ABSTRACT This report presents the data obtained from the analyses of environmental samples collected through the Virginia Electric Power Company Surry Station Environmental Radiological Surveillance Program for the period 01 January 1981 through 31 December 198l.
The_ activity present above detection limits in the routinely collected sample media was observed to be of natural and atmospheric fallout origin.
The results show that the radiation dose to a member of the general population did not exceed the technical specifications of 17. of the 10 CFR 20 limit during 1981.

INTRODUCTION
- The Surry Power Station of Virginia Electric and Power Company consists of *two Westinghouse pressurized water reactors each with a generating capacity of 788 MWE. The station is located on a peninsula in the James River approxi-mately 25 miles upstream of the Chesapeake Bay. Cooling water is taken in down-stream of the site and discharged 5.7 miles upstream of the intake. The Surry Power Station has been designed to minimize radioactive releases and insure that radiation doses attributed to the operation of the station will be "as low as reasonably achievable".
- Various environmental samples are collected at indicator and control or bacl!}ground locations and analyzed to determine if changes in radioactivity levels may be attributable to the operation of the station. This environmental radio-logical monitoring program provides surveillance to assure compliance with the NRC Regulations and the Surry Power Station Technical Specifications.
The program outlined in Tables 1 and 2 has in some cases more frequent collection and analysis of certain samples than called for in the Technical Specif lea tlons. The accompanying map shows the plant environs. '£able 4 surnrnar-izes the results of the radiological environmental surveillance measurements during calendar year 1981.

SUMMARY
1981 Environmental monitoring results showed that the radiation dose to a member of the general population did not exceed Technical Specifications of 1% of the 10 CFR 20 limit during 1981.
Radionuclides released to the air and water from Surry Station may con-tribute to the radiation background through both external and internal ex-posure.
The most significant envirorunental dose pathways are direct dose from the gaseous effluent and thyroid dose due to ingestion of milk.
The area contains only a very small milk shed which limits general population dose potential from this source and since James River water is not used for drinkinll, dose potential from this source is also minimal.
Table 4 summarizes the range and average concentrations for measurements at the indicator and control locations, and the location with the highest annual mean.
Complete information is given in the Sample Data Tables.
(Appendix I)
Specific findings for various environmental media are discussed in Section 4.

SECTION 2 SAMPLING PROGRAM
)*
5
All.samples are collected by VEPCO Environmental Services Personnel and shipped to the Eberline laboratory in West Chicago, Illinois.
Upon receipt of the samples, the laboratory staff enters the samples in a log book identifying them as to sample type, collection date, and sample code number or location, then verifies the ~pecific analyses to be performed on each sample.
The samples are then stored, awaiting analysis, on shelves expressly for this purpose to assure accountability through the laboratory processes.
Table 1 lists the sampling locations and frequencies.
shows the locations of the various sampling environs.

~,~,:t;i
'**I Table 2 lists the sample analysis program - sample class, frequency, and the type of analysis required.
Table 3 lists the LLD's (Lower Limits of Detection) for the analytical program.
These LLD's are based on Regulatory Guide 4.8.
For analyses not required in Regulatory Guide 4.8, Federal EPA, former re-quirements for similar programs, or other appropriate guides are used.
The LLD's are calculated as per RG 4.8 at the 3cr level.
The Guide specifically states that the LLD's are a priori NOT a posteriori (after the fact) limit for a particular measurement.
- When, however, RG 4.8 or other LLD's have not been achieved, a footnote giving a brief explanation has been inserted.

ANALYTICAL PROCEDURES Samples received at the laboratory are analyzed for the various radio-active components by standard radiochemical methods.
These methods are equal (1) to, and in most cases; identical with, those of the U.S.D.O.E.
or those of (2) the Federal E.P.A.
Brief descriptions of analytical procedures are available in the Labor-atory Procedures Manual available at Surry Station and the radioanalytical contractor's laboratory.
Air Particulate Filters Gross Beta - Exposed air particulate filters are counted in low back-ground Geiger or proportional flow beta counters using anti-coincidence background suppression after the short-lived naturally-cccuring radon and thoron daughters have decayed.
Filters are counted long enough to ensure that the required sensitivity (LLD) will be met Gamma Isotopic - Quarterly composites of air particulate filters are counted in high resolution (GeLi) gamma spectrometers for periods of time long enough to ensure that the required program sensitivity (LLD) is met.
(See also introduction to data tables, Section 5.)-
Water Samples (Includes Surface, Well, Precipitation, James River)
Gross Beta - A measured aliquot of sample is digested, "wet-ashed'!,
evaporated, transferred to a tared 47mm stainless steel planchet, dried, and weighed.
The planchetted sample is counted long enough in a low background beta counter to ensure that the LLD of the program will be met.

Isotopic enrichment is done by the classical method of Ostlund which involves alkaline electrolysis of a purified aliquot of sample under, controlled conditions of temperature and electrode current density.
Milk Samples I-131 -
measur.ed amounts.. of carrier. iodide are added to *a known volume of milk and the iodine extracted on anion exchange resin. The iodine is recovered and nurified by classical iodine chemistry methods which are similar to those given in former Regulatory Guide 4.3. The yield or recovery of iodine is measured gravimetrically and the precipitated sample is mounted and counted in a low level beta detector for a long enough period to ensure that the required LLD is met.
Gamma Isotopic - a measured aliquot of sample is evaporated and oven
}
dried to a standard volume and counted in a fixed geometry in a high resolution (GeLi) gamma spectrometer for a long enough period to ensure that the required LLD's are reached (see also Introduction to data Tables).
Sr-89 and Sr Stable strontium carrier is added to an aliquot of the sample which is then dried and ashed at high temperature (>700°c). The ash is dissolved and the solution treated from this point on in the same manner as are water samples (Q.v.).
Organic Samples (including Clams, Oysters, Fish, Crabs, Food Crops and Fowl).
Gamma Isotopic Analysis -
a measured aliquot of sample is oven dried or ashed as appropriate, placed in a controlled geometry and counted in a high r*esolution (Ge Li) gamma spec tromc ter for a period long enough to ensure that the LLD's of the program will be met (see also intro. to Data Tables).
17
In the case of samples such as fish and fowl, the edible flesh is sepa-rated from bones and entrails prior to drying.
Sr-89 and Sr stable strontium carrier is added to a weighed ~liquot
... of. the-sample and the -sample is ashed -at high temperature (~7-_00°c). *The
... ashed sample is.then dissolved-and processed-in the same manner as are water or milk samples.
Soil and Silt Samples Gamma Isotopic Analysis - the sample is oven dried to facilitate.handling and then sieved to remove pieces of stone and/or other large pieces of material. An appropriate sized, weighed aliquot of the sample is then transferred into a standard geometry container and counted for a period long enough to ensure that the LLD of the program will be met. (See also Introduction to Data Tables).
Thermoluminescent Dosimeters (TLD)
Environmental radiation doses are measured using badges comprizing five,
chips sealed in plastic protective holders having a density of 50 mg/cm2
- The TLD chips are l/8 11 x 1/8" x 1/32 LiF (thallium activated) known commercially as Harshaw-100. The chips are all selected to provide uniform response to-with-in 5% of the mean for the batch.
Prior.to installation, the chips are annealed by a standard cycle of 60 minutes at 400°c and immediate cooling to ambient temperature by placing the tray containing the annealed chips on an aluminum block 12" x 12" x l".
After exposure the chips are read on an Eberline Instrument Corporation Model TLR-6 reader. The system employs a preheat cycle which removes low temperature peaks and integrates and digitizes only the light output in a sel~cted temperature range.

QUALITY ASSURANCE PROGRAM A. Design of Plan Quality of product or service has always been a primary key to in-crease is sales, customer satisfaction, and profit.
The management of Eberline Instrument Corporation recognizes the ever increasing demand for higher quality and reliability for services related to protection of workers and the environment.
It is our firm belief that in order to judge the worth of a supp_ort service, one must know the philosophy behind it.
Eber-line will provide only those services for which it is qualified and these will be provided in a manner that is reliable, with a quality assurance program that maintains a high degre~ of client confidence.
This quality assurance program has been prepared consistent with the following specifications, per the Te~hnical and Quality Assurance Requirements for Special Pur~oses.
ANSI-N45.2, American National Standards Institute NRC Branch Technical Position of November 1979 NRG Regulatory Guide 4.15, Revision 1 of February 1979.
H.
lntercomparison Program Results of Eberline's Midwestern Facility participation in the USEPA's Crosscl1cck Program will be included in the monthly reports provided to the client.
Other intercomparisons in which we routinely participate include:
Environmental Protection Agency Environmental Measurement Lab DOE Quality Assessment Program Battelle Northwest Laboratories IAEA Analytical Qu:11ity Control Service US National Bureau of Standards Eberline's Albuquerque Laboratory.
Each of the laboratory managers is.responsible for preparing soikes and blanks to be run.routinely.
Every.tenth.sample is a spike, a blank, on a split sample.
Regular QC reports*are prepared by the laborary manager on a monthly 20
schedule and forwarded to eac~ client.
Each report routinely includes:
results from EIC interlaboratory comparison, resu!ts from EPA Crosscheck program, and results from other intercomparison programs.
Results are reviewed by the laboratory manager.
If a problem is in-dic:Sted by the data,- the,nature of the problem is investigated and corrective steps taken immediately.
A copy of each report is also provided to the Quality Assurance Manager of the Nuclear Services Division.
C.
Quality Assurance Plan The Quality Assurance Program follows the requirments of Company and Division Manuals.
The discussion below outlines Quality Assurance !~rograIT1s as conducted in the laboratory and as required in our QA Manual.
Procedure Approval Each procedure goes through a vigorous evaluation and review process bc(~re it is incorporated into the EIC Procedures Manual.
Established pro-cedures of the Environmental Protection Agency (EPA) or the Environmental
'i.
Measurements Laboratory of the US Department of Energy (EML) are used unless t~orough testing has demonstrated that an alternate procedure is equal to or better than the EPA or EML procedure.
Uniform procedure*s are used at both laboratories to the fullest extent possible, except when deviatipns are nccl!ssary to meet the specific requirements of the client.
The maniger of each laboratory and the quality assurance manager review and approve signif-icant procedural changes before they are implemented.
Equipment Calibration and Maintenance Equipment ~scd fur qualitative or quantit:1tivc measurements is care-fully calibrat~d~and maintained with records of each calibration or main-ten~ncc ac~ion kept in appropriate logbooks.
To the extent possible, certified standards are used for all primary calibrations.
The following standards are used for the application indicated:
21
Measurement Gross Beta Tritium Gamma
. -Spectrometry Strontium-89 and 90 Gross Alpha Radiation Dose Calibration Standard Solution of Standard 137cs certified by NBS or Amersham Searle Solution standard of 3H certified by NBS Solutfon standards of various ganuna.. emitters certified by NBS or Amersham.Searle.
Sta~dards are used to calibrate each counting geometry.used.
Solution standards of 90sr certified by Amersham Searle or NBS Solution standards of 239Pu certified by NBS or Amersham Searle.

Results of all the analyses for January through Iecember 1981 are presented in full in Section 5, Data Tables pages Table 4 summarizes the range and average concentrations for measure-ments at the indicator and control locations with the highest annual mean.
Environmental monitoring results showed that the radiation dose to a mem-ber of the general population did not exceed Technical Specifications of 1% of the 10 CF R 20 limit during 1981.
Specific findings for the various environmental media are discussed below:
1 AIR PARTICULATE SAMPLES Atmosphe_ric particulate matter at a field location is accumulated for a one-week period on a glass fiber filter using a low-volume air sampler at a collection rate of one cubic foot per minute.
This particu-late matter contained on the filter is counted for beta activity in a low-b;1ckground counting system after the short-lived naturally-occurring radon and thoron daughters have decayed.
The *gross beta particulate data obtained during the first six-month period of 1981 are higher than the data obtained during the latter half.
According to P. K. Kuroda et al 1, concentrations of Sr-89 and Sr-90 in rain ~nd sno~_~at Fayetteville, Arkansas, showed a spectacular increase during tlie-spring months of 1981 due to the 25th Chinese nuclear test
- explosio*n
- of October 1980.
It is therefore_ suggested that these higher f P. K. Kuroda, "Recent Atmospheric Injections of Nuclear Debris: Fallout from. the 16 October 1980 Nuclear Explosion", unpublished manuscript, 1981.

levels are attributable to the stratospheric fallout from this test.
The average gross beta concentration for the year for all indicator stations was 0.18 pCi/m3.
and for the control location it was also 0.18 pCi/ni3.
Data for analyses of individual filters are given on pag7-s 40 through 45 in Section 5.
The gross alpha concentrations for the** indicator and background stations remained at or below the detection limit 0.01 pCi/ni3 ~
The gamma spectrometry data of quarterly composites of air particu-late filters begins on page 46.
Traces of Ce-144, Be-7, Zr-95, Np-95, Ce-141, Ru-103, and Ru-106 were detected at both indicator and background stations and are attributable to cosmogenic origin and to the statospheric fallout from the Chinese nuclear test.
ENVIRONMENTAL DOSIMETRY Measurements of environmental dose rates were made at 43 locations on a quarterly basis using thermoluminiscent dosimeters (TLDs).
The results are tabulated on pages 47 through 48 of Section.5.
As observed in previous years, the Surry Station location displays clearly elevated dose rates throughout the year.
Other on-site ~ocations appear to be only very slightly above nearby locations and the badges located near the station intake and discharges consistently give some of the lowest readings observed.
The major fraction of the dose at the Surry Station location is undoubtedly due to operation of the station.
The doses at other on-site locations may be partially due to the station, but only by.1 few tenths of a millirem per week at most.
Doses due to the plant at locations away from the site, if they exist, are masked by doses from
,.- the- -natural environmental sources such-as uranium, thorium, and* their daughters, and possibly worldwide fallout.

PRECIPITATION SAMPLES Precipitation samples collected at the Surry Station and at Newport News are analyzed on a monthly basis and as quarterly composites
_for gross.beta depositions and tritium concentrations.
Data are sum-marized on page 50 of Section 5.
Gross beta measurements, the only measurement other than tritium required on these samples, are not capable of indicating whether the differences are due to station operations or not.
For both the control
~nd the indicator location, the gross beta data obtained during the first six-month period of 1981 are higher than the data obtained during the latter half.
These higher levels can be explained by the stratospheric fallout from the Chinese test.
The levels in general were in the range
, to be expected from measurements of these nuclides in this medium and t
there are no indications they are ~ttributable to releases from Surry
- . Station.
The tritium levels were comparable at both the indicator and control location throughout the year, and were generally in the range to be expect-ed from measurements of this nuclide in this medium.
Nevertheless, an 1111usu.illy high cont<.*ntr;1tion of tritium was found in the snmple from Surry Station during November.
It is possible that this tritium level was a result of plant operation.
However, the measured concentration was still less than 0.1 percent of the maximum permissible concentration.
MILK SAMPLES Radionuclides Cs-137 and I-131 were below the detection limits (15 pCi/1 for Cs-137 and 1 pCi/1 for I-131) for all milk samples collected
- during the year.
Sr-90 was detected in most of the milk samples in the usual low and variable concentrations-to be expected.
Sr-89 and Ba-La-140 31
were below the detection limits (5 pCi/1 for Sr-89 and 15 pCi/1 for Ba-La-140) in all samples collected.
Radioactivity attributable to operation of Surry Station was not detected in any milk samples collected during the year.
Comparisons of the average concentrations for all nuclides assayed and other statistical information are given in Table 4 and the data sum-mary on each sample by location are given on pages 51 through 53 of Section 5.
JAMES RIVER WATER SAMPLES Samples of water from the James River are collected bi-monthly from five locations including the station inlet and discharge and are analyzed for gamma emitters.
Semi-annual composites of the collections from the Chickahominy and Newport News locations are also analyzed for tritium.
Samples collected monthly from the discharge and Scotland Wharf are split with a state agency and are analyzed for tritium, Sr-89/90, and gamma emitters.
Analytical data are presented on pages 54 through 57 of*secti9n 5.
~1mma emitters were below the detection limits of this program in all samples collected.
Barely detectable concentrations of Sr-90 were found in two of the State Split discharge samples and were due to the recent Chinese bomb test.
The monthly tritium concentrations for the year for discharge samples ranged from 500 to 1000 pCi/1, the average being 848 pCi/1.
The tritium concentrations for Scotland Wharf ranged from 500 to 1700 pCi/1, the ave-rage concentration being 768 pCi/1.
There was no statistically signifi-
.. cant difference in **average concentrations between indicator and control locations.
32
Tritium levels in the semi-annual composites for Chickahominy and Newport News were slightly above the detection limit of 330 pCi/1.
These levels were in the range to be expected from measurements of this nuclide' in this medium.
"CLAM SAMPLES Clam samples are collected bi-monthly from five locations near the station including the station discharge and are analyzed for gamma emit-ters.
Samples from the station discharge are frequently designated as "State Split Samples" and such samples are analyzed for Sr-89 and Sr-90 as well as gamma emitters.
Co-60 was detected at low concentration in one sample from Hog Island Point during gamma spectroscopy analysis and could be due to r plant operations.
However, the measured concentration is still less
~han 0.1 per~ent of the maximum permissible concentration.
Analysis of state split clam samples for radiostrontium revealed the presence of only Sr-90 at levels attributable to world wide fallout in two samples.
Analytical data are presented on pages 58 and 59 of Section 5.
OYSTER SAMPLES Samples of oysters are collected from Deep Water Shoal, Point of Shoal, and Newport News on a bi-monthly basis and analyzed for gamma emitters.
A~alytical data are presented on page 60 of Section 5.
Gamma emitters were below the detection limits of the program in all samples collected throughout the year.
33
FISH SAMPLES Fish samples are collected in the vicinity of the station twice a year and analyzed for gamma emitters.
Data are presented on page 61 of Section 5 *
. Gamma emitters were below the detection limits of the program specifications.
CRAB SAMPLES Samples of crab from the vicinity of Surry Station are collected during the summer months and analyzed for gamma emitters.
The gaIJUila emitters were below the detection limits of the program and are listed on page 61 of Section 5.
SILT SAMPLES Silt samples were collected three times during 1981 from six loca-tions (five indicator and one control location) and analyzed for gamma emitters.
Silt is one of the few environmental media in which radioactive effluents from nuclear power stations are usually detected.
Traces of Cs-137 were found in most samples.
The presence of this nuclide is attributed to world wide fallout from atmospheric nuclear tests.
Several indicator samples also contained Co-60, Cs-134, Zr-95, Nb-95, Co-58, and Mn-54 above the detection limit.
Their presence could be due to station operations.* Data are summarized on page 62 of Section 5.
SOlL SAMPLES Soil samples are collected annually from six locations and analyzed by gamma spectrometry for gamma emitters
- The only nuclide detected at concentrations greater than the detection' 34
limit for the program was Cs-137.
The concentrations of Cs-137 have been quite variable throughout the years as is illustrated in the table below.
This is probably due to the well-recognized difficulty *of ob-
- ta~ning truly representative samples of soil.
Modified sampling tech-niques by station personnel appear to have eliminated this problem from 19,8 to the present.
There are no clear trends and the origin of the cesium is unclear.

Long and short term world wide fall.out are probably the major factors but contributions to the total by the station cannot be ruled out.
If, however, the major fraction were due to the station, significant amounts of Cs-137 and Co-60 might be expected in the samples, but this is not the case.
Detailed nnnlytical dntn arc presented on page 63 of Section 5.
FOWL SAMPLES A coot from the Hog Island Reserve was collected in March and a goose was obtained from the same area in September.
They were analyzed for gamma emitt~~s, specifically for Cs-134 and Cs-137.
Concentrations of these nuclides were below the detection limit of 80 pCi/kg for both samples.
Data are given on page 63 of Section 5.

CROP SAMPLES Samples of food cro_ps (kale, cabbage, corn, peanuts, and soybeans) were collected from four area farms in 1981 and analyzed from gamma emit-ters, Sr-89, and Sr-90.
Gamma emitters and-Sr-89 were below the detection limits of the program.
Sr-90 was detected in most of the samples in low and variable con-centrations.
Long and short ter~ world wide fallout deposits are probably the reason for this.
The results are tabulated on page 63 of Section 5.
WELL WATER SAMPLES Samples.of water were collected from each of four wells (three indicat<>r and one control location) once in April and once in October.
These were analyzed for gross alpha, gross beta, and tritium.
Gross alpha and beta activity were detected in most of the samples at the usual low levels encountered in environmental media.
There was no statistically significant difference in concentrations, which were similar to those measured previously, between indicator and background st.1tions and the activity is attributable to naturally occurring nuc-lid es.
Tritium concentrations were at or below the detection limits in samples collected during the year.
Analytical data are given on page 64 of Section 5.
SURFACE WATER SAMPLES Surface water samples were collected in April and October from
.. each of four locations.
They were analyzed for gross alpha, gross beta, and tritium.
36
- Gross alpha and gross beta levels were ~11 at the low concentrations usually expected to be found in environmental surface water, with no sig-nificant differences between indicator and background stations or concen-
'tr~tions measured in the.previous years.
Tritium concentrations were at the detection limits of the program
- in spring collections, and below *the detection limits in the fall.
The levels of tritium measured were comparable at both indicator and back-ground locations, and were generally in the range to be expected from measurements of this nuclide in this medium.
Data are presented oh page 64 in Section 5.

used in place of a concentration when a sample was not available (NS), or when a sample was not analyzed for some specific measurement (NA), or when an analysis is not required (NR).
figures following 11+/-11 are error terms based on counting uncertainties at the 2a (95% confidence) level.
Values pre-ceded by the"<" symbol were below the stated concentration
.at the 3a (99% confidence) level.
Exponents necessary to prevent data tables from being cumbersome are handled in the conventional manner of including them in the column headings.
In general, all analyses meet the sensitivity requirements of the program as given in Table 3.
For the few samples that do not (because of inadequate sample quantities, analytical
-interferences, etc.)- the sensitivity actually obtained in the analysis is given.
when all analyses of a particular type during the period resulted in concentrations below the sensitivity limits, a statement is*made on the -appropriate table rather than presenting a whole page of"<" data.
If all but one or two data points are below the sensitivity limits, the previously mentioned convention is followed and the finite data are given as footnotes.
