported values given  as pCi/m3
assume an average concentration over each entire sampling  period.

2.  Milk and Water Samples
After any release of radioactivity from the test range complex,
milk samples are collected from dairies (processing plants), pro-
ducing dairy farms, and farms  producing milk for their own con-
sumption.  Each sample was counted for 50 minutes.  All liquid
samples are analyzed for gamma-emitting isotopes in 3. 5 liter
inverted well aluminum beakers which are placed on top of a
4"x 4" Nal(Tl) crystal coupled to a 400-channel pulse height  ana-
lyzer.  The detection efficiency for the 0. 364 Mev photopeak of
1 31I is  5. 3%. A matrix technique is employed in computation to
compensate for  the interference due to the presence of other iso-
topes.  The input to this matrix is variable,  allowing for  the simul-
taneous determination of any eight nuclides for which detection
efficiencies and interference factors have been obtained.   Actual
computation is performed by an IBM 1620 computer.  No  attempt
was made to recount samples giving low positive values.   The
lower limit of detection for gamma emitters  in milk samples was
taken to be  20 picocuries per  liter (pCi/1) at the time of count,
and all  results below that value are reported as  <20 pCi/1  or not
detectable (ND).  The error associated with reported values is
+20 pCi/1 or 10%, whichever is greater.  All  reported  values are
extrapolated to  collection time.
Water samples  are analyzed for gross beta activity by  slow  evap-
oration of an aliquot in a 2" diameter  stainless steel planchet and
counting beta activity with a low-background counter.   Sr-90 -  Y-90
in equilibrium is used as a counting standard.  Due to the temper-
atures encountered in evaporation and fixing the residue to the
planchet, volatile radionuclides, such as iodine and cesium, and
dissolved gases will be missing from the sample at time of count.

-------
    This leads to gross beta results which would be low compared to
    the total radionuclide content of the sample.  Nevertheless,  the
    gross beta results are useful as a screening technique for samples
    containing unusually high amounts of radioactivity or for observing
    trends at a specific sampling location, and an observed increase
    in gross activity indicates a need for further analysis of the sam-
    ple.
    After gamma analysis of milk samples was  completed,  certain
    samples were analyzed for strontium-89 and 90.  After addition
    of strontium carrier, milk proteins are removed by trichloroacetic
    acid precipitation.  Following several purification steps, the puri-
    fied strontium is stored for at least one week to allow for  ingrowth
    of yttrium-90.  Strontium and yttrium are separated by nitric acid
    precipitation and both fractions are counted in a low-background
    beta counter.  The strontium-89 activity is  the calculated differ-
    ence between the total strontium activity and the strontium-90 (as
    yttrium-90 activity).

C.  SAFETY CRITERIA
Throughout  Operation Niblick, the criteria used for determining the
radiological hazard to the off-site population were those established
by the Atomic Energy Commission.
         "For planning weapons tests the criterion shall be 3.9
         Roentgens per year whole body exposure including any
         exposure from non-weapons test  activities (but excluding
         background and medical x-rays).  The criterion of 3.9
         Roentgens is in the definite context used in the past,  i.e. ,
         every reasonable effort should be made to keep the radia-
         tion exposures as low as possible,  but for planning pur-
         poses, if unanticipated yet credible circumstances could
         result in  estimated doses in excess of 3.9 Roentgens  per
         year, then the detonation should be postponed  until more
         favorable conditions prevail.  Also, to  avoid any given

-------
        community receiving unusually high exposures over a period
        of years, the guide shall be not more than 10 Roentgens in
        any consecutive 10 year period."
        "The Guides for radioactivity in air, water, milk and food-
        stuffs were not to exceed one-tenth the values listed in AEC
        Manual Chapter 0524, Standards for  Radiation Protection.
        These concentrations may be averaged over twelve consecu-
        tive months."*
The external exposure was estimated from  doses recorded by film
badges worn by off-site residents,  or from records of dose rate read-
ings taken in populated areas by PHS radiation monitors and by dose
rate recorders.  The external exposure excluded background and med-
ical exposures.
The concentrations of radioactivity in air and water, milk and food-
stuffs were averaged over  a period of one year.  The concentrations
in these media were determined from analysis of samples collected
from the off-site area. Data obtained during  the series of tests which
constituted Operation Niblick showed that the  guides were not exceeded.

D.  FIELD PROCEDURES
The working field unit of the PHS was the monitoring team composed
of one or two  people equipped with various  survey instruments,  sarrv-
pling apparatus,  tools and supplies.  Using dose rate meters or sur-
vey instruments, the teams monitored roads, areas, and locations
within the cloud trajectory. They set up additional air sampling sta-
tions and dose rate recorders, augmented routinely operating  stations
with charcoal cartridge collectors and collected other environmental
samples when required.  They also noted the  presence of people or farm
animals in areas not  usually inhabited, observed the condition of back
^(Quoted from a memorandum of Dr. Nathan H. Woodruff to James E.
 Reeves dated August  1, 1962.)

-------
roads and trails which might be needed for cloud tracking or surveil-
lance routes,  and checked infrequently traveled areas for radio recep-
tion and transmission.
During Operation Niblick, the PHS used aerial  monitoring teams to
augment its surveillance  program.  Before detonation of a nuclear
device,  the cloud tracking aircraft flew in a standby pattern within
sight of ground zero.  After detonation, if no visible venting  occurred,
low altitude passes were  made downwind of ground zero to determine
if gaseous  radioactive material could be detected.  After collapse of
the cavity, if no radiation had been detected by the aerial team and
ground telemetry indicated no release of radioactive material, the
aerial monitoring mission was terminated.  When a release did occur,
the aircraft made a series of passes at  several altitudes beginning
downwind of ground zero  and moving gradually  outward.  In this way
the team estimated the width and depth of the cloud and determined
its direction and speed of travel.  Measurements of radiation intensity
were made to  determine the distribution and magnitude of radioactive
material within the cloud, and to define concentration gradients if pos-
sible.  These  cloud tracking missions were terminated when the cloud
had dispersed or the activity it contained had dropped to  levels too low
for measurement, or when flying conditions necessitated termination
of the flight.

                             RESULTS







Table 1 lists the twenty-six announced underground events conducted



during Operation Niblick.  Two of these events released radioactivity



which was detected on the ground off-site.  The results of surveillance



for these events are summarized below.






A.  SUMMARY OF TWO EVENTS



    1.  Eagle



    The Eagle Event was an underground detonation conducted at



    0800 hours PST on December 12, 1963, by the Lawrence Radia-



    tion Laboratory.





    Some venting occurred immediately after detonation and continued



    for a few minutes until the cavity collapsed.  The released mate-



    rial moved southeast at about twelve knots.





        a.   Aerial and Ground Monitoring



        Four ground monitors, operating between Lathrop Wells and



        Indian Springs, detected no radiation intensities above back-



        ground.





        An aerial survey at 5000' MSL from Ground Zero to Ash



        Meadows at 1015 hours showed no radiation intensities  above



        background.




        b.   Air Sampling



        Table 2  contains the results of all air sample filters showing



        fresh fission products and Figure  2 shows off-site instrument



        locations.

    c.  Additional Environmental Sampling
    Sixteen milk samples from eleven locations were analyzed
    for specific gamma emitting isotopes.  No fresh fission pro-
    ducts were detected.  The results of all milk samples col-
    lected during the operation are listed in the Appendix.
    No water samples were collected for analyses in relation to
    this event.
2.  Pike
The Pike Event was an underground detonation conducted by the
Los Alamos Scientific Laboratory at 0802 hours PST on March  13,
1964.  Visible venting of gaseous and particulate material occur-
red immediately and continued for a few minutes until the cavity
collapsed.
    a.  Ground Monitoring
    Thirteen ground monitors recorded over five hundred and
    fifty individual dose rate measurements on the day of the
    event.  The maximum net gamma dose rate observed was
    5.9 mR/hr at Cactus Springs and the maximum net beta plus
    gamma observed was 40 mR/hr one mile  east of Cactus
    Springs.  The beta plus gamma measurement was taken at
    ground level.
    By the time the cloud had reached Las Vegas (about 1230 hours
    PST),  a dose rate of 0. 28 mR/hr net gamma was observed.
    On March 14, additional roads were monitored  and most roads
    monitored on March 13 were re-monitored.  Residual contam-
    ination was found from a few miles southwest of Las Vegas
    to Mercury.  Dose rate measurements of 0.01 to 0.07  mR/hr
    net gamma and 0.01 and 0.8 mR/hr net beta plus gamma were
                             15

-------
observed.  By March 15 residual contamination levels had
dropped to background in most areas.
A synopsis of ground monitoring results will be found in
Table 3 and the location of roads monitored and re-monitored
are shown in Figures 3 and 4 (pages 22 and 23).
b.   Aerial Cloud Tracking
Aerial cloud tracking dose rate readings from portable mon-
itoring instruments are not corrected for aircraft attenuation,
air attenuation, geometry, aircraft and instrument contamin-
ation, and the inherent inaccuracies of taking instrument
readings in a high speed aircraft while in a cloud for a  very
short time.  Therefore, these  measurements are  only rela-
tive in that they represent the changes in dose rate in flying
from uncontaminated areas (background) into and across the
effluent.  The data cannot be used to extrapolate ground con-
tamination or airborne radioactivity at ground level.
The U3-A aircraft crew first detected the radioactive cloud
from the Pike Event off-site at H+50 minutes.  At this time
the leading edge of the cloud was located about seven miles
northwest of Indian Springs and the cloud was moving on a
course that would take it over the Indian Springs-Cactus
Springs area. At  H+67  minutes a dose rate reading of
110 mR/hr was obtained at 7000 feet MSL five miles north-
west of Indian Springs  on a flight perpendicular  to the direc-
tion of movement of the cloud.  This was the maximum read-
ing obtained during the off-site cloud tracking mission.  From
H+85 minutes to H+123 minutes several passes were made in
the Indian Springs-Cactus Springs area as the cloud movement
down the Las Vegas Valley was documented.  The highest

reading obtained during this period was 6 mR/hr at H+92
minutes, one-half mile west of Cactus Springs at an altitude
of 3300 feet MSL.  The leading edge  of the cloud was seven
miles south of Indian Springs at H+115 minutes where, at an
altitude of 5000 feet MSL, the reading was 1. 5 mR/hr.  The
western edge of the cloud extended to approximately eight
miles west of Cactus Springs.
At H+139 minutes the U3-A mission was terminated because
of aircraft and instrument contamination and the plane landed
at Indian Springs Air Force Base. At 1130 PST, the same
crew took off from Indian Springs Air Force  Base  in a U6-A
aircraft with uncontaminated instruments.  A zig-zag pattern
was flown between Highway 95 and the Charleston Range to-
ward Las Vegas.  Readings from Indian Springs to the Lee
Canyon Road ranged between 0.6  mR/hr and  1.0 mR/hr.  A
pass 800 feet above the terrain from the Lee Canyon Road
toward Angel's Peak showed levels of activity in the 0. 8 to
1.0 mR/hr range.
By the time the cloud had reached the Charleston Park turn-
off, readings from 0.6 to 0.4 mR/hr were obtained.  Read-
ings taken on the  west side of the Charleston Range indicated
that the cloud was confined to the Las Vegas  Valley.  Upon
entering the Las Vegas Valley at  Red Rock Canyon at 1230
hours, readings increased to 0.6 mR/hr.  This mission was
terminated at Las Vegas at  1330 hours.
At 1430 hours an Aero-Commander took off from Thunder -
bird Field in Las Vegas carrying a Precision Model 111
"Scintillator" for cloud detection.  All readings were taken
at 5000 feet MSL.  The first leg of the flight  from Thunderbird
                        24

-------
Field to Blue Diamond was flown from 1430 to 1440 hours
with readings dropping from 0.016 mR/hr at Las Vegas to
0. 008 mR/hr over Blue Diamond and Red Rock Canyon.
Values of 0.016 mR/hr to 0.02 mR/hr were again encountered
about four miles west of Las Vegas at 1450 hours and these
values persisted to Sloan at 1455 hours.  Normal background
existed from Sloan to Jean and to Highway 95 enroute to
Boulder City.  From Highway  95 to Boulder City and from
Boulder1 City fifteen miles toward Searchlight, values of
0.016 to  0.025 mR/hr were observed. The southernmost
edge appeared to  be fifteen miles south of Boulder  City air-
port at 1515 hours.  Background readings were observed
from that point to Searchlight  over to  Lake Mohave and up to
willow Beach (1535 hours).  Levels slightly above background
were encountered halfway between Willow Beach and Boulder
City at 1540 hours, and from Boulder City to Eldorado Can-
yon at 1550 hours.  Just south of the Eldorado Canyon Road,
background was observed.  On the  return flight from Eldor-
ado Canyon, readings dropped to background at 1600 hours
over Railroad Pass and background persisted over Las Vegas
to Thunderbird Field.
In summary, the  western  edge of the  cloud appeared to be
three to four miles west of Las Vegas at 1440 hours  and the
southwestern edge over Sloan  at 1455  hours.  At 1550 hours
the southern edge had reached Eldorado Canyon, but the
eastern edge had  not passed the Colorado River by 1535 hours.
This delineation was drawn from readings barely discernible
above background and represent the greatest sensitivity which
could be  attained  with the  instrumentation employed.
                        25

-------
c.  Air
Only air samples taken at populated locations with gross beta
concentrations above normal background fluctuations, and/or
with fresh fission products on the charcoal cartridges are listed
in this report.  Air sampler locations are shown in Figures 5
and 6 (pages 27 and 28). Results are shown in Table 4,  (page 29).
d.  Water
No contamination of water supplies used for human consumption
was detected as a result of the Pike Event.  Water sampling
locations are shown in Figures 5 and 6.
e.  Milk
In addition to the routine milk sampling program carried out
by the Off-site Surveillance Section, four hundred and fifty
milk samples were collected after the Pike Event. All the
milk samples that were collected and analyzed as a result of the
Pike release are reported in Tables 1 and 2 of the Appendix.
Milk sampling locations are  shown in Figures 5 and 6.
No milk supplies from the commercial dairies sampled  showed
detectable amounts of fresh fission products.
f. Film Badges
Film badges collected following the Pike  Event showed no
exposures which  could be attributed to the release.   The
lower limit of these  badges  is 20 mR.
g.  Dose Rate Recorders
Graphical representation of recorder charts from the two
stations in the cloud path is shown in Figure 7 (page  31).

B.  SUMMARY OF OPERATION NIBLICK
    1.  Air Sampling
    Table 5 (page 33) shows the monthly averages of all permanent
    air sampling stations in operation during this  series.  When more
    than one sample was taken at a station during  a 24 hour period,
    the results were  averaged over the  entire 24 hour period.  The
    higher monthly average at Diablo during May was the result  of
    reactor test operations at the Nuclear Rocket Development Sta-
    tion.  The blank spaces in the table indicate that the sampling
    station was iiot yet established.
    2.  Film Badges
    Table 6 (page 34) contains a summary of film badge placement.
    Analysis of film badge  results indicates that no film badge expo-
    sures above the 20 mR detection limit occurred as a result of
    any one, or combination of, events  during this test series.   Film
    badge locations are shown in  Figure 8 (page 35).
    3.  Milk Sampling
    Table 7 (page 36) lists  all milk samples analyzed during the  series
    which contained fresh fission products, with the exception of those
    samples taken as a part of a special study by the SWRHL Bioen-
    vironmental Research Program following the  Pike Event.  The
    results of all the raw milk  samples collected  as a part of this
    study are listed in Table 2 of the Appendix.   For a discussion of
    these results consult "Dairy Farm Radioiodine Study following the
    Pike Event"  by Delbert S.  Barth and Joel G.  Veater, published
    as  SWRHL-14r and as AEC TID-21764.
    The only milk samples with positive results were collected fol-
    lowing the Pike Event.   The samples collected in Arizona and
    California with detectable concentrations of iodine isotopes,  were
                                 32

from farms.  No commercial dairy samples showed detectable
amounts of fresh fission products.  Complete tabulations of all
milk samples collected and analyzed during Operation Niblick are
shown  in the Appendix to this report.
4.   Water Sampling
Water  samples from surface and sub-surface supplies were col-
lected  and analyzed during the operation.  No contamination of
water used for human consumption occurred as a result of any one
or combination of events of Operation Niblick.
5.   Vegetation Sampling
Vegetation samples were collected only after the two previously
mentioned events.  The results from vegetation sampling are used
to determine the presence of fresh fission products in order to
delineate cloud passage and  to indicate possible areas for more
intensive sampling of other elements of the environment.  Since
vegetation sample results include so many parameters, they are
not used to assess exposure to people or animals in the off-site
area.

                  DISCUSSION AND CONCLUSIONS

A.  EXTERNAL EXPOSURES
The only event of the Operation Niblick series that produced off-site
radiation levels that were detectable on portable instruments was Pike.
Using the formula 5  x dose rate x hours since detonation,  the infinite
dose rate can be calculated for a given location.  This calculation is
made using the peak net gamma measurement on the day of the event.
The calculated infinite dose rate for Cactus Springs would be 85 mR,
at Indian Springs 25  mR, and 9 mR at Las Vegas.  These values may
be compared with the 150-200 mR annual exposure from natural back-
ground radiation.

B.  AIR SAMPLING
Radioiodine concentrations in air as determined by air sampling oper-
ations,  represented  only a small percentage of the allowable exposure
for populations as defined by the AEC.

C.  MILK  SAMPLING
The only radioiodine concentrations detected  in milk supplies occurred
after the Pike Event. All Las Vegas commercial dairies were sam-
pled daily and no radioiodine was detected. Other than those samples
taken for a special study in Las Vegas, Nevada, concentrations of l 31I
were found only at Yuma, Arizona and at Bard,  Blythe, and Winter-
haven, California.   The concentrations found at these locations were
well below the maximum permissible levels established by the  AEC.
                                 38

-------
D.  WATER SAMPLING
Water samples from potable and nonpotable supplies were sampled in
the downwind areas.  No contamination of water used for human con-
sumption was detected.

E.  CONCLUSION
Operation Niblick resulted in the addition of relatively minor amounts
of radioisotopes into the off-site area.  These amounts were well below
presently accepted maximum permissible exposures as defined by the
AEC Manual, Chapter 0524.

Note 1.   The numbers and letters in the ID columns in Tables  1 and 2
          are identification codes assigned by SWRHL.

Note 2.   In Table 2, the abbreviation G CH indicates that the cow was
          being fed freshly cut green feed (green chop).  The abbrevi-
          ation D FD indicates that the cow was on dry feed.  The  milk
          samples in Table 2 were collected for a special  investigation
          by the Bioenvironmental Research Program (see page 32).
