          In response to the Marine Protection, Research and Sanctuaries
Act of 1972, as amended (Public Law 92-532), the Environmental Protection
Agency (EPA) developed regulations and criteria to control ocean disposal
of waste materials, including low-level radioactive wastes (LLW) .  In
1981, the EPA Office of Radiation Programs and the Food and Drug
Administration (FDA) began monitoring the concentrations of radioactivity
in seafoods commercially available from marketplaces that are near
previously used LLW disposal sites.

          Between 1946 and 1970, the United States authorized ocean
disposal for LLW.  The EPA has determined that approximately 112,000 LLW
containers were disposed off the Atlantic and Pacific coasts, primarily
at the following locations:  (1) near the Farallon Islands off the coast
of California; (2) at two deep-ocean sites east of the Delaware,
Maryland, and Virginia (DELMARVA) peninsula; and (3)  in Massachusetts
Bay.  Accordingly, for this EPA/FDA radionuclide monitoring study,
seafood samples were collected from San Francisco, Atlantic City and
Boston, each of which is near one of the major U.S. ocean disposal
locations for LLW.

          This report presents the results of EPA and FDA radionuclide
analyses for all seafood samples collected.  The data show that the
radioactivity levels for man-made nuclides in the samples were found to
be within normally expected environmental background (ambient)  ranges.
There is no indication that previous U.S. ocean disposals of LLW have
resulted in contamination of commercially available seafoods.

          The Agency invites all readers of this report to send any
comments or suggestions to Mr. David E. Janes, Director, Analysis and
Support Division, Office of Radiation/programs (ANR-461), Environmental
Protection Agency, Washington, D.C.,/2p460.

                                 PREFACE
          This report presents the results of a monitoring program,
conducted in 1981 and 1982, by the Environmental Protection Agency  (EPA)
and the Food and Drug Administration  (FDA).  Its purpose was to measure
concentrations of man-made radionuclides  in seafoods to determine effects
from previous U.S. ocean disposals of low-level radioactive wastes
(LLW).  Commercially-marketed seafood samples were collected from Boston,
Massachusetts, Atlantic City, New Jersey  and San Francisco, California.
Each of these cities is near a previously-used U.S. ocean disposal  site
for LLW.

          Seafood samples were collected  from commercial fishing boats in
Boston between September 1981 and November 1982, in Atlantic City between
September 1981 and May 1982, and in San Francisco between October 1981
and May 1982.  Samples were obtained as the boats returned from fishing
trips near the previously-used LLW disposal sites.  Fish samples
collected from Boston included Atlantic cod, Winter flounder, Haddock,
Red hake and Pollock.  Cusk eels were also collected.  Conger eels
and Tilefishes were collected from Atlantic City.  Fish samples from
San Francisco included Dover sole, Lingcod, Pacific hake, Pacific red
snapper, Sablefish, and Thornyhead.

          All samples were analyzed for radioactivity by the EPA Eastern
Environmental Radiation Facility (EERF) in Montgomery, Alabama, and by
the FDA Winchester Engineering and Analytical Center in Winchester,
Massachusetts.  This report presents the  radioanalytical data from EERF
and WEAC.  Tables 6, 7 and 8 show the results from EERF for cesium-137,
plutonium-238 and -239, and strontium-90.  The WEAC data for cesium,
plutonium and strontium are contained in  Tables 9, 10 and 11.  Appendices
A, B and C provide a listing for all analytical results, both man-made
and natural radionuclides, completed by EERF.

          All EERF analytical results for plutonium-239 and strontium-90
yielded values below the minimum detectable level (MDL) for each
radionuclide, as given in Table 5.  Two analyses for cesium-137 provided
results equal to or above the MDL, but are consistent with previously
reported ambient data.  Two analyses for  plutonium-238 provided data
above both the MDL and ambient levels, but a large error term associated
with each of these analyses discounts their validity.

          The WEAC reported no detectable activity for plutonium-239 or
strontium-90 in the samples analyzed.  Measureable levels were reported
in twelve of thirty-seven samples analyzed for cesium -137, and are
consistent with cesium values in fish reported previously.

          The data obtained during this monitoring program shows that the
concentrations of man-made radioactivity  in seafoods sampled are below
levels of public health concern.  The data is considered to be of normal
background level, attributable to global  fallout over the oceans.

                I.  HISTORICAL AND REGULATORY PERSPECTIVE
          Since World War II,  the  increased use of radioactive materials
in the United States has created substantial volumes of low-level
radioactive waste  (LLW) materials.  LLW are routinely generated by
nuclear power facilities, commercial manufacturing processes, military
and civilian research programs, university laboratories and medical
facilities.  LLW are generally defined as all radioactive waste materials
not directly resulting from the reprocessing of spent nuclear reactor
fuel, and usually contain such radionuclides as cobalt, strontium,
plutonium and cesium.  Small quantities of source materials, such as
uranium, may also be included.  Additionally, LLW frequently include
laboratory equipment, tools, clothing or other items that became
contaminated by contact with radioactive substances.

          The United States began  disposing of LLW in 1946 at ocean
locations authorized by the Atomic Energy Commission (ABC), as well as
by shallow burial on government-owned land.  For ocean disposal, the AEC
licensed private companies to  package, transport and dispose of LLW.
Packaging was normally accomplished by placing the LLW in containers for
insertion into steel drums that were to be capped on both ends with
concrete or by mixing the LLW  directly into concrete used to fill steel
drums.  In most cases, 55-gallon drums were used.  After waste encasement
and concrete solidification were completed, the drums were transported to
designated ocean disposal sites where the drums were then allowed to
free-fall through the water column onto the sea floor.  By 1963, most LLW
disposals in the oceans ended  because the AEC began to issue licenses for
the use of newly authorized, commercially-operated land disposal sites,
which were found to be more economically attractive to contract
disposers.  Some at-sea LLW disposal licenses did remain in effect
through the late 1960's, but in 1970 the United States terminated all
ocean disposals of radioactive waste materials.

          In 1972, the U.S. Congress enacted the Marine Protection,
Research, and Sanctuaries Act  (Public Law 92-532) which authorized the
Environmental Protection Agency (EPA) to regulate all ocean disposal of
waste materials, including any radioactive wastes.  The Act directed the
EPA to determine that any type of  waste disposals will not unreasonably
degrade or endanger human health or the marine environment.  The EPA was
also directed to establish and apply criteria to review and evaluate
waste disposal permit applications.  The Act further directed that
comprehensive, continuing monitoring for effects from waste disposals in
the oceans be coordinated between  the Department of Commerce's, National
Oceanic and Atmospheric Administration (NOAA)  and the EPA.

-------
           In 1973,  the United States  ratified the 1972 London Dumping
 Convention (LOG)  which prohibited, as does U.S. Public Law 92-532,  any
 ocean disposal of high-level radioactive wastes (HLW), as defined by the
 International Atomic Energy Agency (IAEA).  Future ocean disposals  of  LLW
 were permitted,  but only  under the controlled conditions stipulated by
 the LOG.

           The EPA Office  of Radiation Programs began a series of
 environmental studies at  formerly used LLW disposal sites in 1974.  Four
 of the known U.S. ocean disposal locations were surveyed to obtain  data
 to support the development of regulations and criteria to control any
 future disposals.   Pacific Ocean studies, at 900 meter and 1700 meter
 sites within the AEC-designated Farallon Islands LLW disposal area,
 were conducted in 1974 and 1975 (DYER, 1976) and in 1977 (SCHELL, 1980) .
 Atlantic  Ocean studies, at 2800 meter and 3800 meter LLW disposal sites,
 were carried out in 1974  and 1975 (DYER, 1976), 1976 and 1978 (REISH,
 1983)  and (HANSELMAN, 1983).

           The EPA issued  regulations  and criteria for ocean disposal of
 waste materials in  1977,  stipulating  that radioactive materials be
 containerized to prevent  dispersion of radionuclides into ocean waters,
 and that  the containers remain intact in the environment until the
 radioactivity within them decays to innocuous levels.

           During the late 1970's and  early 1980's, public and
 Congressional interest about effects  from previous U.S. ocean disposals
 of LLW increased.   Specific public health concerns were expressed because
 of the potential for LLW  leakage from containers that were disposed
 previously off the  coasts of California and the DELMARVA (Delaware,
 Maryland  and Virginia) peninsula, and in Massachusetts Bay.  In response
 to these  concerns,  the EPA initiated  additional projects to determine  the
 potential for public health and environmental effects from previous U.S.
 ocean  disposals  of  LLW.

           In 1981,  the EPA reviewed available LLW ocean disposal records
 to more precisely determine the total extent of actual disposals.   The
 records that EPA obtained consisted primarily of licenses issued by the
 ABC  to private contractors, and log books from contractor-operated
 national  laboratories supported by the AEC.  From these licenses and log
 books, the EPA  identified intended or actual dates of disposal, approxi-
 mate quantities of LLW materials prepared for disposal, quantities  of
 waste  transported to disposal sites,   and planned or actual navigational
 disposal coordinates.   The general nature of LLW materials for disposal
 and the estimated radioactivity at the time of packaging were usually,
 but not always, provided.   The records did not contain specific infor-
mation about  the types of isotopes or other items that were within  each
 individual container.   In designating ocean LLW disposal areas, the AEC
had sometimes provided a  single set of navigational coordinates; thereby
potentially concentrating disposals within a relatively specific sea
floor area.  In other  instances, however, the AEC had designated boundary
limits for LLW disposal areas,  allowing for potentially broader sea floor
disposal areas.

-------
          In 1981, EPA determined that approximately 112,000 LLW
containers were disposed at sea off the U.S. coasts between 1946 and
1970, and that the total radioactivity amounted to approximately 120,000
curies at the times of disposal.  Twenty-nine ocean locations were
identified as having received LLW.  Four of these areas received the
majority of wastes and are identified in Figure 1 as one area near the
Farallon Islands in the Pacific Ocean, two nearby areas in the Atlantic
Ocean, and one in Massachusetts Bay.  The Farallon Islands LLW disposal
area, which includes two disposal sites at depths of 900 meters and 1700
meters, received approximately 14,700 curies (98 percent) of the total
radioactivity disposed of by the U.S. in the Pacific Ocean.  In the
Atlantic Ocean, LLW dispoals occurred at both a 2800 meter and a 3800
meter site.  These sites together received approximately 102,500 curies
(97 percent) of all the radioactivity disposed off the U.S. east coast.
The Massachusetts Bay LLW disposal area received about 2 percent of the
Atlantic Ocean total (CURTIS, 1984).

          Also in 1981, at the request of EPA and in response to
Congressional interest in ocean monitoring activities, NOAA began to
collect samples of biota and sediment for EPA from Massachusetts Bay
during routine NOAA monitoring program surveys.  NOAA also conducted a
side scan sonar survey at three sites in the Bay during 1981, as
preliminary support to an EPA radiological monitoring survey in the Bay
in 1982 (LOCKWOOD, 1982) and (CURTIS, 1984).  These sites had been
designated by the ABC for disposal of LLW in the 1940's and 1950's.

          During 1981 the EPA also requested assistance from the Food and
Drug Administration (FDA), specifically to conduct public health
monitoring as outlined in an EPA/NOAA draft programmatic monitoring
plan.  A portion of that plan pertained to measuring radioactivity in
seafoods commercially available from marketplaces in cities near the
major U.,S. ocean LLW disposal areas, since the contamination of seafoods
is the only significant pathway by which humans could be affected by
previous U.S. ocean disposals of LLW.  The FDA has, for many years,
maintained a national Total Diet Studies Compliance Program to monitor
levels of radioactivity in a variety of foods.   Samples are routinely
collected by FDA scientists throughout the country and sent to the
Winchester Engineering and Analytical Center (WEAC) in Winchester,
Massachusetts for radionuclide analyses.  In response to the EPA's
request, the FDA began collecting commercially-marketed fish samples from
San Francisco, Atlantic City, and Boston during the fall of 1981 for
analysis by both the WEAC and the EPA Eastern Environmental Radiation
Facility (EERF) in Montgomery, Alabama.

          The remainder of this report describes the EPA/FDA Marketplace
Seafood Sampling and Analysis Program, conducted during 1981 and 1982.
The collection of samples, the results of radionuclide analyses, and
conclusions from the study are presented in Sections II, III and TV,
respectively.  Appendices A, B and C contain complete computerized data
results from EERF radionuclide analyses of samples collected in Boston,
Atlantic City, and San Francisco.

                    II.  MARKETPLACE SEAFOOD SAMPLING
          During the summer of 1981, EPA and FDA scientists and program
managers met to discuss potential cooperative efforts related to public
health monitoring.  The EPA was specifically concerned with determining
whether the levels of radioactivity in seafoods routinely consumed by the
public, from fish catches near the previously-used U.S. LLW ocean
disposal sites, posed any real or potential public health problems.

          The FDA had previously conducted a study in which twelve
commercial fish samples were analyzed for radioactivity (see Table 1).
These samples were collected for the FDA near the Farallon Islands LLW
disposal site by fishermen from Point St. George, California in 1978 and
1980.  The FDA, based upon the data from their analyses of those fish
samples and the results of previous EPA studies at major U.S. LLW
disposal sites, concluded that previous U.S. ocean disposals of LLW were
not giving rise to radiation levels in commercial fish that are above
background levels of radioactivity in the oceans and, thus, of no public
health significance.  The FDA did, however, recognize that the available
data on radioactivity levels in commercial fish species were limited and
believed that additional sampling was therefore warranted (STROUBE,
1984) .  Accordingly, the FDA agreed to begin a limited Marketplace
Seafood Sampling and Analysis Program for EPA in the fall of 1981 to
analyze commercially-marketed seafoods for selected radionuclides.

          In August 1981, three of the FDA district offices (Boston,
Newark and San Francisco) set up a program to collect twelve samples of
edible fish; six samples from each district during the fall of 1981 and
six more samples during the spring of 1982.  Samples of marketable fish,
those most likely to be eaten by the public and caught by commercial
fishermen near the major U.S. sites for ocean disaposal of LLW, were to
be collected from Boston, Atlantic City and San Francisco.  FDA personnel
were to determine which commercial fishing boats would be harvesting near
the disposal sites during the Marketplace Seafood Monitoring Program, and
to obtain representative samples from these boats when they returned to
port.  Collectors were to particularly ensure that the dockside
collections were made from only those species of fish collected near
LLW disposal sites.

          The FDA collection procedures from the fishing boats were
designed to provide standardized sampling within each district.  The
seafoods collected provided no less than twenty (20)  pounds of edible
portions per species.  Bottom-feeding fish were designated as the samples
of choice since these would most likely provide any evidence of
radioactivity migrating into the marine environment from the LLW
containers in the disposal sites.  Three different bottom-feeding species
were to be acquired from each district collection.  When bottom-feeders
were not be a part of the fishing boat harvests, samples of pelagic
feeders (nonmigratory and/or migratory)  or shellfish were to be collected.

          Thirty-seven seafood  sanples were actually collected  from
Boston, Atlantic City and San Francisco fishermen.  The  species
obtained are listed and briefly discussed below.  Common name
identifications were provided by  the FDA district personnel collecting
the samples.  The brief summary about each type of sample collected was
compiled from information contained in  (GATES, 1974),  (GCTSHALL,  1987),
(McCLANE, 1978), (MILLER, 1972),  (MUSICK, 1979), and (RAY, 1956)  and
from  ichthyologists at the California Academy of Sciences Aquarium in
San Francisco.

2.1   Samples Collected from Boston

          Atlantic Cod (Gadus morhua) is a common commercial catch and
popular sport fishery species that is generally abundant in New England
waters from mid-October to April.  These cod are known to either
migrate extensively or remain fairly constant in a given area.  Adults
are commonly caught from 60 to  1,500 feet, and feed primarily on
bottom-dwelling invertebrates and smaller demersal fishes.  The younger
specimens are normally found bottom-feeding in snallower waters than
adults, after an early portion  of the life cycle is spent feeding on
copepods and small crustaceans  in surface waters.  Most  commercial New
England catches are in the six  to twelve pound range.

          Cusk eels (family Ophidiidae)  bear a resemblance to true eels
and to eelpount fishes (family  Zoarcidae).  These are basically small
(commonlly about one-foot long  at maturity), burrowing-type marine
animals, but they can attain lengths to'approximately five feet.  They
are generally caught in bottom-trawls, as were the samples collected
during this monitoring program.

          Haddock (Melanogrammus aeglefinus)  is an important commercial
species from the cod family of  fishes.  It is commonly caught at depths
ranging from 150 to 450 feet where it feeds primarily on bottom-
dwelling invertebrates.  Average catch sizes are one to  two feet and
one to five pounds.  Some seasonal migration occurs northward in the
spring and to the south during  the fall.

          Pollock/Boston Blackfish (Pollachius virens)  is another
member of the cod fish family.  It feeds more in surface waters than
does  the Atlantic Cod or Haddock, but not exclusively.   Typical catch
sizes are one to two feet, four to fifteen
pounds.  It is a popular sport  fishery catch.

          Red Hake (Urophycis chuss)  is an important commercial,
bottom-feeding fish that is generally caught by line-trawl fishing at
night.  It ranges from the shallower waters to depths of 1,800  feet,
feeding on shrimps, amphipods, squids and other fish.  Spawning usually
occurs in the Massachusetts Bay area during June and July.  Normal
catch sizes are two to five pounds.

-------
           Winter Flounder (Pseudopleuronectes americanus)  is a very
 common, right-eyed,  shallow-water flounder ranging to depths of 400
 feet.  They generally move in groups,  searching for food,  from deeper
 to shallower waters  during the fall and offshore in spring,  but do not
 usually migrate very far from spawning areas.  Average sizes are one to
 one and one-half feet, and one to two  pounds.

 2.2  Samples Collected from Atlantic City

           Tilefish (Lopholatilus chamaeleonticeps)  is a benthic fish,
 normally found at depths from 250 to 1,000 feet in outer continental
 shelf and upper continental  slope waters.   It is primarily a sport
 fishery catch,  that  is especially fished for  in the Hudson Canyon area
 by New York and New  Jersey party boats.   These fish can attain sizes to
 about fifty pounds,  although the average catch is approximately three
 feet long and weighs about thirty pounds.   They feed on invertebrates
 and smaller fish.

           Conger eels (Conger oceanicus)  are  true eels that  range in
 size from four  to six feet and are commonly found in the shallower
 depths on the continental shelf from Cape Cod to North Carolina.

 2.3  Samples Collected from  San Francisco

           Dover Sole (Microstomus pacif icus)  is a very common,  benthic
 fish in the waters off central California.  They are an important
 commercial catch.  These right-eyed flounders are normally caught by
 trawling the bottom  at depths between  100  and 3,000 feet.  Some
 specimens attain lengths of  two and one-half  feet,  weighing  ten pounds.
 They feed upon  brittle stars,  molluscs,  polychaetes and crustaceans.
 Short migrations along the coastline are  common;  but there are  no
 indications of  extensive seasonal inshore/offshore  migrations.

           Lingcods (Ophiodon elongatus)  are bottom-feeders fished
 by  commercial and  sport fishermen.   They  are  found  at depths to
 approximately 400  feet.   Commercial catches frequently range up to fifty
 and sixty pound  sizes,  sometimes  to seventy pounds.   Common  catches are
 about three  feet and  thirty  pounds.

           Pacific  Hake/Butterfish (Herluceius productus) is  very
 abundant  in  sport  and commercial  fish catches.   They are generally
 larger  (sizes to three  feet  are common) than  the  Atlantic  Ocean cod
 family of  fishes and are commonly found  in the  waters off  central
California to depths of  3,000  feet.  They normally  feed on smaller
 fishes and squids.

          Pacific Red Snapper  (Sebastes sp.)  is  a bottom-dwelling,
 invertebrate and fish-eating member  of the Scorpaenidae (Rockfish)
family that attains lengths  to about two feet.  They are commonly
found to depths of approximately  600 feet, and  sought after  by  sport
and commercial fishermen.

-------
          Sablefish/Black Cod (Anoplopoma fimbria) is an important
commercial catch in central California waters to approximately 600 feet
deep.  Commonly about three feet in length when caught, they feed on
various fishes, crustaceans and tunicates.  They are often consumed as
a smoked delicacy.

          Thornyhead/Hard Head (Sebastolobus sp.) is another  ery
important commercial catch in central California waters.  Primarily
benthic, they feed upon crustaceans and other fishes.  The short-spined
species (Sebastolobus alascanus) is common at depths from approximately
100 to over 5,000 feet.  Common lengths are approximately two and
one-half feet.  The long-spined species (Sebastolobus altivelis)  is not
commonly harvested, as most catches are at depths between 1,000 and
5,000 feet.  Common sizes are one to one and one-half feet.
     All thirty-seven samples were forwarded to the FDA's Winchester
Engineering and Analytical Center (WEAC) in Massachusetts, where a
twenty-pound blended homogenate was prepared from the edible portion of
each sample.  One-half of this homogenate was retained by WEAC; the
other half was sent to the EPA Eastern Environmental Radiation Facility
(EERF)  in Alabama.  Thus, independent radionuclide analyses were
performed on each half of the prepared samples.

     The information in Tables 2, 3, and 4 shows when and approximately
where each sample was collected.  Sample identification numbers used by
each radiation laboratory are also listed.

                    III.   MARKETPLACE SEAFOOD ANALYSES
3.1  Analytical Procedures

          The WEAC retained one-half  (ten pounds) of  the blended
homogenate prepared from the edible fish portion of each seafood sample
collected by the three FDA districts.  WEAC analyzed  each sample for
gross gamma activity, cesium-137,  iodine-131, barium-140, and
strontium-90.  Six of the twelve samples received from each FDA district
were also analyzed for plutonium-239.  The analytical methods used are
described in references to this report (BARATTA, 1969 and 1977) and (PHS,
1967).  These well-established, analytical methods have been routinely
used by WEAC for several thousand  samples in the FDA  Radionuclides in
Foods Compliance Program.  WEAC detection limits are  10.0 pCi/kg for
cesium-137, iodine-131 and barium-140; 2.0 pCi/kg for strontium-90T and
0.1 pCi/kg for plutonium-239.  The FDA routinely reports an analysis as
non-detectable when the two-sigma  error is greater than the measured
value of activity.

          The EERF received a ten-pound portion of the blended homogenate
from WEAC for each of the samples  collected during this Marketplace
Seafood Sampling and Analysis Program.  All samples were analyzed for
gross gamma, alpha and beta activity.  In addition, individual analyses
were conducted for the following radionuclides:  plutonium-238,
plutonium-239, strontium-90, lead-210, polonium-210,  radium-226,
thorium-227, thorium-228, thorium-230, thorium-232, uranium-234,
uranium-235 and uranium-238.  Standard sample preparation and specific
analytical procedures were used by EERF (LIEBERMAN, 1984).  Measured
values were reported on a wet-weight basis.

          NOTE:  The minimum detectable level (MDL) used by EERF is
defined as the minimum value of environmental radioactivity that may be
confidently detected, and its reliability is less than a five percent
chance for errors of the first kind (determining that activity is present
when it is not) and of the second  kind (failing to determine that
activity is present when it is).   The MDL estimates the minimum activity
that will yield a large enough signal to enable analysts to confidently
state that something other than ambient variations were detected.  At
EERF, the MDL is typically and predominately due to the instrumental
counting error and is set equal to the two-sigma counting error for
specific analyses.  The MDL is in  no way used to adjust measurement
values.  Table 5 provides the EERF MDL for each radionuclide identified
in the seafood samples collected during this Marketplace Seafood Sampling
and Analysis Program

3.2  Analytical Results

          A complete listing of radionuclide analytical data is presented
in the Appendix to this report for all samples received by EERF during
the Marketplace Seafood Monitoring Program.  Appendices A, B, and C
contain the data for those samples collected by the FDA from Boston,
Atlantic City and San Francisco, respectively.  The EERF data includes
specific analyses for indicated radionuclides, as well as gross alpha and
gross beta activity.  Data are presented for both natural and man-made
radionuclides.  The discussion of analytical results in Section IV is,
however, limited to the activity levels observed for man-made
radionuclides measured in the seafoods collected during this monitoring
program, because the purpose of the study was to determine potential
effects from ocean disposal of man-made radionuclides associated with
LLW.  The natural radionuclide data are presented for information only.

          A careful examination of the data in the Appendices shows that
many of the specific analyses performed by EERF are reported at levels
below the MDL's listed in Table 5.  This is in keeping with guidelines
established by the EERF quality assurance program to provide both
accurate and usable environmental radiation data, and to allow for
statistical evaluation of the analytical results.  Thus, except for gamma
spectrometry data, all EERF radionuclide analytical results are reported
as the counting results indicate, whether the numbers are negative, zero,
positive, above or below the MDL.  When analyzing for specific
radionuclides in environmental samples, activity levels are frequently
found to be close to zero.  When the actual concentration of a
radionuclide in a sample is determined to be zero, the net counting
statistics should statistically show a distribution of negative and
positive numbers about zero.  This occurs when background detection
counts are subtracted from a sample that only contains very low levels of
radiation, resulting in the observation of negative number or zero values
by the analyst.  Reporting data in this format allows all the data to be
presented and evaluated statistically without an arbitrary cutoff of
small or negative numbers.  This reporting approach facilitates estimates
of bias in the nuclide analyses and allows for better evaluation of
distribution and trends in environmental data.  Thus, when reviewing the
data presented in this report, caution should be exercised in the
interpretation of individual negative or zero values.  Obviously a
negative value has no individual significance, but such numbers are
significant when examined together with other observations of
radionuclide concentrations indicating that the real distribution of
values is near zero.  Accordingly, activity values for the radionuclides
analyzed by EERF during the Marketplace Seafood Monitoring Program are
presented as follows:

                   Gross Alpha and Beta Analyses  Data are reported  in
Appendices A, B and C  as actual values of gross radioactivity.  When
measured concentrations are below the MDL for these analyses, at the
2-sigma confidence level, the MDL is reported.

-------
                   Specific Analyses  Activity  levels are  reported  in
 the Tables and Appendices as negative, zero or positive numbers  (except
 for gamma spectrum analyses which are essentially qualitative  rather  than
 quantitative measurements).  Numerical values account  for  radioactive
 decay  subsequent to the sample collection date.   Activity  levels that are
 below  the MDL represent background counting data  and the activity is
 reported less confidently than for those levels of activity  that are
 equal  to or greater than the MDL, as can be seen  when  comparing  the
 2-sigma counting error to the reported activity.

                   Error Terms  Are provided for each analysis and
 refer  to the counting term error at the 2-sigma (95 %) confidence level.
 Thus,  error terms are reported as counting errors.

          Tables 6, 7A-C, and 8A-C summarize the  EERF  man-made
 radionuclide analytical results that are contained in  the  Appendices.
 Tables 9, 10, and 11 provide the results for WEAC radionuclide analyses.
 A generalized comparison between the EERF and WEAC analytical  results can
 be made by referring to the data in Tables 6, 7A-C, 8A-C,  9, 10  and 11,
 which  also contain cross-referenced sample numbers.

          An actual comparison of specific numerical results from the
 EERF and WEAC radionuclide analyses is not routinely possible, however.
 This is primarily due to the distinct differences in the sensitivity
 levels (MDLs) that exists between each laboratory for  analyzing  the
 same radionuclides in samples.  At EERF, for example,  the  MDL  for
 cesium-137 is 25 pCi/kg, 1.5 pCi/kg for plutonium-239  and  20 pCi/kg
 for strontium-90.  At WEAC the MDLs are:  10 pCi/kg for cesium-137,
 0.1 pCi/kg for plutonium-239 and 2 pCi/kg for strontium-90.  These
 differences in sensitivity of analysis result in  opposite  approaches
 to the reporting of data by EERF and WEAC, as follows:

              o    EERF provided numerical results for every
 plutonium-239 and strontium-90 analysis, whether  or not the activity
 level  for that radionuclide in the sample was below, equal to  or  above
 the stated MDL.  Thus, the EERF data includes negative, zero and positive
 activity levels as explained in the preceeding pages of this report.
 EERF also reported positive cesium-137 activity levels (below, equal  to
 or above the MDL) obtained from gamma spectroscopy analyses of the
 samples.  No analytical results were reported by  EERF when the gamma
 analysis did not detect Cs-137, or other gamma nuclides, as can  be seen
 by reviewing the Appendices.

              o    WEAC, in reporting its data, provided numerical
 analytical results only when the activity level of a radionuclide in  a
 sample exceeded (was above)  the MDL.  Thus, in comparing data, note that
most of the WEAC analyses for cesium-137, and those that were  actually
performed for plutonium-239 and strontium-90, are reported here  as "ND"
 (not detected)  values.  Note also that WEAC did not analyze for  Pu-239
and/or Sr-90 in twenty-eight of the thirty-seven  samples collected.

                       IV.   SUMMARY AND CONCLUSIONS
4.1  Discussion of Analytical Results

          A total of thirty-seven seafood samples were collected during
the 1981-1982 Environmental Protection Agency  (EPA) and Food & Drug
Administration (FDA) Marketplace Seafood Monitoring Program.  The FDA
Winchester Analytical and Engineering Center (WEAC) prepared a
twenty-pound blended homogenate from the edible portions of each seafood
sample collected by the FDA from Atlantic City, Boston and San Francisco
fishermen.  Each sample consisted of a sufficient number of seafood
samples to prepare the twenty-pound homogenate.  One-half of the blended
homogenate sample was retained by the WEAC; the other half was shipped,
frozen, to the EPA Eastern Environmental Radiation Facility (EERF).  The
WEAC analyzed all thirty-seven of its homogenate samples for cesium-137,
barium-140, and iodine-131.  Nineteen of the samples were also analyzed
for plutonium-239 and strontium-90.  The EERF, having split four of the
homogenates obtained from the WEAC, completed  forty-one analyses each for
cesium-137, plutonium-238, plutonium-239, and  strontium-90.  In addition,
the EERF also completed forty-one analyses for each of the natural
radionuclides identified in the Appendices.  Tables 6-11, in Section III
of this report, list the results from the EERF analyses for man-made
radionuclides, and all of the analyses completed by the WEAC.  Tables 12
and 13, in this Section, provide a summary of  the data presented in
Tables 6-11.

          Table 12 pertains only to the data from Tables 6, 7A-C, and
8A-C.  The results from the EERF for cesium, plutonium, and strontium are
grouped into activity-level categories.  It is noteworthy that only four
of the 164 analyses (less than 2.5%) yielded results equal to or
exceeding the EERF minimum detectable levels (MDL); two each for
cesium-137 and plutonium-238.  All analyses for plutonium-239 and
strontium-90 provided results less than MDL.

          As shown in Table 12, the EERF detected cesium-137 at a level
equal to or greater than MDL (25 pCi/kg wet weight) in only two of
forty-one analyses.  Both were from samples collected from Boston
fishermen.  In Table 6 the cesium-137 activity in a Cusk eel sample is
reported as 31 (+ 11) pCi/kg, exceeding the MDL.  In an Atlantic cod
sample the activity reported is 25 (+ 14) pCi/kg, equalling the MDL.
One could add the error-range to the reported  activity levels and obtain
a maximum possible activity for each sample, which would be 42 and 39
pCi/kg respectively.  This worst case approach to reporting data would
put the activity levels from these two samples in or below the lower
portion of the range (40 to 80 pCi/kg wet weight) for cesium-137 in
marine fishes from all oceans (IAEA, 1976).  Specific analytical data
for cesium-137 in Atlantic ocean fishes, collected in deeper waters
(2100 meters), shows activity levels ranging to a maximum of 34 pCi/kg
wet weight (NEA, 1983).

(1)  Data presented here includes only those nuclides comparable to EERF

                                    31

-------
          When comparing  the  analytical  results  from  these  two Boston
 samples  to Atlantic ocean data only,  their  reported cesium-137 activites
 fall  into the upper portion of the  range given by NEA.   Using  the worst
 case  data reporting approach  in  this  instance would find the activity
 from  the two Boston samples exceeding the ranges for  cesium-137 reported
 by  the NEA.  It  is important  to  note here,  however, that the above
 comparisons of the Boston samples to the IAEA and NEA data  are made for
 analyses between different fish  species  samples  collected from disparate
 environmental regimes.  Furthermore,  the sample  preparations for
 radionuclide analyses are not analagous.  The IAEA and NEA  data sets
 pertain  to analyses of eviscerated  whole fish, muscle and viscera
 samples.  In this study the EERF analyses were performed on blended
 homogenates of the edible portions  of seafoods collected.   The levels of
 cesium-137 found in these two Boston samples from the EPA/FDA  study do,
 however, appear  to be reasonably consistent with the  baseline  data
 available.

          Table  12 also shows that  the EERF detected  plutonium-238 at
 a level  exceeding the MDL (1.5 pCi/kg wet weight) in  two of forty-one
 analyses.  One analysis was from a  Boston sample, the other from a San
 Francisco sample.  In Table 7A the  activity for  plutonium-238  in Winter
 flounder is reported as 1.7 (+_ 1.0) pCi/kg  wet weight, which definitely
 exceeds  the range for plutonium-238 that was found in other Boston Winter
 flounder samples, and also exceeds  the range for plutonium-238 observed
 in  other Massachusetts Bay flounder samples.  Plutonium-238 activity in
 the three other  samples of Winter flounder  collected  from Boston during
 this  study ranged from 0.06 to 0.3  pCi/kg wet weight  (mean  = 0.14),
 corresponding closely to  data from  the analyses  of eight flounder
 collected one year later, September 1982, in Massachusetts  Bay.   The
 plutonium-238 activity in those  samples  ranged from 0.04  to 0.5 pCi/kg
 wet weight, with a mean of 0.24  (CURTIS, 1984).  The  validity  of this 1.7
 pCi/kg analytical result  must, therefore, be Questioned.  It appears
 likely that the  reported  plutonium-238 activity  in this  sample may not
 represent true plutonium-238  activity.   This statement can  be  supported
 by  the large 2-sigma counting error value of + 1.0 pCi/kg for  this
 analysis, and the corresponding  analysis for plutonium-239  in  the  same
 sample (0.5 pCi/kg activity with a  large error term of 1.0  pCi/kg).   The
 questionable validity of  plutonium-238 activity  in this  sample can
 probably be attributed to laboratory error  during the sample preparation
 and analysis procedure and/or contaimination of  the sample  itself
 (LIVINGSTON, 1987).  In Table 1C the activity for plutonium-238 in
 Pacific hake is  reported  as 8.2  (+  10.8) pCi/kg  wet weight  which far
 exeeds baseline plutonium-238 activity levels in marine  fishes.   Again,
 due to the extremely large 2-sigma  counting error reported  with this
 analysis and the corresponding data for  analysis of plutonium-239  in the
 same sample (minus 1.2 pCi/kg activity and  a large error  term  of 2.3
 pCi/kg),  the validity of  this analytical result  is also  questionable.

          Repeat analyses by EERF on the homogenate samples yielded
 essentially the same results, indicating that the homogenates  were
contaminated.   As the original fish samples are  not available  for
 reprocessing,  additional  samples will be obtained for verification.
                                    32

-------
           From the data summarized in Table 12,  and from the above
 discussions about the four EERF analytical results for cesium-137 and
 plutonium-238 that were at or above MDL,  it is clear that 162 of the 164
 analyses show radioactivity in the thirty-seven  samples to be below or
 within expected environmental background  (ambient)  radiation levels,  due
 primarily from global fallout, as previously reported (DYER, 1976),  (IAEA,
 1976),  (NOSHKIN,  1978), (SCHELL,  1980),  (NEA,  1983 and 1985), and (CURTIS,
 1984) .

           Table 13 pertains only to data  contained in Tables 9,  10,  and
 11.   Analytical results from the 111 WEAC analyses for barium, cesium,
 iodine,  plutonium, and strontium are grouped into the same activity-level
 categories as given for the EERF data in  Table 12.   The WEAC reported
 measureable activity.- above detection limits,  for cesium-137 only.  The
 data listed in Tables 9,  10, and 11 shows the  twelve measurable  quantities
 for  cesium-137 from the thirty-seven analyses  performed by the WEAC.  Five
 of the twelve samples from Boston are listed with cesium-137 activity, as
 are  seven of the thirteen samples from San Francisco.   The WEAC  reports
 no measureable quantities of cesium-137 in any of the twelve samples
 collected from Atlantic City.  The WEAC further  reports that no  detectable
 activity for barium-140,  iodine-131, plutonium-239,  or strontium-90 was
 found in any of the thirty-seven samples  analyzed during this study.

           Measureable quantities of cesium-137,  reported by the  WEAC,
 range in the Boston samples from 12 to 45 pCi/kg (mean = 21)  and from 15
 to 30 pCi/kg (mean = 22)  in the San Francisco  samples.  These activity
 levels are reasonably consistent with the ranges of  cesium-137 previously
 reported for Pacific ocean fish (NOSHKIN, 1978)  and  (SCHELL,  1980).   The
 activity levels for these twelve  cesium-137 analyses are also within  the
 range of values observed  during the past  twelve  years of the FDA Total
 Diet Studies and Radionuclides in Foods monitoring programs.  The
 cesium-137 analytical results presented by WEAC  in this report are below
 levels  considered by the  FDA to be of public health  concern.  The data
 presented is also considered to be of normal background levels in seafood
 and  attributable  to global fallout over the oceans  (STROUBE,  1984).
4.2  Conclusions

          Direct numerical comparisons between  the EERF and WEAC analysis
data were difficult due to differences in each  laboratory's analytical
sensitivities and reporting procedures, and because of the number of WEAC
samples for which no numerical data was reported.  Analysis of the overall
Marketplace Seafood Monitoring Program data clearly shows, however, that
the levels of man-made radionuclides  in the samples were at or below those
levels normally found in foods (STROUBE, 1984).  All results were found to
be in the lower portion of Range I of the Federal Radiation Council
guidelines for radioactivity and similar to previous findings from FDA
analyses of imported fish obtained from retail  outlets (JELINEK, 1982).
Based upon the analytical data presented in this report, the EPA therefore
concludes that:
                                    33

-------
          (1) The analyses for man-made radionuclides in the seafood
samples collected show that radioactivity levels are at or below those
normally found in food samples.

          (2) Measureable levels of cesiom-137 and plutonium-238 activity
were detected in 16 of the 239 analyses (6.7%) completed by EERF and WEAC
during this monitoring program.  The activity levels observed in those 16
samples are, however, well below activity levels considered to be of
public health significance or concern.

          (3) The data show no evidence that previous LLW disposals
in Massachusetts Bay, at the Atlantic Ocean disposal sites, or at the
Farallon Islands disposal site have resulted in contamination of local
seafood populations with waste-related radionuclides.

          These conclusions are in accord with data previously reported
from FDA food study programs and in previous EPA reports of studies
conducted at the major U.S. ocean disposal sites for LLW.

                            ACKNOWLEDGMENTS
          Sincere gratitude  is expressed to Charles Jelinek, of the
Food and Drug Administration (FDA), for his assistance in planning
this monitoring program and  helping to get it started.  Gratitude is
also expressed to William Stroube  and William Cunningham, of the FDA,
for assisting in the evaluation of Winchester Engineering and
Analytical Center (WEAC) radioanalytical data, and for reviewing the
preliminary drafts of this report.  Recognition is also accorded to
Patrick Lombardo, Edmond Baretta and the staff at WEAC for preparing
the collected samples for analysis, shipping duplicate homogenates to
the EPA radiation laboratory, and  conducting radionuclide analyses.

     The cooperation provided to the author by Charles Porter and the
staff of the EPA Eastern Environmental Radiation Facility (EERF)
during this monitoring program was significant to its success. Two
members of the EERF staff, Jon Broadway and Geraldine Luster, were
particularly helpful in providing  and evaluating the data, answering
and responding to numerous questions and requests from the author, and
reviewing draft and final versions of the report.

     Special thanks also are extended to Victor Noshkin, of Lawrence
Livermore Laboratories, and  Hugh Livingston, of the Woods Hole
Oceanographic Institution, for their critical reviews of the report
and for their helpful suggestions  to me in presenting the data from
this monitoring program.  Critical reviews of the report by
Robert Dyer, William Gunter  and Michael Mardis, of the EPA Office of
Radiation Programs, are also gratefully appreciated.

     In addition, I wish to  thank  Raymond Clark  and Bonnie Wyvill, of
the EPA Office of Radiation  Programs, for their assistance.   Ray
provided the graphic art expertise displayed in Figure 1; Bonnie spent
countless hours typing and retyping text and tables.
