1.0 INTRODUCTION

This report summarizes the Environmental Radiological Monitoring Program conducted for the Arkansas Nuclear One - Units. 1 and 2 during the calendar year 1984. All samples analyses and data interpretation were performed by the staff of Arkansas Power and Lir,ht Company.

1.1 PLANT AND LOCATION Arkansas Nuclear One - Units 1 and 2 are both lightwater cooled pressurized water nuclear reactors located approximately 5.0 miles west of Russellville, Arkansas. ANO Unit 1 began commercial operation in December 1974 and the second unit at the same site, ARO Unit 2, followed in March 1980. Lake Dardanelle is the source of the circulating cooling water for ANO Unit 1, and ANO Unit 2 is cooled by a cooling tower, also dependent upon Lake Dardanelle water.

1.2 ENVIRONMENTAL MONITORING PROGRAM The Environmental Monitoring Program was established based upon the Environmental Technical Specifications for ANO Unit 1. These specifications have remained essentially the same, except for the addition and deletion of sampling stations where milk, ground water, or food products are collected. The 1984 Environmental Radiological Monitoring Report was governed by environmental technical 1

i specifications in effect through December 31, 1984. The 1984 report includes summaries, interpretations, and statistioal evaluation of the results of the radiological environmental surveillance activities at ANO. Table 1-1 details the surveillance program listing sample type, frequency of collection, and the method of analysis used. Table 1-2 lists the sample location and type of samples collected at each location.

1.3 CONTROL LOCATIONS During the calendar year 1984, the following locations were designated as control stations along with the respective sample type and analysis:

a) AP&L's Substation at Danville, Arkansas (Station #7)

, 1) Air Particulate

2) Air Iodine

3) Precipitation i

4) Vegetation

5) Soil

6) TLD 2

I

b) Piney Creek Area (Station #16) 4

1) Lake Water

2) Bottom Sediment

3) Aquatic Biota (including fish) c) R. A. Young's Dairy (Station #23)

1) Milk

2) Vegetation 2.0 INTERPRETATIONS AND CONCLUSIONS Data collected from radiological analyses, of environmental samples collected in the area surrounding the ANO facility, indicates no detectable environmental impact in excess of design objectives as a result of liquid and gaseous discharges from the ANO site during 1984.

Also, no non-routine environmental radiological monitoring reports resulting from analyses of environmental samples were submitted to the U.S. NRC during 1984.

Sample types that indicated activation or fission produced radioisotopes present are discussed in the paragraphs below.

4 2.1 SAMPLES ASSOCIATED WITH AIR MONITORING None of the 312 samples collected from indicator locations for radiciodine in air (using activated charcoal filters) indicated iodine-131 activities greater than the lower limit of detection, which is 0.050 pCi per cubic meter of air.

Also, none of the 77 monthly composites of air particulate filters analyzed in the calendar year 1984, including the control air particulate samples from Danville, Arkansas indicated the presence of radioactive fission or activation products.

TLD data collected for the calendar year 1984 is divided into two categories. The first category includes the lithium fluoride (LiF)

TLDs which were collected and read quarterly, and the second category includes (LiF) TLDS which were collected and read semiannually. The quarterly TLD data for 1984 indicated a total yearly average dose for the forty-three indicator locations to be 68 mrom per year compared to the total yearly average dose of 70 mrem for 1983 and 63 mrom for 1982.

The control location at Danville, Arkansas (109' - 19.3 elles) indicated a total dose, based upon quarterly TLDs, of 67 mrem per year for 1984 compared to 56 mrem for 1983 and 59 mrom per year for 1982.

Table 2.1.1 IIsts the total yearly average dose for the indicator location for the calendar years of 1981, 1982, 1983, and 1984 compared to the total dose of background radiation (control station), also based upon quarterly TLD reports.

The difference between the indicator locations and the centrol location for 1984 quarterly TLDs results is not statistically significant. The standard deviation for the indicator locations is 5.1 mrem annual dose.

For a one sample t-test, (i.e., a single control compared to all indicator locations), a t-value of 0.77 is obtained. This t-value does not indicate a significant difference between the control and indicator locations at the 95% confidence level. A t-value of greater than 1.96 would be necessary to indicate a significant difference.

Factors other than statistical fluctuations that may affect the variation in recorded dose include variations of up to 15% in response of the TLD chips to the same radiation exposure, different soil types at monitoring locations, and varying heights above ground level for TLD placement.

The TLDs collected every six months during 1984 indicated slightly lower readings than the quarterly TLDs, which is consistent with TLD readings recorded in 1983, 1982, 1981, and 1980. The lower dose measurement for the dosimeters deployed in the field for six months compared to the quarterly readings is attributed to " fading" of the lithium fluoride chips. The TLDs collected every six months indicated a total yearly average dose for the indicator locations of 56 mrem, compared to 57 mrem per year in 1983 and 48 mrem per year in 1982. The six-month TLDs are located at six indicator locations and one control location. The control location indicated a total dose, base upon TLDs collected and read semiannually, of 61 mrem, compared to 58 mrem in 1983.

22

The small difference in six month 1984 TLD data between indicator locations and control location is not significant. The standard deviation for the indicator locations is 10.6 mrem annual dose. A t-value of -0.75 is calculated for a single sample t-test comparing the indicator locations to the control. At the 95% confidence level at t-value of greater than 2.20 would be necessary to indicate any statistically significant difference.

None of the 126 rain samples collected and analyzed in 1984, as in 1982 and 1983, indicated the presence of radioactive fission or activation products. Analyses performed were gamma spectrometry and gross beta.

2.2 SAMPLES ASSOCIATED WITH WATER MONITORING Lake water samples are collected from five different sample sites in Lake Dardanelle monthly, plus the Arkansas Department of Health and Arkansas Power and Light Company split a surface water sample from the ANO Discharge Canal and Piney Bay monthly. Each laboratory analyzes the sample of gamma emitters. One surface water sample with measurable quantities of plant related gamma-emitting radionuclides was collected from the ANO Discharge Canal. This surface water grab sample was collected by and split with the Arkansas Department of Health on May 8, 1984 at 10:59 a.m. Approximately 35 pCi/l of Co-58 and 13 pCi/l of Co-60 were detected in the May 1984 split sample from the ANO Discharge Canal. No dose calculation was calculated for this sample since this area of Lake Dardanelle is not a source of drinking water.

23

h As in previous years, bottom sediments collected from the ANO Discharge Canal (0.1 mile 180*) during 1984 indicated the greatest concentration of radionuclides attributable to ANO operations. To determine the maximum whole body dose exposure from sediments, dose calculations were performed according to the mathematical model for determining external 1

dose from sediment given by U.S. Nuclear Regulatory Commission Regulatory Guide 1.109. Tables 2.2.1 and Table 2.2.2 give the results of these calculations for samples collected from the ANO Discharge Canal in February and August 1984. The maximum external dose to the

~ skin from sediments for all measurable radionuclides was approximately 0.20 .irem per year, and the maximum whole body dose was approximately 0.16 mrem per year.

According to ANO Technical Specifications, the design objectives for the dose to the whole body or any organ of an individual is 5 arem per l year as the result of release of liquid wastes. The value of 0.2 mrem per year for maximum whole body dose or maximum external dose to skin of a teenager is well within the design objective criteria.

The 1984 fish samples collected include the three categories listed in l previous annual environmental radiological reports: 1) bottom feeder l

fish, usually buffalo and carp, 2) carnivorous fish, usually catfish, crappie and bass, and 3) plankton feeder fish, usually shad. Edible portions of bottom feeder and carnivorous fish and whole plankton feeder fish are analyzed by gamma spectrometry for radionuclides. The highest level of reactor produced radionuclides attributed to operations at ANO were found in whole plankton feeder fish collected September 4, 1984 from the ANO Discharge Canal (0.1 mile 180*).

J Dose calculations based upon the plankton feeder fish radioisotope concentrations were found according to the mathematical model for determining maximum total dose to total body from fish consumption given by the U.S. NRC Regulatory Guide 1.109. Although, shad are forage for carnivorous fish species, for this calculation it was assumed that shad serve as human food. Table 2.2.9 identifies the radioisotopes found in the plankton feeder fish, the amount of radioactivity present, and the contribution of the total maximum calculated dose for either whole body or specific body organs.

According to these calculations, the maximum dose to adults to total body from plankton feeder fish consumption is about 1.1 mrem per year to the liver. The value of 1.1 mrem per year is well within the design objective criteria of 5 mrem per unit as defined in the AN0 Technical Specifications for liquid wastes.

Tables 2.2.3 through 2.2.10 identifies all radioisotopes found in eight fish samples collected and analyzed in 1984. According to dose calculations given in U.S. NRC Regulatory Guide 1.109, the bottom feeder fish collected from the ANO Discharge Canal on September 4, 1984 revealed the highest dose from edible fish samples collected in 1984.

The calculated maximum organ dose was 0.61 mrem per year (liver).

In addition to the fish samples described above, edible portions of fish were collected by the Arkansas Department of Health, on May 10 and October 4, 1984. Edible portions of fish collected from the ANO Discharge Canal October 4, 1984 contained the highest levels of reactor produced radionuclides for these split fish samples. In Table 2.2.3 and 2.2.4, dose calculations were performed according to 97 l

the mathematical model given by U.S. NRC Regulatory Guide 1.109. The highest calculated dose to adults from consumption of fish split with the Arkansas Department of Health is 0.32 mrem per year (liver).

l Table No. 2.2.11 is a listing of concentrations of radionuclides 4

detected in sport fish tissue samples split with the Arkansas Department of Health collected during the calendar years 1978, 1979, 4 1980, 1981, 1982, 1983, and 1984. Figures 2.2.1 and 2.2.1 graphically depicit the Cs-134 and Cs-137 concentrations given in Table 2.2.11.

The Spearman rank-correlation test was applied to the Cs-134 and Cs-137 activity concentrations in sport fish tissue given in Table 2.2.11.

Data of sample collection and activity concentration was ranked and the i

correlation calculated to determine if a significant increasing trend of activity concentration versus time has occurred during the seven year period of 1978 through 1984. The calculated Spearman ranked-correlation coefficient for Cs-134 is 0.372. At the 95%

confidence level the Spearman coefficient would have to be greater than 0.506 for twelve observations to indicate a positive correlation of Cs-134 activity concentration with time. Similarly, the Spearman coeficient for Cs-137 is 0.503. The Spearman rank-correlation coefficient for Cs-139 approaches the 95% confidence level for indication of increasing activity concentration with time. Additional data collected in 1985 will provide a greater data base to evaluate the activity concentration of Cs-137 in fish tissue with time.

i Whole mollusks samples were collected in April and October 1984.

Samples of mollusks caged in the ANO Discharge Canal (0.1 mile 180 ) {

indicated reactor produced radionuclides present. Reactor produced radionuclides found include Cobalt-58, Cesium-134, and Cesium-137.

1 Radionuclide concentrations in mollusks are comparable to fish l concentrations discussed above.

2.3 SAMPLES ASSOCIATED WITH TERRESTRIAL MONITORING 1

Milk samples were collected by the split with the Arkansas Department of Health in all twelve months of 1984. Three indicator locations for collection of milk at dairies and one control location, the R. A. Young Diary (12.0 miles 73 ), were active during 1984.

Monthly milk samples are analyzed for Iodine-131 by concentrating the

'T iodine with anion exchange resin and counting the concentrated iodine sample in a low-background alpha / beta counting system.

No gamma emitting radionuclides were detected by gamma spectrometry in milk samples collected in 1984, including the R. A. Young Dairy, the control dairy.

Strontium-89 and Strontium-90 analyses in milk produced average strontium activities at indicator locations equivalent to 1983, 1982 and 1981 levels.

Vegetation samples were divided into two categorios in 1984, pasturage vegetation and garden products vegetation. Of the 33 pasturage samples collected and analyzed in 1984, cesium-137 was the only gamma emitting radionuclide determined in pasturage samples. Cesium-137 was detected in two samples from indicator locations and in one control sample from Danville, AR. Garden products vegetation was collected in May, June, July, August, and September 1984 from two gardens. Garden vegetation collected and analyzed included cabbage, head lettuce, spinach, and leaf lettuce. No gamma emitting radionuclides were detected in any garden products vegetation during 1984.

Soil samples were collected in May and November 1984 from seven sampling stations each time. Cesium-137 was detected in all fourteen soil samples. Due to its wide spread presence international fallout is the probable source of this fission produced radionuclide.

Manganese-54 was detected in the soil sample taken in May 1984 at sampling site no. 2 (0.5 miles 235'); however, the activity concentration was less than the "a prior" LLD for this isotope. Only cesium-137 was detected at this location during the November 1984 sampling period.

2.4 SAMPLES NOT COLLECTED IN 1984 Caged mollusks were sampled in 1984 as representatives of benthic organisms. It is impossible to place a cage at location 15, the Dardanelle Dam area, because of the water depth. Naturally occurring benthos are not present in quantities sufficient for analysis, therefore, no benthic organisms were analyzed at sample station No. 15.

41

Most of the caged mollusks in the ANO Discharge Canal collected in October, 1984 were dead upon retrieval and only the shells remained.

Gamma analysis was performed on the shells of these deaa mollusks.

The April 1984 air particulate composites (7 composite samples collected for four weeks) were accidentally destroyed by Strontium analysis before gamma spectrometry was performed. However, gross alpha and gross beta analysis of each individual air particulate sample indicated no results higher than usual from the April 1984 air particulate samples.

On January 11, 1984, precipitations samples at sample stations No. 5 and No. 7 were frozen, and again on January 19, 1984, precipitation samples were frozen at sample stations No. 1, 3, 5, and 7. Freezing prevents removal of the sample from the sample collection device.

Air sampling equipment was not functional upon return to collect weekly air particulate and air iodine samples at the following dates and locations:

August 1, 1984 - Sample Station No. 3 September 19 1984 - Sample Stations No. 1 and 4 November 11, 1984 - Sample Station No. 7 November 28, 1984 - Sample Station No. 7 December 12, 1984 - Sample Station No. 7 December 26, 1984 - Sample Station No. 5 42

2.5 COMPARISON OF RESULTS OF EPA CROSS-CHECK PROGRAM The Technical Analysis Section of Arkansas Power and Light Company participates in the U.S. Environmental Protection Agency's Environmental Radioactivity Laboratory Intercomparison Studies Program.

The major objective of this program is to assist laboratories involved in environmental radiation measurements to develop and maintain both an intra-laboratory and an inter-laboratory quality control program. This is partially accomplished through a laboratory intercomparison studies program involving environmental media (milk, water and air) and a variety of radionuclides with activities at or near environmental levels.

During the calendar year 1983, the following sample types were received and analyzed:

1) Gross Alpha-Beta in Water - A one-liter sample for the analysis of gross alpha and gross beta activity.

2) Gamma in Water - A one-liter sample containing chromium-51, zinc-65, cobalt-60, ruthenium-106, cesium-134 and cesium-137.

3) Tritium in Water - A twenty-five m1 sample containing tritium.

4) Iodine-131 in Water - four-liter sample containing iodine-131.

43

5) Strontium in Water - A one-liter sample containing strontium-89 and strontium-90.

6) EPA Blind in Water - A one-liter blind sample containing a mixture of radionuclides.

7) Milk - Four-liter milk sample containing potassium, strontium-89,

strontium-90, iodine-131, cesium-137 and barium-140.

l

8) Air - A two-inch diameter air filter is distributed quarterly for

] gross alpha, gross beta, cesium-137 and strontium-90 analyses.

4 i

a

9) Low-Level Water - A four-liter sample containing very low l

quantities of I-131.

10) Low-Level Milk - A four-liter sample containing very low quantities of I-131.

A report listing the results of the analysis containing the laboratory standard deviation, calculation of the normalized range, normalized I

deviation, sample standard deviation, and the grand average of all laboratories is mailed after each participating laboratory performs three independent determinations for each radionuclide involved in the study, i

i t

44

Table 2.5.1 lists the various analyses that are performed, the radioactivity levels found in the EPA cross-check samples, and one standard deviation for a single determination.

If the Technical Analysis Section Environmental Laboratory results differ by more than 3 standard deviations from the known results given in the EPA cross-check reports, the instrument and procedure are checked for error.

Table 2.5.2 lists the date of preparation, types of EPA cross-check samples received, the total number of analyses performed, the average sample standard deviation based upon three independent determinations for each radionuclide in each sample, and the number of standard deviations the AP&L lab differed from the known value.

Most of the results were well within three standard deviations of the known values supplied by the U.S. EPA.

Results from analyses for strontium-90 in EPA milk samples were outside

the control limit of 3 standard deviations for the June 22 and October 26, 1984 samples. Radiostrontium analyses have been deleted from the monitoring program for 1985 and the investigation to identify the source of the disagreement with the EPA values has been i

discontinued.

d5 i i

Gross beta results in EPA air filters differed from the known values by approximately 3 standard deviations in the August 24 and November 23, f

1984, samples. The mixture of isotopes in the EPA sample produces a different beta energy mix compared to the calibration source. New air filter efficiency curves for 1985 will include Sr-90 and Cs-137 to compensate for the energy differences.

3.0 PROGRAM TECHNICAL DESCRIPTION 3.1 SAMPLE HANDLING AND TREATMENT Once a representative sample is collected and delivered to the laboratory, the laboratory staff is responsible for properly treating and storing the sample. Often samples collected in an environmental !

4 survey require treatment because they are not physically ready for j analysis. Treatment of the sample after it is received depends on the sample itself and the analyses to be performed on it. Most treatment and handling techniques have been established and well known for many years.

i L Water Samples Generally, water samples are acidified when collected. If tritium analysis is to be performed, portions for these analyses are separated before acid is added. Samples for tritium analyses should not be stored in polyethylene bottles for more than 3 or 4 months because water can evaporate through the polyethylene. If the samples are to be stored for sny length of time, carrier or complexing agents should be added to prevent adsorption of trace metals on the storage containers.

51 l

l l

l Air Filters The air filter must be handled with care when heavy dust loadings is observed because particulate matter is easily removed from the filter.

Air filters are often received by the laboratory in envelopes; some I l l l

extremely low-level analyses may require analysis of the envelope in i which the sample arrived as well as the sample itself.

I l

Milk Milk samples are refrigerated until analyses can be performed. If the analyses will be delayed for more than a few days, a preservative

, (formalin) is added to inhibit bacterial growth and retard spoilage.

Milk samples that are to be analyzed for 131 I have 100 m1 formalin l

l added to avoid binding of the iodine that may occur with smaller levels of formalin.

1 Soil and Botton Sediments Soil samples are dried, pulverized, and sieved to pass a 200 mesh sieve before analysis. Further thorough mixing is required to ensure a homogeneous sample.

.52

Other Samples Perishable samples.are preserved by refrigeration or freezing.

Vegetation and other samples may need to be dried, pulverized, or ashed before analysis.

3.3 DETERMINATION OF GROSS ALPHA AN0/0R GROSS BETA ACTIVITY IN WATER SAMPLES (SUSPENDED AND DISSOLVED PORTIONS)

This describes the process used to measure the overall alpha and beta radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved. Two hundred al of the sample is evaporated in a beaker at approximately 100'C. The residue is transferred and dried and in a 2-inch stainless steel planchet.

The planchets are counted for 100 minutes in a low-background alpha-beta counting system. Calculation of activity includes a self-absorption correction for counter efficiency based on the weight of residue on each planchet.

3.5 ANALYSIS OF SAMPLES FOR 10 DINE-131 Milk or Water Up to four liters of sample are thoroughly mixed with a stable iodir.e carrier solution. The sample is then allowed to flow through an anion exchange resin column to remove iodine from the sample. The iodine is then stripped from the resin with sodium hypochlorite solution, is reduced with hydroxylamine hydrochloride and is extracted into carbon tetrachloride as free iodine. It is then back-extracted into sodium bisulfite solution and is precipitated as silver iodide. The precipitate is weighed for chemical yield and is mounted on a stainless steel planchet for low-level beta counting. The chemical yield is corrected by measuring the stable iodide content of the milk or the water with a specific ion electrode.

Calculations of the results, two sigma error and the lower limit of detetection (LLD) in pCi/A:

RESULT = (N/At-B)/2.22*EaVeYeexp(-A^t2 )

TWO SIGMA ERROR =(2i(N/At+B/At)+(2.22*E*VeY*exp(-AAt)) 2 LLD = (4.66 h/At) (2.22*E*VeYeexp(-AAt2 ))

3.6 GAMA SPECTROMETRY OF SAMPLES Milk and Water A 3.5 liter Marinelli beaker is filled with a representative aliquot of the sample. The sample is then counted for a minimum of 450 minutes with a shielded Ge(Li) detector coupled to a multi-channel analyzer.

Vegetation, Food and Garden Crops, and Fish As much as possible a vegetation food, or garden crop sample, without drying, is loaded into a tared 3.5 liter Marinelli beaker and weighed.

The sample is then counted for a minimum of 450 minutes with a shielded Ge(Li) detector coupled to a computer-based data acquisition system which performs pulse height analysis. As much as possible (up to the total sample) of the edible portion of a fish is loaded into a tared Marinelli beaker add weighed. The sample is then counted for a minimum of 450 minutes with a shielded Ge(Li) detector coupled to a computer-based data acquisition system which performs pulse height analysis.

3.7 CHARC0AL CARTRIDGES Charcoal cartridges are counted in a Marinelli Beaker, with one cartridge positioned on the face of a Ge(Li) detector and up to six cartridges on the side of the Ge(Li) detector. Each Ge(Li) detector is calibrated for both positions. The detection limit is determined for I-131 of each charcoal cartridge, assuming no positive results for I-131, for each unique cartridge from the volume of air which passed through it. If Iodine-131 is observed in the screening count of a set of cartridges, each charcoal cartridge is then counted separately, positioned on the face of the detector. A separate counting geometry has also been established for each Ge(Li) detector.

Air Particulate The four or five (depending on the calendar month) air particulate filters for a monthly composite for each field station are stacked one on top of another and then counted for at least four hours with a

{

shielded Ge(Li) detector coupled to a multi-channel analyzer.

A computer software program defines peaks by certain changes in the slope of the spectrum. The program also compares the energy of each peak with a library of peaks for isotope identification and then performs the radioactivity calculation using the appropriate fractional fi3

gamma ray abundance, half life, detector efficiency, and net counts in the peak region. The calculation of results, two sigma error and the lower limit of detection (LLD) in pCi/ volume or pCi/ mass:

RESULT = (S-B)/(2.22*T*E*V*F)

TWO SIGMA ERROR = (2 4S+B)/(2.22*T*E*V*F)

LLD = (4.66 6 /(2.22*T*E*V*F) where: S = Area, in counts, of sample peak and background (region of spectrum of interest)

B = Background area, in counts, under sample peak, determined by a linear interpolation of the representative backgrounds on either side of the peak.

T = length of time in minutes the samples was counted 2.22 = dpe/pCi E = detector efficiency for energy of interest and geometry of sample V = sample aliquot size (liters, cubic meters, kilograms, or grams)

F = Fractional gamma abundance (specific for each emitted gamma 6dl

i 3.8 TERMINOLOGY OF QUALITY CONTROL OF DATA mean: The sum of the test results divided by the number of results taken; that is, X = X /n,4 where X = mean, X4 = individual result, and n = number of results precision: A measure of the reproducibility among replicate observations.

variance: The sum of the squares of deviations of the test results from the mean after division by one less than the total number of n

results; that is, VAR = [ (X - X9 ) 2/(n - 1).

i=1 standard deviation: The square root of the variance; that is,

'n

~

o = (VAR)b = 1(X-X)2/(n-1) 4 b

i=1 ,

range: The difference between the highest test result and the lowest test results in a set of observations.

(15 P

accuracy: A measure of the agreement between observed and accepted values, systematic error: Errors that may be traced to the personal errors of the analyst instrumental errors, errors that inherently aro in the analytical methodology, or a combination of these.

Accuracy is a measure of type of or error, random error: The necessity for making estimations is inherent in the process of collecting data for the measurement of any quantity. For this reason, any measurement will be uncertain, in an amount that depends on the relative magnitude of the estimations involved in its evaluation.

Careful experimental design can reduce this uncertainty; however, small irreducible variations will remain. Since radioactive decay is a random process, any counting measurement will have a random error associated with it.

Precision measures this type of variability or error, bias: The difference between the average of a set of test results and the accepted value. Bias usually is indicated only when 4

a consistent difference is observed over time and can be corrected for by the application of appropriate correction factors. Bias is a measure of the systematic error.

3.9 LLD CALCULATION The LLD is the smallest concentration of radioactive material in a sample that will be detected with 95% probability with only 5%

probability of falsely concluding its presence.

LLD = 4.66(sg )

E

2.22

Y

exp(-Aat) i where:

. LLD is the lower limit of detection as defined above (as pCi per unit mass or volume)

, s b is the standard deviation of the background counting rate or of

! the counting rate of a blank sample as appropriate (as counts per minute)

E is the counting efficiency (as counts per transformation)

(57 i

V is the sample size (in units of mass or volume) 2.22 is the number of transformation per minute per picocurie Y is the fractional radiochemical yield (when applicable)

A is the radioactive decay constant for the particular radionuclide At is the elapsed time between sample collection and analysis The value of sb used in the calculation of the LLD for a detection system shall be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the background shall include the typical contributions of other radionuclides normally present in the sample (e.g. , potassium-40 in milk samples).
