                                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.

                            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.   All  reported  values  are
     corrected for decay to the collection date.
                                    vn

-------
     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.  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/rn^.    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.  Plutonium-238, -239, and uraniumr234,
"235, and *238 analyses are  performed  on  samples  which  exceed  2
pCi/liter gross alpha.

             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  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 gassing through the filters  normally  ranges  from
25,000 to 40,000 m3 for each quarterly composite.

     Plutonium and uranium in airborne particulates data for  October
A December 1983 will be published when 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  alsa  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  April
June 1984 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  April
June 1984 are shown in Table 10.

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

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 due  to  weapons  fallout,  reactor
operations,  etc.   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 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 April - June 1984 are shown in Table 11.
     * Some of these sites may not return dosimeters each period  and
consequently the number of sites listed may vary slightly.

     ** Starting  October,  1984,  this  program  will  change  to  a
quarterly cycle.

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*l40,
cesiunr"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  regio.ns  are  analyzed  for  strontium*-89  and
strontiunr*90.

     Iodine^-131, barium^l40, cesiunr-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  April  *  June
1984 are shown in Tables 12 - 14.

     Strontium values from regional composite samples collected April
- June 1984 are shown in Table 15.

                           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.
