EXECUTIVE SUMMARY
This report presents the results of a radiological survey conducted in September 1997 by the U.S.
Environmental Protection Agency (EPA), National Air and Radiation Environmental Laboratory
(NAREL) to assess levels of environmental radioactivity in and around the Portsmouth Naval
Shipyard (PNS) in Kittery, Maine. The purpose of the survey was to assess whether the
construction, maintenance, overhaul, refueling, or operation of nuclear-powered warships have
created elevated levels of radioactivity that could expose nearby populations or contaminate the
environment.
During this survey, 135 samples were collected from 72 sampling locations. Samples included
drinking water, harbor water, sediment, sediment cores, and biota. All samples were analyzed
for gross alpha and beta activities and gamma emitting radionuclides. Water samples were also
analyzed for tritium, and some samples were analyzed for radium-226 and isotopes of uranium,
plutonium, and thorium.
No cobalt-60 was detected in samples obtained during this survey. Iodine-131 was detected in
one water sample and in most biota samples. The source of the iodine-131 is believed to be the
sewer discharges from nearby medical facilities since iodine-131 is frequently used in medical
procedures. All other radionuclides detected in the media collected during this survey are
radionuclides typically found in the environment including naturally occurring radionuclides
found in the uranium, thorium, and actinium decay chains; cosmogenic and primordial
radionuclides beryllium-7 and potassium-40; and cesium-137 resulting from atmospheric
weapons testing and the 1986 Chernobyl reactor accident.
In addition to sample collection and analysis, radiation surveys were performed at 48 sites using
portable survey instruments to determine gamma radiation levels. External measurements at
study locations were within natural background ranges.
Based on the results of this radiological survey, nuclear-powered warship operations at
Portsmouth Harbor have resulted in no increase in radioactivity causing significant population
exposure or contamination of the environment.

1.0 INTRODUCTION
The National Air and Radiation Environmental Laboratoiy (NAREL), in cooperation with the
U.S. Naval Sea Systems Command (NAVSEA) through a series of interagency agreements, has
conducted radiological surveys at facilities serving nuclear-powered warships. These surveys
began in 1963 and have been conducted on the Atlantic and Pacific coasts, the Gulf of Mexico,
and at Pearl Harbor, Hawaii. In 1996, NAVSEA and NAREL signed an interagency agreement
(IAG) to perform radiological surveys over the next five years at active U.S. facilities serving
nuclear-powered warships. These surveys assess whether the construction, maintenance,
operation, overhaul, or refueling of nuclear-powered warships has created elevated levels of
radioactivity that could result in potential exposure to nearby populations or contamination of
the environment.
The first environmental survey under this agreement was performed September 9 - 20,1996, at
the Puget Sound Naval Shipyard at Bremerton, Washington and the Naval Submarine Base near
Bangor, Washington (Fo98). The second environmental survey was performed March 17-27,
1997, at the Naval Station, San Diego; Naval Submarine Base, San Diego; and Naval Air
Station/North Island, San Diego (Go99).
This environmental survey, the third under the current IAG, was performed September 8-15,
1997, at the Portsmouth Naval Shipyard (PNS), Kittery, Maine. A pre-survey trip was made July
30-31, 1997, to initially develop a sampling and survey work plan with the assistance of
knowledgeable site personnel and the EPA Region 1 Radiation Program Manager who provided
information regarding issues of particular public interest. NAVSEA and PNS staff provided
NAREL personnel with information on past and present shipyard radiological operations and
procedures. Based on the information received and that derived from previous EPA studies, a
work plan (EPA97) was developed to describe the approach for assessing the radiological
condition of the PNS aquatic environment and immediate surroundings.
1.1 Site Description and History
Portsmouth Naval Shipyard is a public shipyard dedicated to the repair, overhaul, and
modernization of nuclear submarines. It is situated within the town limits of Kittery, in York
County, Maine and is located on an island in the Piscataqua River referred to as Seavey Island
(See Figure 1.0) with the eastern tip given the name Jamaica Island. Attached by a rock
causeway is Clark's Island which is not industrialized. PNS is joined to the mainland by two
bridges into Kittery.
The Piscataqua River is a tidal estuary which forms the boundary between New Hampshire and
Maine. PNS is located at the mouth of the Great Bay Estuary (commonly referred to as
Portsmouth Harbor), two miles from the Atlantic Ocean. The deepest part of the harbor is
approximately 75 feet in the channel at low tide. The bottom of the harbor is rock at many
1
-------
locations due to relatively swift currents resulting from tidal action and river flow. In other areas
the bottom is mud.
Portsmouth Harbor is naturally bounded by Kittery, ME on the north and Portsmouth, NH on the
south. The 1990 U.S. Census lists the population for Kittery, ME as 5,151 and for Portsmouth,
NH as 25,925. The water supply for Kittery, ME conies from Folly Pond, Middle Pond, Boulder
Pond, and Bell Marsh Reservoir, and for Portsmouth, NH from Bellamy Reservoir. PNS obtains
potable water from the Town of Kittery, ME.
Most of the harbor surrounding PNS is accessible to the public by boat with the exception of
certain areas close to Seavey Island which are restricted for security reasons. There are extensive
commercial fishing and recreational activities in the area, the most significant being lobstering.
There are many commercial and private lobster traps in the immediate vicinity of PNS.
Agriculture is not present along the perimeter of the harbor, which is occupied primarily by
commercial and residential lands.
PNS now consists of 278 acres, with 4.5 miles of shoreline, 10.5 miles of paved road, 7 miles
of railroad track, three drydocks, and 330 buildings. Its dimensions are approximately 6400 feet
(east-west) by 3800 feet (north-south). PNS has deepwater piers, drydocks, and numerous
moorings.
Beginning in 1958, Portsmouth Naval Shipyard was authorized to perform Naval Nuclear
Propulsion Program work. PNS was the first Government shipyard to build a nuclear-powered
submarine. The submarine USS SWORDFISH was commissioned in September 1958. In 1959
PNS completed USS SEA DRAGON, the first submarine to transit the Northwest Passage under
the polar ice cap. Also in 1959, Clark's Island was purchased. A causeway was established
between Seavey Island and Clark's Island, but Clark's Island was never industrialized.
PNS has been instrumental in some of the principal advances in submarine design. The USS
ALBACORE, reputedly the fastest and most maneuverable submarine of the time and forerunner
of today's high speed nuclear fleet, was designed and built at PNS. The hydrodynamic shape
pioneered by the ALBACORE has been used for all U.S. submarines since 1959.
Submarine construction at the shipyard terminated in 1971 with the delivery of the USS
SANDLANCE (SSN 660), a nuclear attack submarine of the SSN637 or STURGEON Class.
Between 1917 and 1971,134 submarines were produced at PNS. Since 1971, the workload at
PNS has consisted of a continuing overhaul and repair program for attack and fleet ballistic
missile submarines.
At present, Portsmouth Naval Shipyard is a large industrial complex capable of providing the fiill
range of industrial, manufacturing, and technological processes required for overhauling and
repairing the modern, high technology, nuclear-powered submarines of the U.S. Navy.

document [PNS98]).

1.2 Contaminants of Concern
The results of previous harbor surveys indicate that cobalt-60 is the predominant radionuclide
one expects to find in environmental media if radioactivity is present as a result of Naval nuclear
propulsion plant operations; therefore, environmental sampling during this study emphasized
detection of cobalt-60 (Ca77, Se88, Se89). Other radionuclides of concern in liquid effluents
or encountered during maintenance work include tungsten-187, chromium-51, hamium-181,
iron-59, iron-55, nickel-63, niobium-95, zirconium-95, tantalum-182, manganese-54, and
cobalt-58 (PNS98). Water samples were also analyzed for tritium, a contaminant of concern
since it is known to be produced in the coolant of nuclear reactors. In addition to these
radionuclides produced as a result of nuclear operations, attention was given to the determination
of the iodine-131 content of the samples. Iodine-131 is often used in medical diagnostic or
therapeutic procedures for the treatment of hyperthyroidism and thyroid cancer, both of which
are common disorders. Excreta from individuals undergoing medical diagnosis or therapy with
radioactive material are exempt from the U.S. Nuclear Regulatory Commission (NRC)
regulations for the discharge of radioactive materials into municipal sewer systems
(10CFR20.2003(b)). However, as NAREL has detected medical source iodine-131 in other
surveys, analyses were done for iodine-131 in the Portsmouth survey in an attempt to provide
a more complete characterization of the harbor.
1.3 Survey History
Cobalt-60 (half-life of 5.3 y) is the predominant radionuclide one would find in environmental
media if radioactivity were present as a result of Naval nuclear propulsion plant operations. The
Portsmouth Naval Shipyard was previously surveyed by USEPA-NAREL (then the Eastern
Environmental Radiation Facility) in 1977 (Ca79) and 1989 (Se91). During these surveys, no
cobalt-60 or other radionuclides attributable to shipyard operations were detected in any of the
environmental samples collected. In some samples, very low levels of radionuclides occurring
naturally in the environment or attributable to previous atmospheric nuclear weapons testing
were detected.
Cobalt-60 was detected in samples taken by the PNS and the State of Maine as follows (PNS98):
1965 Cobalt-60 detected in seaweed by State of Maine; highest concentration
was approximately 9 pCi/g.
1966 Cobalt-60 detected in harbor sediment by PNS; highest concentration was
approximately 11 pCi/cnr.
1966,67,69 Cobalt-60 detected in seaweed by PNS; highest concentration
approximately 4 pCi/g.
-------
At the time of the EPA 1977 survey, essentially two half-lives for cobalt-60 had passed since the
positive cobalt-60 sampling results listed previously. The Navy reports that until the early
1960's, some cobalt-60 was released to harbor water during maintenance operations on nuclear-
powered warships. Standardized instructions concerning discharges of radioactive liquids from
nuclear-powered warships were first issued in 1958. All instructions were consolidated in 1965
into a technical manual for use by all shipyards in their radiological control programs. During
1970, shipyards were directed to acquire the capability to collect, process, and reuse these
liquids. The Navy states that the basic policies instituted by about 1972 remain in place through
the present. (PNS98). The unit pCi/cm2 was used by the Navy from 1966 to 1970 and there was
no direct conversion to pCi/g available. The combination of reduction of cobalt-60 releases to
the harbor in the early 1960's and radioactive decay of early releases, in conjunction with
dispersion and possible removal by dredging, may explain why cobalt-60 was not detected in
EPA samples in the 1977 and 1989 surveys.
1.4 Study Objectives
The study objectives were to determine if radioactive material related to U.S. Naval nuclear-
powered warship operations, repair, and maintenance is present at measurable levels in the
Portsmouth Harbor, to make comparisons of current study results with past study results and, as
deemed necessary, to estimate potential doses to the public.
-------
2.0 SAMPLING, MEASUREMENT, and ANALYSIS
The following terms will be used in the discussion of the sampling and measurements:
Study Site: The geographical area in and around Portsmouth Harbor
that was studied.
Measurement Location: A location in or near the study site where gamma-ray
exposure rates were measured.
Sampling Location: A location within or near the study site from which
samples were collected.
Background Location: A selected sampling location where representative levels
of naturally occurring or existing radionuclides were
measured, but were not likely to be related to Portsmouth
Naval Shipyard operations.
2.1 Sampling, Measurement, and Analysis Strategy
This survey was intended to determine the concentrations of cobalt-60 and other selected
radionuclides that could be present due to the operations performed at Portsmouth Naval
Shipyard. Sampling locations were preselected to correspond to the locations where the Navy
conducts environmental monitoring, locations where the USEPA-EERF (later renamed the
NAREL) sampled in the 1977 and 1989 surveys, and locations which were selected by the
USEPA-NAREL to more comprehensively characterize the site during this survey.
Background sampling locations were selected in order to obtain baseline radionuclide levels that
are characteristic of the area, but are believed not to have been affected by operations at the study
site. The data from the study site were compared directly to the background concentrations when
applicable or to appropriate standards, such as the drinking water regulation. Two sites were
selected as background locations.
Field duplicate samples were either co-located (adjacent) or split samples. Biota, bottom
sediment, and water samples were typically composited at the site upon collection and split into
duplicate samples. Duplicate core samples and shoreline sediment were collected as adjacent
samples at the same site location. Duplicates were taken at eleven sampling locations resulting
in 38 samples (19 duplicate pairs).
In some cases, preselected sample or measurement locations could not be used due to the
presence of moored ships, construction, type of water craft available, location logistics, or
unsuitable environmental conditions. Other locations were added during the survey to maintain
-------
site coverage. Such changes from the workplan (EPA97) are noted in the discussion in Section
3.0. Similarly, not all biota noted in the workplan were obtained; however, the most prevalent
species at each site was collected which, at some sites, included species not originally identified
in the workplan.
2.1.1 Sample Identification
Each sample or measurement collected during the survey was marked with a unique code which
denoted:
• Collection location
• Matrix or Measurement type, which for biota included species identifiers
• Descriptive Suffix, for field duplicates, background sites, and sewer outfall locations
The sample code has the form PNSxxx-yyyy[-zz] where 'xxx' is the location identification
number and 'yyyy' is a text code identifying the measurement type or matrix (and species for
biota samples.) Suffixes, -zz, were used for additional descriptive information: '-DU' if the
sample was a duplicate sample; '-BG' if the sample was acquired at a background location; or
'-SO' if the sample was acquired at a sewer outfall depth. Not all samples required the use of
all characters. Codes used in this survey are shown in Table 1.
All sample and measurement locations are listed in Table 2 with the type of sample or
measurement acquired at that location identified. Duplicate and background locations are also
noted in this table. Refer to Appendix B, Table B.I for the detailed listing of type and number
of all samples except water samples collected from each site.
2.1.2 Background Sampling Locations
The background locations selected were location PNS001, which is 300 yards south of Adams
Point, and location PNS048, Seward Cove, approximately 200 yards off the pier at Fort Foster
Park (see Table 2 and Figures 2.0,3.1-5.0). The background locations were selected during the
pre-survey and are located at distances far enough away from the study sites so that PNS
radiological operations would likely not have impacted these locations. However, background
samples typically do contain levels of radionuclides that result from worldwide fallout and
natural radioactivity (EPA73).
2.1.3 Portsmouth Naval Shipyard and Environs Sampling and Measurement Locations
The study site is located near Seavey Island within and on the shores of the Piscataqua River and
Portsmouth Harbor. Sampling locations presently used by the Navy, the 1989 EPA sampling
8
-------
locations, and sampling locations added by EPA-NAREL were used during this study. The type
of sample collected and the approximate location of each sampling site are shown in Figures
2.0-5.0. Descriptions of each sampling location and the types of samples collected at each
location are presented in Table 2. Duplicates of one or more media and, for biota, duplicates of
multiple species may have been taken at a site. During the study, 135 samples were collected
from 72 sampling locations. In addition to sample collection and analysis, radiation surveys
were performed using portable survey instruments to measure gamma-ray levels in the
environment at 48 sites. External measurement locations are shown on Figure 6.0.

• Each location is identified by a unique location identifier. Latitude and longitude were determined by Geographic Postioning System (GPS) units, with a typical accuracy of about 100 meters
and were verified using NOAA nautical charts and map interpolation for an approximate accuracy of 30 meters.
*Type of biota collected depended on availability. More than one species of biota were collected at several locations.
' Duplicate samples were taken at the locations marked by DU. In some cases a duplicate of only one media was taken at the location. For specific information on type of duplicates taken at
each location, refer to the Field ID descriptor in the appendixes.
* Where distance is not specified, samples were taken as close to the piers as the situation permitted. When barges, ships, or other impediments prevented sampling at a specified location, the
sample was collected as close as possible to the specified location and the alternate location was noted.
-------
2.2 Sample Collection, Preparation, and Analysis
Shoreline (intertidal) sediment, harbor bottom sediment (grab and core), water (harbor surface,
sewage outfall, and drinking waters), and biota were collected. By previous agreement between
USEPA-NAREL and the Navy, most samples were split for routine independent comparisons
by the Navy. For each sample type, a minimum of 10% quality control duplicates were collected.
The locations where duplicate samples were taken are noted in the referenced tables.
2.2.1 Sample Collection and Preparation
Harbor Bottom Sediment. Each sample consists of approximately four liters of harbor-bottom
sediment collected from the top 10 cm of the harbor floor with a Petersen dredge. In several
locations the sediment samples were collected by the divers rather than with the Petersen dredge
(PNS001, 004, 005, 006, 016, 020, 023, 028, 029, 035, 040, 042, 048, 049, 056) Sediment
samples were oven dried prior to analysis. A total of 64 sediment samples were collected, of
which 7 were duplicate samples collected for quality assurance purposes. Two sediment samples
were collected from background locations.
Shoreline Sediment. Each sample consists of approximately four liters of surface soil collected
by trowel from the intertidal shoreline near the low tide line. Stones and organic debris were
excluded as much as possible. Any remaining debris was removed by sieving with a 16-mesh
sieve during sample preparation at the laboratory. Shoreline samples were oven dried before
analysis. A total of 10 shoreline samples were collected, of which 1 was a duplicate sample
collected for quality assurance purposes.
Sediment core. Each sediment core consists of a 5 cm diameter cylinder of harbor sediment up
to 40 cm in length. Core samples were collected by Navy divers who pushed a plastic tube
vertically into the harbor bottom as far as possible, then capped the ends. Excess water was
decanted from the top of each core. The cores were frozen prior to shipping and remained frozen
during shipping. Before analysis, the frozen cores were cut into sections. Each core section was
oven dried. A total of 7 core samples were collected, of which 1 was a duplicate sample
collected for quality assurance purposes. The 7 cores were divided into a total of 32 sections for
analysis. Section identifiers and corresponding section depth for each core sample is found in
Appendix B. Two cores were collected from the background locations.
Harbor Water. Each sample consists of approximately 4.5 liters of harbor water collected with
a horizontal Wildco alpha bottle at a depth of one meter. In addition a harbor sample was taken
at the location and depth of the sewer outfall. Samples were divided into two portions. About
four liters of water was poured into a plastic container and acidified with nitric acid to a pH of
less than 2. The remaining 0.5 liters was poured into a glass container but was not acidified.
The four liter portion was analyzed for gross alpha, gross beta, and gamma-ray emitting
radionuclide activity with a percentage of the samples also analyzed for specific radionuclides.
16
-------
The 0.5 liter portion was analyzed for tritium activity. A total of 18 harbor water samples were
collected, of which 2 were duplicate samples. Two of these samples were taken at the sewer
outfall depth and two were taken from background locations.
Drinking Water. Each sample consists of approximately 4.5 liters of tap water. The drinking
water samples were divided, prepared, and analyzed in the same manner as the harbor water
samples. A total of 4 drinking water samples were collected, of which 1 was a duplicate sample
collected for quality assurance purposes.
Biota. Each sample consists of approximately four liters of one species of marine life. Biota
samples were collected by Navy divers from as small a region of the harbor bottom as possible.
The divers were instructed to collect the predominant species at the location, both plant and
animal, without collecting species protected by law. Biota samples were homogenized in the
field, frozen for shipping, and thawed for radioanalysis. A total of 32 biota samples were
collected, of which 7 were duplicate samples collected for quality assurance purposes. Five biota
samples were collected from the background sites.
PNS023 and PNS024, as proposed in the workplan, were combined as one location because of
the close proximity of the locations. The location is identified as PNS023. Other sample
locations that were repositioned include: location PNS001 which was moved 100 yards north,
location PNS003 located between Dover Point and Dover Point boat launch, PNS055 positioned
on the shipyard side near bldg 357 and H27, and PNS060 at the pier rather than south of the pier.
Sampling locations 101-113,126-128 were added during the survey.
2.2.2 Sample Analysis
Samples from each location were analyzed for gamma emitting radionuclides and for gross
alpha/beta activities. Of particular interest was cobalt-60 in the sediment samples and iodine-131
in the water and biota samples. All water samples were analyzed for tritium. Specific isotopic
analyses were performed on selected samples.
Gamma Spectrometry. This procedure allows for characterization of the gamma-emitting
radionuclides present in the sample without separating them from the sample matrix. The limit
of detectability of this method is a function of the sample size, counting geometry, detector
efficiency, background, counting time, gamma photon energy of the nuclide, and branching ratio
(percent abundance). Liquid samples are acidified and soil or sediment samples are ground and
sieved to ensure the homogeneity of the samples. Biota samples are homogenized prior to
analysis to ensure uniformity of the sample.
Gross Alpha/Beta. This procedure provides a rapid screening measurement was used as a gross
approximation of the alpha and beta activity present in the sample. Low energy and volatile
radionuclides such as tritium, carbon-14, and iodine will not be detected by this method. In
17
-------
addition, polonium and cesium may be lost if the procedure requires flaming of the sample. For
water samples, a known amount of the sample is evaporated to a small volume then transferred
to a small container and further evaporated for measurement. For solid samples, a known
amount of the sample is placed on the planchet. Water is added and the sample is dried to
provide even distribution. The sample is weighed and counted on a gas proportional counter.
These analyses are not as accurate as their isotopic counterparts.
Tritium Analysis. Water samples are distilled and are incorporated into a counting mixture
consisting of a primary solvent, emulsifier, and fluors. The tritium is assayed in a liquid
scintillation spectrometer.
Specific isotopic analyses included radium-226, uranium, thorium, and plutonium by
radiochemical separation.
Radium-226. The radium-226 radiochemical separation method is used to prepare samples for
determination by de-emanation. De-emanation is the process by which a gaseous product of the
radioactive decay, radon-222, is transferred into a counting cell by sparging with an inert gas.
Solid samples are first solubilized. Solid samples containing large amounts of organic material
are dried and ashed before analysis by this procedure. Radium-226 is separated from other
species in the solution, by coprecipitation with barium. After converting the barium(radium) to
the soluble chloride, the precipitate is dissolved in water and sealed in a glass tube. The sealed
sample is stored to allow the ingrowth of the radon-222. Following an ingrowth period, the
accumulated radon-222 is quantitatively transferred to evacuated Lucas alpha scintillation
counting cells where it is measured by scintillation counting.
Uranium and Thorium Isotopes. This procedure is applicable for the measurement of thorium-
232, thorium-230, thorium-228, and thorium-227 and for uranium-238, uranium-235, and
uranium-234. Solid samples containing large amounts of organic material are dried and ashed
before analysis by this procedure. Waters containing visible solid material are filtered before
analysis and the solid material analyzed separately if desired. Thorium-234 and uranium-232
tracers are added to the samples to determine chemical recovery. Solid samples are solubilized
by treatment with hydrofluoric, nitric, perchloric, and hydrochloric acids. Water samples are
evaporated prior to extraction. The uranium is extracted into triisooctylamine (TIOA) from a
hydrochloric acid solution, eluted with dilute hydrochloric acid and nitric acid, purified and
coprecipitated. The thorium is purified by adsorption on an anion exchange resin, eluted, and
coprecipitated. Each actinide is radioassayed by alpha spectroscopy.
Plutonium Analysis. Solid samples containing large amounts of organic material are dried and
ashed before analysis by this procedure. Waters containing visible solid material are filtered
before analysis and the solid material analyzed separately if desired. Plutonium-242 tracer is
added to a weighed or measured sample aliquot. Solid samples are solubilized. Plutonium is
extracted from a hydrochloric acid solution of the sample into triisooctylamine (TIOA) solution
in para-xylene. After washing the TIOA with dilute hydrochloric acid, the plutonium is stripped
18
-------
from the TIOA with dilute nitric acid and dilute hydrochloric acid. The strip solution is wet
ashed and the plutonium is coprecipitated with lanthanum as a fluoride. The precipitate is
filtered and radioassayed by alpha spectroscopy. This analytical procedure does not distinguish
between plutonium-239 and plutonium-240. Therefore, the total activity of these two isotopes
is reported.
2.3 External Measurements
At selected locations, radiation surveys were performed using portable survey instruments to
detect gamma radiation. External radiation measurement locations are presented in Table 2 and
measurements are shown in Figure 6.0. Measurements were taken at 48 sites with duplicate
measurements made at 4 sites for quality assurance purposes. External gamma radiation was
measured with a Ludlum Model 19 Nal(Tl) radiation survey instrument, a GENITRON
GammaTracer instrument, which consists of two energy-compensated Geiger Mueller tubes, and
a Reuter-Stokes RSS-112 pressurized ionization chamber. Underwater measurements of gamma
radiation were performed using a 6"x6" Nal(Tl) detector and an EG&G ORTEC "Nomad +"
multichannel analyzer at selected sites where sediment core samples were collected. The
resulting spectra were visually examined while at the site to determine whether additional
sampling was necessary.
2.4 Locational Data
The maps for the Portsmouth survey were derived from two standard nautical charts purchased
from NOAA, The Charts were number 13285 "Portsmouth to Dover and Exeter" Nov. 3,1990,
and number 13283 "Cape Neddick Harbor to Isles of Shoals" Dec. 23, 1995. The projection is
Mercator and Datum is WGS 84. Commercially scanned images of the charts were used in ESRI
ARC/INFO to trace shoreline coverages and exported as Arc View shapefiles.
For each sample and measurement location, the approximate geographical position (latitude and
longitude) of the location was determined in the field using either a Trimble Ensign or a Trimble
Scout global-positioning system (GPS) receiver. The resulting geographical positions are
generally assumed to be accurate to within approximately 100 meters. The resulting
geographical data and written description of the sampling location, as recorded by the sampler,
were compared with the nautical maps.
Most positions recorded in Table 2 reflect map interpolation. The accuracy of manually plotted
points on the maps is estimated to be 30 meters. There were no field GPS readings for locations
PNS080 and PNS081. The locational information for these sites was obtained by referencing
the description recorded by the sampler, marking this position on the ArcView maps, and
generating the approximate geographical position.

3.0 RESULTS AND DISCUSSION
The radioanalytical results for the samples collected during this survey are presented in Appendix
A, Tables A.I - A.27. The tables were generated from the NAREL database of radioanalysis
results. The radioanalytical results and quality assurance/quality control (QA/QC) information
for the laboratory analyses were reported in the NAREL Data Packages (EPA98) for this project.
The QA/QC results were within acceptable limits.
Some of the reported radionuclide results are negative. Negative results occur when a previously
determined detector background count rate is subtracted from a sample count rate that is less than
that of the background count rate. Negative values represent a portion of the distribution of
negative and positive values around zero for a sample containing very little or no radioactivity.
The activity and 2-sigma uncertainty for radionuclides measured by gamma spectrometry are
reported in the tables only if the nuclide is detected. In some cases, the results of gamma
spectrometry analyses are reported as "not detected" (ND). This means that in all likelihood, the
radionuclide in question is either not present in the sample or is present at a concentration below
the minimum detectable concentration (MDC). The MDC is the concentration of analyte that
must be present in a laboratory sample to give a specified high probability (usually 95%) of
detection. NOTE: The detection criterion must be specified before the MDC can be calculated.
The criterion is usually chosen to ensure no more than a 5% probability of false detection in a
blank sample. With the exception of cobalt-60, nuclides that were not detected in any of the
samples are not listed in this report.
3.1 Water Samples
3.1.1 Harbor Waters
Sixteen surface water samples, which included 2 duplicates and 2 backgrounds, and 2 harbor
water samples at the sewer outfall depth were collected. Modifications to the workplan for the
harbor water sample collection and analysis are as follows. The sewer outfall at PNS006 was
not located by the divers; therefore, no sample at the depth of the outfall was obtained at this site.
Harbor water collection was added at PNS043. During transit to the laboratory, the sample
container for tritium analysis for site PNS014 was broken; therefore, no tritium results were
obtained for this sample. In addition, no sample was received for tritium analysis for location
PNS033.
The gamma analysis results are shown in Tables A. 1 and A.2. Nuclides of particular interest for
this study were cobalt-60 and iodine-131. Cobalt-60 was not detected in these samples. The
highest MDC calculated during the spectrometric analysis for cobalt-60 was 3.27 pCi/L. The
sample from location PNS004, the Newington water treatment plant outfall, at the depth of the
sewer outfall produced an iodine-131 result of 8.41 ± 2.13 pCi/L. No other water samples
27
-------
indicated positive iodine-131 results. The source of the iodine-131 is believed to be the sewer
discharges from nearby medical facilities.
Other radionuclides detected by gamma spectrometry include naturally occurring lead-214,
bismuth-214, lead-212, potassium-40, and thallium-208. Tritium analyses were performed on
all harbor water samples (except as previously noted), and the results for these analyses are
presented in Table A. 16. All of the concentrations were below the MDC of approximately 160
pCi/L.
Results of the gross alpha and beta analyses of harbor water samples are presented in Table A. 11.
The gross alpha analyses for the background samples (PNS001 and PNS048) produced negative
results with the gross beta analysis for the background samples resulting in 200 to 300 pCi/L.
Harbor water samples had alpha concentrations ranging from -44.86 ± 55.57 pCi/L to 71.22 ±
97.34 pCi/L and gross beta results ranging from 28.73 ± 9.33 to 310.60 ± 95.72 pCi/L. The
potassium-40 gamma analysis results for these waters ranged from 27.80 ± 17.70 pCi/L to
335.00 ± 27.00pCi/L indicating that potassium-40 is the primary contributor to the gross beta
concentrations. On evaluation, the gross alpha and beta activities of samples taken from the
study sites were comparable to the activities of samples taken from the background sites.
Chemical separations for isotopic analyses were performed on 10 samples for radium-226 and
on 2 samples for uranium, thorium, and plutonium. Results of these isotopic analyses of harbor
water samples are presented in Tables A. 19 and A.23 respectively. Isotopic analyses included
both background and study samples.
3.1.2 Drinking Waters
The gamma analysis results for the four drinking water samples, which includes one field
duplicate, are shown in Tables A.3 and A.4. Only naturally occurring radionuclides, lead-212,
lead-214, and bismuth-214, were detected in the drinking water samples collected during this
survey. Tritium analyses were performed on all drinking water samples and the results are
presented in Table A. 17. The concentrations were below the MDC of about 160 pCi/L.
Results of the gross alpha and beta analyses of drinking water samples are presented in Table
A. 12. The drinking water samples had maximum gross alpha and beta concentrations,
respectively, of 0.26 ± 0.46 pCi/L and 2.6 ± 1.0 pCi/L. Similar activity levels were detected
in the study samples and the background samples.
All drinking water samples in this study were analyzed for radium-226. The radium-226 results
ranged from 0.06 ± 0.01 to 0.13 ± 0.01 pCi/L and are included in Table A.18. No actinide
analyses were performed on these waters.
The National Interim Drinking Water Regulations (EPA76), 40 CFR 141.15, state that the
maximum allowed gross alpha particle radioactivity in community water systems as 15 pCi/L,
28
-------
including radium-226 but excluding radon and uranium. Gross alpha concentrations in drinking
waters collected for this study were below the maximum allowed gross alpha activity in drinking
water for community water systems.
3.2 Sediment and Sediment Core Samples
3.2.1 Harbor Bottom and Shoreline (Intertidal) Sediment
A total of seventy-four sediment samples were collected. Of these samples, 64 were harbor
bottom sediment samples, including 7 duplicates, and 2 background harbor bottom sediment
samples. Ten samples were shoreline sediment samples, including 1 duplicate.
Changes made during the survey from the workplan included: harbor bottom sediment samples
were not obtained at locations PNS013, 034, 041, 043, or 047, no duplicate sediment was
received at the laboratory for PNS006, sites PNS 126-128 were added as harbor bottom sediment
locations, and PNS030 and PNS 126 were added as duplicate locations for sampling harbor
bottom sediment. For the shoreline sediment locations, a sample was taken at location PNS 113
Wallis Sands State Park Beach since the harbor bottom sediment at location PNS047 offshore
from Wallis Sands State Park could not be obtained. The sample from PNS113 is the only
sediment sample for this vicinity. In addition, shoreline sediment collection was added at
external measurement locations PNS068,075,078,098, and 110 through 112.
All sediment samples were dried, sieved, homogenized, and analyzed for gamma-ray emitting
radionuclides and gross alpha and beta activity. Radiochemical separations for isotopic analyses
were performed on selected ashed samples, generally those with higher gross alpha/beta results
or from background locations. Results for the analysis of sediment are presented in units of
pCi/g-dry. (See Appendix B for mass conversion ratios.)
The gamma analysis results are shown in Tables A.5 and A.6 of Appendix A. No cobalt-60 was
detected in any of the harbor or shoreline sediment samples collected during the Portsmouth
survey. The highest cobalt-60 MDC calculated during analysis of sediment samples was 0.064
pCi/g-dry. Other gamma-ray emitting radionuclides detected included naturally occurring
radioactivity found in the uranium, thorium, and actinium decay chains; cosmogenic and
primordial radionuclides beryllium-7 and potassium-40, and cesium-137, typically found in the
environment as a result of atmospheric weapons testing or the Chernobyl reactor accident. These
radionuclides were detected in nearly all of the sediment samples at levels consistent with those
found in other surveys. The results were comparable between the study locations and the
background locations.
No tritium analyses were performed on harbor and shoreline sediment samples.
Results of the gross alpha and beta analyses of harbor and shoreline sediment samples are
29
-------
presented in Table A. 13. The maximum result for gross alpha and gross beta activities at the
background locations, respectively, were 18.12 ± 7.38 and 25.21 ± 4.04 pCi/g-dry. The study
sample results ranged from -1.07 ± 2.78 to 35.31 ± 10.05 pCi/g-dry gross alpha activity and
13.15 ± 3.25 to 37.62 ± 4.58 pCi/g-dry gross beta activity. On comparison, the activities at study
sites and background sites are similar.
Radiochemical separation and isotopic analysis for radium-226 was performed on nine harbor
bottom sediment samples including two samples from background locations. These results are
consistent with naturally occurring levels of radium and are presented in Table A.20.
Uranium, thorium, and plutonium analyses were performed on one background and one study
location sample. Results of these analyses are presented in Tables A.24 and A.25, respectively.
3.2.2 Harbor Core Samples
Seven sediment core samples were taken including 1 duplicate sample and 2 samples from
background sites. A core sample was not obtained from location PNS043. Core sample
collection was added at location PNS049.
All sediment and core sample segments were dried, sieved, homogenized, and analyzed for
gamma-ray emitting radionuclides and gross alpha/beta. Isotopic analyses were performed on
selected ashed samples. Results for the analysis of core samples are presented in units of pCi/g-
dry. (See Appendix B for mass conversion.)
Results for the gamma analysis are included in Tables A.7 and A.8. There was no cobalt-60
detected in any of the core sections. The highest MDC was 0.777 pCi/g-dry. The distribution
of other gamma-ray emitting radionuclides in the cores samples at each depth was relatively
consistent and included naturally occurring radioactivity found in the uranium, thorium, and
actinium decay chains; cosmogenic and primordial radionuclides beryllium-7 and potassium-40,
and cesium-137, typically found in the environment as a result of atmospheric weapons testing
and the Chernobyl reactor accident. Results were consistent between background and study
locations.
No tritium analyses were performed on the core samples.
Results of the gross alpha and beta analyses are presented in Table A. 14. The gross alpha results
for the background core sections (PNS001,5 sections, and PNS048,5 sections) ranged from 3.79
± 4.14 to 29.25 ± 10.5 pCi/g-dry and the gross beta analysis for the background samples ranging
from 22.90 ± 3.88 to 33.06 ± 4.32 pCi/g-dry. Study location core sections had alpha
concentrations ranged from 2.45 ± 3.69 to 37.02 ± 10.86 pCi/g-dry and gross beta results ranging
from 15.23 ± 3.32 to 32.89 ± 4.43 pCi/g-dry. The results for the background and study locations
were comparable.
30
-------
Radium-226 analysis was performed on 12 core sections from 4 core samples. Radiochemical
separation for radium-226 was performed on all sections of the cores from the two background
locations and on two sections of study location cores. The results are shown in Table A.2L
No actinide analyses were performed on the core sections.
Underwater gamma scintillation probe measurements were also made at each core sampling site.
The probe is less sensitive than the laboratory detectors and is used as a gross screening
technique. If radioactivity above background is detected with the underwater probe, additional
sediment samples are taken in the area to quantify the radionuclide concentrations. An
anomalous reading was detected at PNS040. A second measurement was made at the site and
the calibration of the detector was immediately checked. It was determined that the energy
calibration had shifted due to temperature changes and the peak was potassium-40, a naturally
occurring radionuclide. The detector was recalibrated. The results for the core and sediment
samples that were taken at this location were consistent with results from other locations and are
included in Tables A.7, A.8, and A. 14.
3.3 Biota Samples
Thirty-two biota samples were collected, including 7 duplicates and 5 background samples. No
biota were obtained from location PNS044 due to the limited clearance under the bridge nor
were biota obtained at location PNS006. Location PNS127 was added as a biota collection
location.
All biota samples were homogenized and analyzed "wet" for gamma-ray emitting radionuclides.
The results of the gamma analyses for these samples are shown in Tables A.9 and A. 10. Gross
alpha and beta and isotopic analyses were performed on ashed samples. Gross alpha and beta
results are shown in Table A. 15 and isotopic results in Tables A.22, A.26, and A.27. Results of
the analysis of biota samples are presented in pCi/g-wet. (See Appendix B for mass conversion
ratios.)
Nuclides of primary interest for this survey were cobalt-60 and iodine-131. No cobalt-60 was
detected in any biota samples. The highest MDC for cobalt-60 was 0.026 pCi/g-wet. Iodine-131
was not detected in the crab or sand dollar samples but was detected in all other biota species
collected. The maximum iodine-131 concentration in the biota was 0.22 ±0.01 pCi/g-wet. The
maximum concentration was found in the brown sea hair samples. Iodine-131, with a half-life
of 8.04 days, is often used in medical diagnostic or therapeutic procedures. Excreta from
individuals undergoing medical diagnosis or therapy with radioactive material is exempt from
the U.S. Nuclear Regulatory Commission (NRC) regulations for the discharge of radioactive
materials into municipal sewer systems. A trace amount of cesium-137 was detected in two
biota samples, both brown sea hair samples.
31
-------
The range of results for gross alpha and beta, respectively, are 0.08 ± 0.39 to 4.8 ± 3.4 pCi/g-wet
and 1.47 ± 0.12 to 13.31 ± 0.76 pCi/g-wet. Comparisons were made among those species found
at both background and study sites. These comparisons included brown kelp (including brown
split kelp), brown sea hair, and lobster samples. Gross alpha and beta activities were similar
between the background and the study sites for these species.
Radiochemical separation for actinides was performed on 7 samples and radium-226 analysis
was performed on 11 samples. Three of these samples were collected at the background
locations. Sample results are listed in Tables A.22, A.26 and A.27, and mass conversion ratios
are in Table B.I.
3.4 External Radiation Measurements
External radiation measurements were made along the shoreline and in the harbor with emphasis
on areas accessible to the public. Measurements were recorded during the survey with a
GENITRON Instruments GammaTRACER GM-based survey instrument and readings were
downloaded at the shoreline external monitoring locations. External exposure readings were
taken for 5 to 10 minutes at most shoreline locations with a Reuter Stokes model RSS-112
pressurized ion chamber (PIC). A Ludlum Model 19 was also used to measure variations in
exposure rates along the shoreline at each location. Measurements were made only with the
Ludlum survey meter at locations over the water. External monitoring location survey results
are shown in Table C.I.
The Ludl^easurements at locations PNS074 and PNS098 were approximately 20 uR/h and
at location PNS097 the measurements were approximately 15 uR/h in contrast to other locations
with measurements less than 10 uR/h. At location PNS074, the Ludlum Model 19 measurement
was made against a granite sea wall and was higher than the Genitron and PIC measurements
which were taken a short distance away from the wall. At location PNS097 the Ludlum
measurement was taken on a granite wall. The PIC reading was taken approximately 3 feet in
front of the wall and the Gemtron reading was taken by the parking lot. Location PNS 098 was
at the entrance gate to Fort Constitution.

4.0 QUALITY ASSURANCE/QUALITY CONTROL (QA/QC)
The Quality Management Plan (QMP)(EPA96) applies to all work performed at NAREL. The
purpose of the quality assurance program is to ensure that all measurements performed at
NAREL are valid, scientifically defensible, and of known precision and accuracy. Quality
assurance is equally important in the sample collection process. Sampling equipment was in
good working order and field measurement equipment was calibrated and properly maintained.
In the field, for each sample type and batch of up to 20 samples, a field duplicate was collected.
The field duplicate results assess the consistency of the sampling process and the
representativeness of the samples collected. Field duplicates were collected for 19 samples.
Duplicate measurements were taken at 4 of 48 external measurement locations for quality
assurance purposes.
In the laboratory, samples were grouped in batches for quality control purposes, with a maximum
of 20 samples per matrix per analysis type. For each batch, the laboratory analyzed a reagent
blank, a matrix spike, a matrix spike duplicate, and a laboratory replicate sample. However, for
gamma spectrometry and gross alpha and beta analyses, only a recount (duplicate) or split was
performed for batch QC. Results of these QC samples were reviewed with sample results as part
of the data verification process. All blank results were maintained on control charts by analyst,
matrix, and analyte. Warning and rejection limits were used to assess acceptance of the blank
results. Detailed results are included in the NAREL Data Packages (EPA98) and all
radioanalytical sample results in accordance with the QAPP as certified by the NAREL Quality
Assurance Coordinator and the Chief of the Monitoring and Analytical Services Branch.
It is NAREL policy to participate in many intralaboratory comparisons of radioactivity
measurements and interlaboratory cross-check programs. NAREL participates in
intercomparison QA studies with the EPA Office of Research and Development Environmental
Science Division (ORD-ESD) in Las Vegas; the National Institute of Standards and Technology
(NIST) in Gaithersburg, MD; the World Health Organization (WHO) in Le Vesinet, France; the
International Atomic Energy Agency (IAEA), Vienna, Austria; and Analytics, a commercial
company in Atlanta, Georgia. The most comprehensive of these QA studies at the time of this
survey was with EPA's ORD-ESD Laboratory in Las Vegas, which supplied NAREL with thirty
cross-check samples a year in water, milk, and food. The ORD program was discontinued in
December 1998. NAREL now also participates in QA comparisons with the DOE Radiological
and Environmental Science Laboratory in Idaho Falls, ID and the Department of Energy (DOE)
Environmental Measurements Laboratory (EML) in New York, NY. Soil, vegetation, water, and
air filters are received through these intercomparison programs.

5.0 CONCLUSIONS
The radiological survey at the Portsmouth Harbor provides the basis for the following
conclusions:
No cobalt-60 was detected in samples obtained during this survey. Harbor water,
drinking water, representative biota, and sediment (shoreline, harbor bottom, and core)
samples were collected.
Iodine-131 was detected in one water sample and in most biota samples. Iodine-131 was
not detected in the crab and sand dollar samples but was detected in other biota samples
with the maximum concentration (0.22 ± 0.01 pCi/g-wet) in the brown sea hair sample
collected at location PNS042, Berth 6. The harbor sample taken at the Newington water
treatment outfall contained 8.4 ± 2.1 pCi/L of iodine-131. Iodine-131, with a half life
8.04 days, is often used in medical diagnostic or therapeutic procedures and may
concentrate in marine biota. It is believed that the iodine-131 found in these samples is
present as a result of medical procedures.
All other radionuclides detected in the media collected during this survey are
radionuclides typically found in the environment including naturally occurring
radionuclides found in the uranium, thorium, and actinium decay chains; cosmogenic and
primordial radionuclides beryllium-7 and potassium-40, and cesium-137 resulting from
atmospheric weapons testing and the Chernobyl reactor accident. The concentrations of
these radionuclides are typical of those found elsewhere in the environment.
External measurements at study locations were within natural background ranges.
Based on the results of the media sampled during this radiological survey, nuclear-
powered warship operations at Portsmouth Harbor have resulted in no increase in
radioactivity causing significant population exposure or contamination of the
environment.
