                                Preface
     Environmental Radiation Data (ERD) is compiled  and  distributed
quarterly  by the Office of Radiation Programs' Eastern Environmental
Radiation Facility (EERF), Montgomery,  Alabama,  and  contains  data
from  the  Environmental Radiation Ambient Monitoring System (ERAMS).
Data from 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.

     The radiochemical procedures used by the EERF in processing  the
ERAMS  samples  are  contained  in  Eastern  Environmental  Radiation
Facility Rad iochemi stry Procedures Manual.

            DATA - Reporting Rationale and Procedures
     In 1973, the U.S. Environmental Protection  Agency's  Office  of
Radiation   Programs,   established   the   Environmental   Radiation
Monitoring Systeni(ERAMS) to provide continuous, accurate, and  usable
environmental  radiation data to the public.  For completeness, ERAMS
data for all specific  radionuclide  analyses  are  reported  as  the
counting results indicate, whether the numbers are 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 has  no  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 many measurements produces a result
less than zero, this indicates a negative  bias  in  the  measurement
procedure.

          (1) Reported Valuejs
          Specific Analysejs ~ ^^ specific radionuclide analyses will
     be reported as the counting, results indicate, whether the number
     is  negative,  zero,  or  positive.   All  reported  values  are
     corrected for decay to the collection date.

-------
     Potassium  concentrations  are   determined   by   specific
activity analyses.

     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.

     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.  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 P r e c i pitation

     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.

     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/m^.   The  laboratory  obtained values are usually lower than the
field estimates due to the decay of naturally occuring  radionuclides
between the times of the two measurements.

     Precipitation samples are  collected  at  these  field  stations
collecting  air  filters.   These samples are also sent to EERF where
they are composited monthly for gamma scans,  tritium, and gross  beta
activity  measurements.   Plutonium-238, -239, and uranium-234, -235,
and -238 analyses are performed on samples which exceed  2  pCi/liter
gross alpha.

     Tables  2-4  present  the   monthly   average   gross   beta
concentrations in airborne particulates for January - March 1985

     Tables  5-7  present  the   monthly   average   gross   beta
concentration in precipitation January - March 1985.

     The tritium in precipitation samples for January - March 1985 at
the selected stations are shown in Table 8.
     A compilation of individual measurements is available  from  the
EPA, EERF, Montgomery, AL  36109.

             Plutonium and Uranium in Airborne Particulates

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

     Concentration of the specific isotopes of  plutonium-238,  -239,
and  uranium-234, -235, and -238 are determined by alpha spectroscopy
following chemical separation.   The volume of air represented by  the
quarterly composite ranges from 25,000 to 40,000 m^

     Plutonium and uranium in airborne particulates data for  January
-March 1984 are shown in Table 9.

     Table 9.1 contains the results of plutonium and uranium analyses
on  selected precipitation composite samples for 1984.   The composite
samples reflected in Table 9.1  are those ERAMS air stations that have
the longest history of continuous collection.

                               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  reprocessing,  weapons  tests,  and  research  and
defense  related  activities.   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.

                                 ERAMS
SECTION II.  Water Program

     The ERAMS water  program  provides  data  on  ambient  radiation
levels in the nation's rivers, streams and drinking water supplies.

                             Surface Water

     Quarterly grab samples are taken downstream  from  operating  or
future nuclear facilities at 58 stations.

     Surface water samples are analyzed  for  tritium  quarterly  and
specific  gamma  activity annually.  Tritium is a primary radioactive
pollutant  from  nuclear  power   plants   and   weapons   production
activities.

     Tritium concentrations are determined  by  liquid  scintillation
counting of distilled samples.  Gamma scans are performed annually to
determine levels of gamma emitting radionuclides.

     Tritium concentrations for surface water samples for  January  -
March 1985 are given in Table 10.

                             Drinking Water

     This program monitors ambient radiation levels in drinking water
at  78  sites.    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 the 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;  (c) radium-226 if the gross alpha exceeds  2  pCi/1  and
radium-228  if  the  radium-226  falls  between  3  and 5 pCi/1;  (d)
specific iodine-131  on  one  quarterly  sample  per  year  for  each
station;   and (e) an annual composite for plutonium-238 and -239 and
uranium-234, -235, and -238 for stations that demonstrate gross alpha
levels greater than 2 pCi/1.

     Tritium analyses are performed by scintillation counting of  the
distilled   samples.    Gross   beta  and  alpha  are  determined  by
evaporating an aliquot on a stainless steel  planchet  for  counting.
Radium-226   is  determined  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 1985 are shown in Table 11.

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  are  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.   The  program   consists   of
approximately  22  sites  representing  a  wide  geographic  coverage
throughout the country.* 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  three  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 approximately every
three  months.   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 1985 are shown in  Table
12.
     * Some of these sites may not return dosimeters each period  and
consequently the number of sites listed may vary slightly.

SECTION IV.  Milk Program

                            Pasteurized Milk

     This is a cooperative program with the Dairy and Lipid  Products
Branch,  Milk Sanitation Section, Food and Drug Administration.  Milk
is a  reliable  indicator  of  the  general  population's  intake  of
radionuclides  since  it  is consumed fresh 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  and  Puerto  Rico.   The  samples are
composited, according to production, from the  major  milk  suppliers
representing  more  than  80  percent of the milk consumed in a given
population center.

     The samples are analyzed for iodine-131, bariutn-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.   Strontiuro-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
1985 are shown in Tables 13 - 15.

     Strontium  values  from  regional  composite  samples  collected
January - March are shown in Table 16.

                           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.

     Data will be published as it becomes available.
                                  34
