                                Preface
     Environmental Radiation Data (ERD) is compiled  and  distributed
quarterly  by the Office of Radiation Programs' Eastern Environmental
Radiation  Facility  (EERF),  Montgomery,  Alabama.   Data  from  the
Environmental   Radiation  Ambient  Monitoring  System  (CRAMS)',,  and
similar networks operated by contributing States,  Canada,  Mexico,  and
the Pan American Health Organization are reported  in (ERD).
     ERAMS was established in  1973  by  the  U.   S.   Environmental
Protection Agency's Office of Radiation Programs (ORP).  The ERAMS is
comprised of nationwide sampling stations that provide air,   surface,
and   drinking  water  and  milk  samples  from which  environmental
radiation levels are derived.  The major emphasis  for ERAMS  is toward
identifying trends in the accumulation of long*lived radionuclides in
the environment.

     Sampling locations are selected to  provide  the  best   possible
combination  of  radiation  source  monitoring (such as surface water
downstream  from  a  nuclear  power  reactor)  and  wide   population
coverage.

     The radiation analyses performed on these samples include  gross
alpha and gross beta levels, as well as specific analyses for uranium
fuel cycle related radionuclides.  The latter category  includes  but
is  not limited to uranium, plutonium, iodine, and krypton,  which are
released into the environment from stationary sources such as nuclear
power reactors, fuel fabrication and reprocessing  plants.

                            DATA * Reporting Rationale and Procedures
     The Intent of EPA's Office of Radiation Programs in establishing
the  Environmental Radiation Ambient Monitoring System was to provide
continuous, accurate and usable environmental radiation data for  the
public.   Therefore,  new data reporting procedures were developed to
allow better interpretation of the data.  The most significant change
in  this  reporting  procedure  is  that  all  specific  radionoclide
analyses will be reported as the counting results  indicate,  whether
the number is negative, zero, or positive*

Reporting Rationale

     Frequently, concentrations of a  radionuclide  in  environmental
media  are close to zero.  When the actual concentration of a nuclide
is zero,  the  net  counting  results  should  statistically  show  a
distribution  of  negative  and  positive  numbers  about zero.  This
occurs when the background count is subtracted from  a  sample  which
has  only  background  activity.  Prior to July 1975, ERAMS data were
not reported numerically when the results were less than a  specified
reporting  level  or minimum detectable level.  The present reporting
procedure  allows  all  the  data  to  be  reported   and   evaluated
statistically  without  an  arbitrary  cutoff  of  small  or negative
numbers.  This approach will facilitate  estimates  of  bias  in  the
nuclide  analyses  and  will allow better evaluation of distributions
and trends in environmental data.

     When reviewing the  data  in  this  report,  caution  should  be
exercised  in  the  interpretation  of  individual  negative  values.
Obviously,  a  negative  activity  value  does  not   have   physical
significance.   Such  numbers,  however,  are  significant when taken
together with other observations which indicate that the  true  value
of  a  distribution  is  near  zero.   When  an  average  of  several
measurements produces a result  less  than  zero,  this  indicates  a
negative bias in the measurement procedure.

          (1) Reported Values

          Specific Analyses • All specific radionuclide analyses will
     be reported as the counting results indicate, whether the number
     is negative, zero, or positive.  Numerical values given  are  as
     of sample collection date.

          Gross Analyses - The actual value  of  gross  radioactivity
     measurements  will  be  reported,  unless the value is below the
     minimum detectable level (MDL) at the 2 sigma confidence  level,
     then < minimum detectable level will be reported.
                               m

-------
     MDL is defined as the 3, sigma error of the  background.    A
tabulation of HDL's is given in the following table.

     (2) Reported Error Terms

     Each  reported  ..value  for  specific   analyses   will   be
accompanied  by  a  counting  error  term  at  the 2 sigma (95%)
confidence interval.  Potassium concentrations are determined by
specific  activity analyses.  Error terms are therefore reported
as counting errors.  At the very low  levels  characteristic  of
most   ERAMS'   measurements,  counting  error  is  the  greatest
contributor to overall error.

     (3) Significant Figures

     All reported values will be rounded to no more  than  three
significant  figures.   The  last  significant  figure  will  be
increased by one if the figure following  is  five  or  greater,
otherwise it is left unchanged.

     (4) Reporting Levels

     The reporting units, smallest increments for reporting,  and
minimum detectable-levels for each isotope are shown in table 1.
Smallest increments  are  sometimes  considerably  smaller  than
minimum   detectable  amounts  to  avoid  truncation  errors  in
averaging.

     (5) Averages

     Averages will.be calculated along  with  appropriate  error
terms  in  an  annual  summary  and  analysis of ERAMS data.   In
calculating  these  averages,  all  values  of  individual  data
including  negative numbers will be utilized.  Averages will not
be included in ERD quarterly reports.

SECTION I.  Air Program

                Airborne Particulates and Precipitation

     Cross  beta  radioactivity  measurements  and  certain  specific
analyses  are performed on air participates and precipitation samples
as indicator measurements in assessing the general (national)  impact
of all contributing sources on environmental levels of radiation.

     Airborne particulates are collected  continuously  at  67  field
stations representing wide geographic coverage, including present and
potential sources of environmental radioactivity.  Sampling sites are
located  throughout the United States, Virgin Islands, and the Panama
Canal.

     Filters (10-cm charcoal impregnated cellulose) from air samplers
are  changed  twice weekly and field measurements are made with a C-M
survey meter at 5 hours and 29 hours after collection  to  allow  for
radon  and  thoron  daughter  product  decay.   Field  estimates  are
reported to appropriate EPA officials by telephone or mail  depending
on the activity levels found.

     The filters-are sent to EERF for more sensitive  analyses  in  a
low  background  beta  counter.   Gamma  scans  are  performed on all
filters  showing  laboratory  gross  beta  counts  greater   than   1
pCi/m^.    The   lower  gross beta  values  reported  for  laboratory
measurements are largely due to  the  decay  of  radionuclides  which
occurred  between  the  times  of  the field estimates and laboratory
measurements.

     Precipitation samples are collected at  the  22  field  stations
where air filters are collected.  These samples are also sent to EERF
where they are composited monthly for tritium,  gross  beta  activity
measurements and gamma scans.

     These locations also  correspond  to  airborne  particulate  and
drinking  water  sampling  locations selected for plutonium analyses.
Plutonium-238, -239, and uranium-234, -235,  and  -238  analyses  are
performed  annually on precipitation samples collected during March -
May.

-------
     Tables  2-4  present  the   monthly   average   gross   beta
concentrations in airborne participates for July - September 1981.

     Tables  5-7  present  the   monthly   average   gross   beta
concentration and any specific gamma concentrations for precipitation
samples for July -  September  1981.   A  compilation  of  individual
measurements is available from the EPA, EERF, Montgomery, AL  36193.

     The tritium in  precipitation  samples for July - September 1981
at the selected stations are shown in Table 8.

             Plutonium and Uranium  in Airborne Particulates

     Environmental radiation  levels  of   plutonium  and  uranium  are
determined  by  the  analyses-  of   quarterly  composite  samples (air.
filters)  collected  from   the1  continuously   operating   airborne
particulate  samplers.  The number,  of: continuously operating; stations
is being increased from the original! 22!  will,  eventually  number*  67
when all. equipment is> operational..

         ."    '         '  •       Krypton-85

     Krypton-85 is a long-lived noble gas with a half  life  of   10.8
years.   It  is  released   into  the  atmosphere  hy  nuclear reactor
operations,  fuel  fabrication,  fuel   reprocessing,   and   nuclear
detonations.   Krypton-85   also  occurs naturally in minor quantities
primarily from the neutron capture of stable krypton-84  as  well  as
spontaneous   fission   and   neutron-induced   fission  of  uranium.
Monitoring of krypton-85 in the  atmosphere  has  been  conducted  to
identify and establish baseline levels and long-term trends.

     Krypton-85  analysis   began  in   January   1973   with    sample
collections  and  analyses being performed for 12 sampling locations.
These locations were selected to provide atmospheric coverage of  the
United  States  with  considerations  being given to the proximity to
fuel reprocessing  plants,  nuclear  reactors,  and  wide  geographic
coverage.

     Dry compressed air samples,  collected  at  each  location,  are
purchased  from  commercial air suppliers semiannually, and shipped to
the EERF where the krypton-85 is cryogenically separated and   counted
in a liquid scintillation  system.

     Data for January *  June 1976 were reported in ERD 8.
Note.  •- The recovery tracer required  for  the  analysis  of  these
samples  is  currently  unavailable.  When the tracer is available or
new methodology developed, the samples received after June 1976  will
be analyzed and reported in this report series.

SECTION II.  Water Program

     The ERAMS water  program  provides  ambient  radiation  data  to
assess  the  effects  of  the  nuclear  power  industry,   the natural
radiation environment, and other  nuclear  sources  on  the  nation's
rivers, streams and drinking water supplies.

                             Surface Water

     Grab  samples  are  taken  quarterly  at  58  stations   located
downstream from operating or future nuclear facilities.

     Surface water monitoring consists of tritium analyses  quarterly
and  gamma  scans  annually.   Tritium  is  the  primary   radioactive
pollutant from nuclear power plants,  therefore,  all  nuclear  power
plants that are operating or scheduled for operation through 1980 are
being monitored.

     Tritium concentrations are determined  by  liquid  scintillation
counting of distilled samples,  pamma scans are performed annually to
determine if there is a buildup of other contaminants.

     Tritium concentrations for surface  water  samples   for  July
September 1981 are given in Table 10.

                             Drinking Water

     The drinking water program provides ambient radiation monitoring
relevant  to  the  effects  of  the  nuclear  power industry,  natural
environmental insult, and other pertinent sources.   These data  serve
to assess trends and anomalies in concentrations,  and to compare with
standards set forth in the EPA  "National  Interim  Primary  Drinking
Water   Regulations."  These  regulations  provide  for  approval  of
supplies when the combined radium-226 and radium-228  levels  do  not
exceed  5  pCi/1,  when the gross alpha (excluding radon, and uranium)
levels do not exceed 15 pCi/1, when  tritium  levels  do  not   exceed
20,000 pCi/1, when the strontium*90 levels do not  exceed 8 pCi/1, and
when the gross beta levels do not exceed 50 pCi/1.

     Grab samples are taken  at  78  sites  which   are  either  major
population centers or selected nuclear facility environs.

     The analyses include (a) tritium on a quarterly basis (b)  gross
alpha,  gross  beta,  and  strontium-90  on  annual composites (gamma
analyses are performed if the gross beta activity  is greater than  10
pCi/1;   radium«226 analyses are performed if the  gross alpha exceeds
2 pCi/1;  and radium-228 analyses are  performed  if  the  radium-226
activity  falls  between  3  and  5 pCi/1) (c) specific iodine-131 is
performed on one quarterly sample per year for each  station  (d)  an
annual composite for plutoniumfc238, -239, uranium-234, -235, -238, on
22  selected  sampling  locations   corresponding    to   continuously
operating air particulate stations.

     Tritium analyses are performed by scintillation counting of  the
distilled  samples,  gross  beta,  and  gross alpha by evaporating an
aliquot on stainless steel planchets for counting,  and radium-226  by
the standard emanation technique.  Strontiumf90 is determined  by beta
counting a strontium carbonate precipitate isolated by ion exchange.

     The results of tritium in drinking water  analyses  for  July
September 1981 are shown in Table 11.

     Iodine-131 concentration in drinking water for July  -  December
1981 is shown in Table 12.
     All samples were  taken  as  either  a  single  grab  sample  or
composite samples taken over 12 to 14 days.
                      Radon-222 in Drinking Water
     Radon-222 in drinking water has  previously  been  considered  a
source  of radiation exposure primarily from an ingestion standpoint.
The Office of Radiation Programs (ORP)  of  the  U.S.   Environmental
Protection  Agency  (EPA) is investigating radon in water supplies to
evaluate  the  possibility  that  a  major  pathway  from .inhalation
exposure may exist in addition to the ingestion pathway.  As an inert
                                 16

-------
gas, radori is not chemically bound to the water and consequently  can
be  released  during  any  operation  that aerates or agitates water.
Depending  upon  the  initial  concentration  of  radon   in   water,
significant quantities of radon could be released in a home or to the
general environment.

     To determine the scope of this  potential  problem,   a  national
ground  water  sampling  program  has  been  initiated by the Eastern
Environmental Radiation Facility  (EERF)  to  obtain  data  on  radon
concentrations  in  water  supplies throughout the country.  Sampling
kits have been assembled by.-EERF and  distributed  to  various  state
health  departments.  The kit is designed so that state personnel can
collect samples from potable water supplies and  ship  them,  without
loss of radon other than radioactive decay, to EERF for analysis.

     The selection of water supplies to be sampled is handled by  two
separate methods.  Method 1 in which each state collects samples from
all groundwater supplies serving at least 1000 people and Method 2 in
which  the choice of sampling locations and the number of supplies to
be sampled is left to the discretion of  the  state  programs.   Each
state  is  asked  to obtain a representative sampling of ground water
supplies within its boundaries.  The extent of the  sampling  efforts
and  how  representative the data are for a given state is determined
primarily by the amount of time each state devotes to the program.

     The concentrations of radon in water are determined at the  EERF
by  liquid  scintillation  counting.  The limit of detection for this
technique using a 50-minute count and a 10-ml sample is 0.16  pCi  or
16 pci/1.

     The sampling kits are being provided to the various states on  a
rotating  schedule.   This  schedule  is  designed  to cover the U.S.
within approximately two years.  As data from each state are compiled
they will be published in ERD.

     Summaries  of  the  data  from  Idaho,  Kentucky,  Montana,  New
Hampshire, New York, Ohio and Oregon are shown in Tables 13 - 19.

SECTION III.  External Gamma Ambient Monitoring Program

     The external gamma monitoring program, which  began  in  October
1978,  provides  a  continuous  measurement of ambient gamma exposure
rates, including cosmic, at selected sites throughout the continental
United  States.   Data  from  this  program  will be used to evaluate
fluctuations in natural background due to variations in environmental
conditions  and  to  provide  a  means  of monitoring any significant
increases in ambient gamma levels due  to  weapons  fallout,  reactor
operations,   etc.    Initially,   the   program   will   consist  of
approximately  22  sites  representing  a  wide  geographic  coverage
throughout  the  country.   Hopefully,  at some later date additional
sites will be added to the program.  Although  exposure  measurements
at  these  few  sites  are  not  totally representative of nationwide
exposures, they will be indicative of national trends.

     The  monitoring  program  utilizes   CaFoiMn   thermoluminescent
dosimeters  (TLD's).   These  dosimeters  are  commercially available
glass-bulb type dosimeters with energy compensating shields.  A group
of  four  TLD's  is  located at each station or site.  Dosimeters are
annealed by the station operator prior to positioning in  the  field.
The  dosimeters  are  returned  to EERF for readout on an approximate
one-month cycle.  Several dosimeters  are  annealed  by  the  station
operator  as  controls and returned with the exposed field dosimeters
to correct for any exposures accumulated during shipment.

     Results from the period July  1981  through  September 1981  are
shown in Table 20.

SECTION IV".  Milk Program

                            Pasteurized Milk

     This is a cooperative program of the EPA, ORP and the Pairy  and
Lipid  Products  Branch,  Milk  Sanitation  Section,   Food  and  Drug
Administration.   Milk  is  a  reliable  indicator  of  the   general
populations  intake  of radionuclides since it is consumed by a large
segment of the population and contains several  of  the  biologically
important  contaminants  resulting  from  environmental releases from
nuclear activities.  A primary function of this program is to  obtain
reliable   monitoring   data   relative   to   current   radiqnuclide
concentrations and determine any longrterm trends.

     Monthly samples are collected at 65 sampling sites with  one  or
more located in each state, Puerto Rico, and the Panama Canal.  These
are .composite samples representing more than 80 percent of  the  milk:
consumed in major population centers.

     These  samples  are   analyzed   for   iodine-131,   barium*140,
cesium-137,  and  potassium.  All 65 samples are analyzed annually in
July for strontiuro-89, and strontiunr90.  Also, for tjie  first  month
of  the  three  quarters  beginning  January,  April  and October, 10
regional composite samples of milk made up  from  the  states  within
each   of   EPA's  10  regions  are  analyzed  for  sprontium-89  and
strontium*90.

     Iodine-131, barium^lAO, cesium-137 and potassium are  determined
by  gamma  spectral  analysis.   Strontium-89  and  strontium-90  are
determined by beta counting a total sjtrontium precipitate  which  has
been chemically separated by ion-exchange.

     The  values  from  the  pasteurized  milk  samples  for  July  ,-
September  1981  are shown in Tables 21 - 23.  Strontium .89 and 90 in
pasteurized milk from all stations for July  through  September  1981
are shown in Table 24.
                            Tritium ^£ Milk

     It was previously proposed to analyze all 65  milk  samples  for
tritium in the aqueous and organic phases, on an annual basis (09 the
April  sample).   The  EERF  is  currently   evaluating   alternative
analytical  techniques  anticipating  that  these analyses will begin
during the coming year.

                     Plutonium and Uranium in Milk

     Ten milk sampling sites near plutonium handling facilities,  plus
2  sites chosen for background information, are analyzed annually for
piiitonium and uranium.  Analytical techniques approximate those  used
for air filters.

     Only plutonium analyses were performed on the 1974 samples,   hut
due to increased emphasis on levels of natural radioactivity;  uranium
analyses were included for 1975 • 1976  samples.   Data  for  samples
collected April 1978 were reported in ERD 14.

                           Iodine-129 in Milk

     Thesis analyses were designed to assess environmental  levels  of
iodine-129  around  nuclear  fuel  reprocessing  facilities;   Annual
samples  collected  from  Montgomery,  Alabama  (background);    Idaho
Falls,   Idaho;    Chicago;   Illinois;    Buffalo,  New  York;   and
Charleston, South Carolina;  are analyzed for iodine-129  and  stable
iodine-127.  Results for 1978 were reported in ERD 17;

                           Carbon-14 in Milk

     Nine  stations,  chosen  for  wide  geographical   distribution,
contribute  milk  samples  for  annual analysis for carbon-14.  These
samples have  monitored  the  carbbri-14  leveils  in  the  food  chain
resulting fr6in nuclear testing;

     Analysis  consists  of  combusting  the  samples  and  measuring
released carbon dioxide through liquid scintillation.

     The results of carbon-14 analysis on  samples  collected  during
May 1974 were repbrted in ERD Report 2, September 1975.

SECTION V.  Human Bone Program
     The Human Bone  Program  (formerly  Human  Bone  Network)  began
operation in 1961 to obtain data on the concentration of strontium-90
in man by age and geographical region.   The  target  population  for
this network is comprised of children and young adults up to 25 years
of age.  The bone specimens  were  limited  to  accident  victims  or
persons  who had died of'an acute disease process that was not likely
to impair bone metabolism.

     The following are operational characteristics of this program:

     All samples are composited according  to  'age  and  geographical
locations.

     Strontium-90, plutonium*238 and -239, and calcium  analyses  are
performed annually on the composite samples.

     No additional bone samples were procured past  FY-75.   Analysis
of samples on hand will be completed and results evaluated'.

SECTION VI.  Pan American Health Organization (PAHO)
             Air and Milk Program
     An agreement was made in  1962  with  the  Pan  American  Health
Organization (PAHO) to develop a collaborative program for furnishing
assistance to health  authorities  in  the  Americas  for  developing
programs  of  radiological  health.   The  agreement provided limited
quantities of essential equipment on a loan basis to PAHO which  were
needed  to  establish  surveillance  programs,  and also provided the
requisite laboratory services for analysis of air particulates, milk,
water,  and  other  samples.   Technical advice was given on research
designs for radiological health programs.

     Analyses prior to January 1977 included the following:

     Milk  -4   monthly   samples   analyzed   for   gamma"emitting
radionuclides, strontium-89, -90.

     Air particulates - 12 stations with daily samples  analyzed  for
gross beta.

     Beginning January 1, 1977, the PAHO Air Program was discontinued
and milk sampling was reduced to quarterly collection.

     The PAHO programs are included organizationally as an  ancillary
function of the ERAMS.

     Results of the Pan American surface air particulate analyses for
October » December 1976 were reported in ERD f).

     Results of the Pan American milk quarterly analyses for  October
•» December 1978 were reported'in ERD 16.

                                                DATA - STATE AGENCIES
                       Radiologic Health Section
                    California Department of Health
California Air Sampling Program
     The Radiologic Health Section of the  California  Department  of
Health  with the assistance of several cooperating agencies, maintains
a statewide air sampling-network.  One  of  the  objectives  of  this
program.is to measure and evaluate the contribution of fixed effluent
sources to particulate activity in the air.,  Data from  air , samplers
placed   in   proximity  to  nuclear  facilities  are  compared  with
information obtained from similar equipment in communities  close  to
the facilities and at several "background" or control stations.

     Airborne particles are .collected by a continuous sampling of air
filtered through a 47 millimeter membrane filter, 0.8 micrometer pore
size, using a Cast air pump that provides an average sampling rate of
40 liters per minute.  Air volumes are measured with a direct reading
gas meter.  Filters are replaced when approximately 300 cubic  meters
of  air  are  collected,  i.e.,  on a weekly or semi-weekly schedule.
Charcoal cartridges mounted behind  the  filters  at  10  of  the  18
stations are replaced weekly.

     All air samples are sent  to  the  Department's  Sanitation  and
Radiation  Laboratory,  where the filters are analyzed for gross beta
radioactivity  72 • hours  after  collection.    Alpha   activity   is
determined  weekly  on  ashed  filters.   Gamma  spectroscopy  and an
analysis for strontium-89 and strontium-90 are normally performed  on
quarterly  composites  from each location.  Immediate gamma scans are
run on any samples for  which  abnormal  gross  activity  values  are
observed.  Charcoal cartridges are analyzed for radioiodines by gamma
spectroscopy as soon as received.

     Data will be published as received.
                                   47

Radionuclides in California Milk
     Although milk is only one of the sources of  dietary  intake  of
environmental  radioactivity, it is the food item that is most useful
as an indicator of the general population's  intake  of  radionuclide
contaminants resulting from environmental releases.  The objective of
this milk sampling  network  is  to  obtain  information  on  current
radionuclide   concentrations   and   long-term  trends.   From  this
information the need for further investigation or  corrective  public
Health action can be determined.

     The California network consists of 10 stations, six of which are
from  dairies  close  to major nuclear facilities, and the other four
represent  controls,  composited  from  local  miIksheds  in  similar
geographic locations from the plants.  Samples are obtained quarterly
and analyzed immediately upon receipt.* Results are reported as pCi/1
with  an  error  of  two  standard  deviations.
     Data will be published as received;
*Radionuclides  are  determined  by  gamma  spectroscopy,  with   thfe
exception  of  iodine-131,  which  is  analyzed  in  accordance  with
procedures specified in USNRC Regulatory Guide 4.3, and  strontium-89
and strontium-90, which are determined by radiochemical technique.

                     Radiological Health Laboratory
                     Indiana State Board of Health
Indiana Milk Analysis Program
     In order to evaluate the fallout on  Indiana  pasturelands,   the
State  has  implemented  a  program whereby monthly milk samples  from
five  geographical  areas  are  sent  to  the   Radiological   Health
Laboratory  of  the State Board of Health.  The milk in these samples
is bottled on the same date in all five
from pasture to the lab.

     Once in the laboratory, the milk  is  first  analyzed  by  gamma
spectroscopy    for    iodine-131,    barium-140,   cesium-137,   and
potassium-40.  A one gallon sample is analyzed on a 3" x  3"  Nal(Tl)
scintillation  crystal  for  4800  seconds.   A  background sample of
48,000 seconds is also run.  The data are analyzed to give pCi/1   for
each radionuclide.

     A quarterly composite sample is saved and run  for  strontium-89
and -90 by ion exchange method.

     Data will be published as received.

                      Radiological Health Division
                   State Hygienic Laboratory of Iowa
Iowa Water Sampling Program
     The  radiological  Health  Division  of   the   State   Hygienic
Laboratory  of  Iowa  with  the assistance of the State Department of
Environmental Quality (DEQ) maintains  a  state-wide  water  sampling
program   of   community   drinking   waters,   surface   waters  and
precipitation.  All analyses with the  exception  of  the  sequential
Ra-226,  -228  analyses  are performed according to "Standard Methods
for the Examination of Water  and  Wastewater",  14th  edition.   The
sequential  analyses  for  radiums are performed according to the EPA
publication, EPA-600/4-75-008, "Interim Radiochemical Methodology for
Drinking Water."

     The  drinking  water  samples  are  collected  by  DEQ  regional
personnel  and  sent  to the State Hygienic Laboratory where they are
preserved with HC1.  These waters are analyzed for  gross  alpha  and
gross beta radioactivity as a screening process.  Subsequent analyses
for Ra-226, Ra-228, Sr-90  are  performed  if  screening  levels  are
exceeded.   Radium  levels  are  of  primary concern in Iowa drinking
waters as those levels are elevated in deep geologic aquifers  within
the state.

     Surface waters are collected  at  eleven  sites  throughout  the
state  with site selection being determined by proximity upstream and
downstream  to  nuclear  power  plants  in  Iowa  or   those   plants
discharging  into  rivers  which  are  natural borders with adjoining
states.  Gross  alpha,  gross  beta,  and  tritium  are  the  routine
radionuclide  analyses  for  these samples.  Strontium is of interest
when gross beta screening levels are exceeded or if  nuclear  weapons
testing  necessitates  monitoring  to  determine  its  impact  on the
environment.

     Gross Beta Activity in Air  for the fourth quarter, 1980, is  in
Table 25.
     Background Radiation Levels, Tritium, are in Table 26.
     Gross Radiation in  Precipitation for  the fourth quarter, 1980,
is in Table 27.
     Cross  Activity in  Surface Water  reported as  pCi/1 for fourth
quarter, 1980, is in Table 28.
     SDWA (Safe  Drinking  Water  Act) analyses for October, November
and December, 1980 are shown in Tables 29, 30 and 31 respectively.
     DEQ  Mineral Samples  for October,  November and December, 1980,
are shown in Tables 32, 33 and 34 respectively.

     The  results for the first  three quarters of 1981 are available
but because of space  restrictions they  are not included in this re-
port. They will be published in the forthcoming reports.
