                                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 the 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.

     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.   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   provides    ancillary
information  on  natural  background  levels and on releases into the
environment from stationary sources such as nuclear  power  reactors,
fuel fabrication facilities, 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  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.

                                  vi

-------
     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.

                    AMBIENT MONITORING SYSTEM (ERAMS)
SECTION I.  Air Program

                Airborne Partlculates 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/nH-  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 participates for October - December 1983.

     Tables  5-7  present  the   monthly   average   gross   beta
concentration in precipitation October - December 1983.

     The tritium in precipitation samples for October -  December 1983
at the selected stations are shown in Table 8.

    Plutonium and Uranium iii Airborne Particulates and Precipitation

     Environmental radiation levels  of  plutonium  and  uranium  are
determined  by  the  analyses  of  quarterly  composite  samples (air
filters)  collected  from  the  67  continuously  operating  airborne
particulate samplers.

     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  m3
for each quarterly composite.

     Table 8.1 contains the results of plutonium and uranium analyses
performed on selected precipitation composite samples.

     Plutonium and uranium in airborne particulates data for July
September 1983 will be published when they become available.

                               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.

     The Kr-85 results will be published when they are available.

SECTION II. Water Program

     The ERAMS water  program  provides  ambient   radiation  data  to
assess   the  effects  of  nuclear  fallout,   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  October
December 1983 are given in Table 9.

                             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,  strontium-90  and  gamma  on annual composites.
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 October  -
December 1983 are shown in Table 10.

     Iodine-131 concentration in drinking water for 1983 is shown  in
Table 11.

     All samples were  taken  as  either  a  single  grab  sample  or
composite samples taken over 12 to 14 days.

                      Radon-222 in Drinking Water
     For all practical purposes,   the  Radon-222  in  Drinking  Water
Program  has  been  completed.   Only  a  few samples occasionally are
received for analysis. The Radon-222 and other natural  radioactivity
results will be the subject of  several reports,  including Methods jind
Results of EPA^s Study of Radon in Drinking Water by  T.   R.  .Horton,
Nationwide Occurrence  of_  Radon  and  Other Natural Radioactivity in
Public Water  Supplies  by T.  R.   Horton  and  The  occurrence   of
Radioactivity  jLn Public Water  Supplies in the_ United States  by C. T.
Hess, J. Michel, T. R. Horton,  H.  M. Prichard, and  W.  A. Coniglio.
Copies of these reports will be available from the —
                U. S. Environmental Protection Agency
                    Office of Radiation Programs
              Eastern Environmental Radiation Facility
                        Montgomery, AL 36193
     The Radon-222 in Drinking Water section will be  terminated as  of
this  issue  but  it  will  be  reinstated   if  sufficient  results are
accumulated in the future.

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   CaFo.'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 October-  December  1983  are  shown  in
Table 12.

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  October^
December 1983 are shown in Tables 13 - 15.

     Strontium  values  from  regional  composite  samples  collected
October * December 1983 are shown in Table 16.

                            Tritium ±n 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.

     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.

     Data will be published as it becomes available.

     RADIOLOGICAL MONITORING OF THE CHICAGO AREA WATERWAYS
                     January - December 1980

     The three river systems of the greater Chicago area —

Chicago, Calumet, and Des Plaines — are under the jurisdiction

of the Metropolitan Sanitary District of Greater Chicago  (Dis-

trict) .  They comprise 170 miles  (273.6 Km) of waterways.  The

District maintains a monitoring program of the water quality

of these systems with regards to the standards established by

the Illinois Pollution Control Board (IPCB) as well as for the

purpose of detecting any changes with respect to the water

quality of the past and future years.  The analyses for total

alpha and beta radioactivity have been a part of this overall

monitoring program of the river systems since mid-1975.  The

program is an ongoing activity of the District and this report

presents the results for 1980.

     Samples for radioactivity were collected in HCl-containing

plastic bottles once a month at a predetermined number of loca-

tions:  17 on the Chicago River, 12 on the Calumet River, and

18 on the Des Plaines River.

     A 500 ml aliquot of a water sample was evaporated to

approximately 20 ml, transferred into an evaporating dish,

evaporated to dryness, and flamed until no vapors were given off.

The remaining solids were scraped loose, ground with a pestle,

and then transferred into a counting planchet.  A couple of drops
                              37

-------
of carbon tetrachloride were added to help evenly spread the



solids.  Subsequently, the samples were counted 100 minutes



for total alpha and 100 minutes for total beta activity by



the use of a Beckman Widebeta II proportional counter which



was previously calibrated with radium-226 and cesium-137,



respectively, for total alpha and total beta determinations.



     The results of the determinations for the year 1980 are



tabulated in Tables 1-3 in terms of the number of samples



analyzed, the yearly low, high, and average (x)  total alpha



and total beta concentration for each sampling location; the



reported error is given by



                      e = 1.96 S-



where S- is the standard error of the average net activity.
