                                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  (ERAMS),  and
similar networks operated by contributing  States,  Canada,  Mexico, and
the  Pan  American  Health  Organization  are  reported in (ERD) when
available.

     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.

     1.   Sampling  locations  are  selected   to    provide    optimal
population coverage while functioning to monitor fallout from nuclear
devices  and  other  forms  of  radioactive  contamination   of   the
environment.
                                                                /
     2.  The radiation analyses performed  on  these  samples  include
gross  alpha  and  gross  beta  levels, gamma  analyses  for fission
products and specific analyses  for  uranium,  plutonium,   strontium,
iodine,  radium,  krypton  and  tritium.  This monitoring effort also
serves  to  provide  ancillary  information  on releases   into   the
environment  from  stationary sources such as nuclear  power  reactors,
fuel fabrication  and  reprocessing  plants  and  natural   background
levels.

                            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  radionuclide
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.

                                 iii

-------
     MDL is defined as the 3 sigma error of  the  background.  A
tabulation of MDL'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

     Gross  beta  radioactivity  measurements  and  certain  specific
analyses  are performed on air particulates 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   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  diameter  synthetic fiber )  from  air  samplers
are  changed  twice weekly and field measurements  are made with a G-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/nP- 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 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 particulates for January - March 1982.

     Tables  5-7  present  the   monthly   average   gross   beta
concentration and any specific gamma concentrations for precipitation
samples  for  January  -  March  1982  A  compilation  of  individual
measurements is available from the EPA, EERF,  Montgomery, AL  36193.

     The tritium in precipitation samples  for  January - March 1982 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   the   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.

     Analyses of the composited filters consist of ashing, separating
by  liquid  ion  exchange,  and  coprecipitation  of the plutonium or
uranium.

     Concentration of the specific isotopes of  plutonium-238,   -239,
and uranium-234, -235, and -238 are determined by alpha spectroscopy.
The volume of air analyzed normally ranges from 25,000 to  40,000  m
for each quarterly composite.

     Plutonium and uranium in airborne particulates data for October
   December  1981 are shown for the 42 stations operating during this
period in Table 9.

     The plutonium and uranium analyses in precipitation for 1981 are
shown in Table 10.

                               Krypton-85

     Krypton-85 is a long-lived noble gas with a half  life  of  10.8
years.  It  is  released  into  the  atmosphere  by  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 annually and shipped to the
EERF where the krypton-85 is cryogenically separated and counted in a
liquid scintillation system.

     Results will be published when available.

                                 ERAMS
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.

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

     Tritium concentrations for surface water samples for  January  -
March 1982 are given in Table 11.

                             Drinking Water

     The drinking water program provides ambient radiation monitoring
relevant  to  the  effects  of  the  nuclear  power industry,  natural
environmental levels, 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  plutonium-238,  -239, uranium-234,  -235,  -238,
for  stations  which  demonstrate  gross alpha  levels greater than 2
pCi/1.

     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. Strontium-90 is  determined  by beta
counting a strontium carbonate precipitate isolated by ion exchange.

     The results of tritium in drinking water analyses for January
March 1982 are shown in Table 12.

     The annual alpha, beta, gamma, radium,  and  strontium analyses
for 1981 annual drinking water samples are shown in Table 13.

     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
                                17

-------
exposure  may exist in addition to the ingestion pathway. As an inert
gas, radon 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.

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   CaF2:Mn   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 January - March 1982 are shown in  Table
14.

SECTION IV. Milk Program

                            Pasteurized Milk

     This is a cooperative program of the EPA, ORP and the Dairy  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   radionuclide
concentrations and determine any long-term 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 a given population center.

     These  samples  are   analyzed   for   iodine-131,   barium-140,
cesium-137,  and  potassium.  All 65 samples are analyzed annually in
July for strontium-89, and strontium-90. Also, for the 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 strontium-89 and strontium-90.

     Iodine-131, barium-140, cesium-137 and potassium are  determined
by   gamma  spectral  analysis.  Strontium-89  and  strontium-90  are
determined by beta counting a total strontium precipitate  which  has
been chemically separated by ion-exchange.

     The values from the pasteurized milk samples for January - March
1982  are  shown  in  Tables  15 - 17. Strontium values from regional
composite samples collected January - March 1982 are shown  in  Table
18.
                            Tritium rn Milk

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

                           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  carbon-14  levels  in  the  food  chain
resulting from 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 1975 and May 1979 are reported in Tables 19 and 20 respectively.

                     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 areas to  provide  uniform  time
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 for the first and second  quarters  of  1982  are  shown  in
Tables 21-22.

                   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.

     Background Radiation Levels, Tritium, for  the  second  quarter,
1981, are shown in Table 23.
     Gross Radiation in Precipitation for the second  quarter, 1981,
is shown in Table 24.
     Gross Activity in Surface Water reported as pCi/1 for the second
quarter, 1981, is shown in Table 25.
     Gross Beta Activity in Air for the second quarter, 1981  is shown
in Table 26.
     SDWA (Safe Drinking Water Act) analyses for April, May and June,
1981, are shown in Tables 27, 28, and 29 respectively.
     SDWA Radiological analyses, second quarter recheck samples,  for
