SUMMARY

This Annual Radiological Environmental Operating Report describes the Catawba Nuclear

Station Radiological Environmental Monitoring Program (REMP), and the program results

for the calendar year 2013.

Included are the identification of sampling locations, descriptions of environmental sampling 0and analysis procedures, comparisons of present environmental radioactivity levels and pre-0operational environmental data, comparisons of doses calculated from environmental measurements and effluent data, analysis of trends in environmental radiological data as 0potentially affected by station operations, and a summary of environmental radiological 0sampling results. Quality assurance practices, sampling deviations, unavailable samples, and program changes are also discussed.

0Sampling activities were conducted as prescribed by Selected Licensee Commitments

(SLCs). Nine-hundred thirty-four samples were analyzed comprising 960 test results in order to compile data for the 2013 report. Based on the annual land use census, the current number 0 of sampling sites for Catawba Nuclear Station is sufficient.

Concentrations observed in the environment in 2013 for station related radionuclides were generally within the ranges of concentrations observed in the past. Inspection of data showed that radioactivity concentrations in fish are higher due to surface water tritium levels than the 0activities reported for samples collected prior to the operation of the station. Measured concentrations were not higher than expected and all positively identified measurements attributable to station operation were within limits as specified in SLCs.

Additionally, environmental radiological monitoring data is consistent with effluents 0introduced into the environment by plant operations. The total body dose estimated to the maximum exposed member of the public as calculated by environmental sampling data,

excluding TLD results, was 1.63E-02 mrem for 2013. Background radiation dose in the

United States is approximately 620 mrem per year (approximately half from naturally occurring sources such as radon and half from man-made sources such as medical processes)

(reference 6.13). It is therefore concluded that station operations has had no significant

radiological impact on the health and safety of the public or the environment.

2.0 INTRODUCTION

2.1 SITE DESCRIPTION AND SAMPLE LOCATIONS 0Duke Energy Corporation's Catawba Nuclear Station is a two-unit facility located on the shore

of Lake Wylie in York County, South Carolina. Each of the two essentially identical units employs a pressurized water reactor nuclear steam supply system furnished by Westinghouse

Electric Corporation. Each generating unit is designed to produce a net electrical output of approximately 1145 MWe. Units 1 and 2 achieved initial criticality on January 7, 1985, and

May 8, 1986, respectively.

Condenser cooling is accomplished utilizing a closed system incorporating cooling towers, instead of using lake water directly. Liquid effluents are released into Lake Wylie via the station discharge canal and are not accompanied by the large additional dilution water flow associated with "once-through" condenser cooling. This design results in greater radionuclide concentrations in the discharge canal given comparable liquid effluent source terms.

Figures 2.1-1 and 2.1-2 are maps depicting the Thermoluminescent Dosimeter (TLD) 0monitoring locations and the sampling locations. The location numbers shown on these maps

correspond to those listed in Tables 2.1-A and 2.1-B. Figure 2.1-1 comprises all sample

locations within a one mile radius of CNS. Figure 2.1-2 comprises all sample locations within a 10 mile radius of CNS.

2.2 SCOPE AND REQUIREMENTS OF THE REMP 0An environmental monitoring program has been in effect at Catawba Nuclear Station since

1981, four years prior to operation of Unit 1 in 1985. The preoperational program provides

data on the existing environmental radioactivity levels for the site and vicinity which may be used to determine whether increases in environmental levels are attributable to the station. The operational program provides surveillance and backup support of detailed effluent monitoring 0which is necessary to evaluate the significance, if any, of the contributions to the existing 5environmental radioactivity levels that result from station operation.

This monitoring program is based on NRC guidance as reflected in the Selected Licensee SCommitments Manual, with regard to sample media, sampling locations, sampling frequency and analytical sensitivity requirements. Indicator and control locations were established for comparison purposes to distinguish radioactivity of station origin from natural or other "man-made" environmental radioactivity. The environmental monitoring program also verifies Sprojected and anticipated radionuclide concentrations in the environment and related exposures 0from releases of radionuclides from Catawba Nuclear Station. This program satisfies the requirements of Section IV.B.2 of Appendix I to 10CFR50 and provides surveillance of all appropriate critical exposure pathways to man and protects vital interests of the company, public and state and federal agencies concerned with the environment. Reporting levels for 0

activity found in environmental samples are listed in Table 2.2-A. Table 2.2-B lists the REMP analysis and frequency schedule.

The Annual Land Use Census, required by Selected Licensee Commitments, is performed to ensure that changes in the use of areas at or beyond the site boundary are identified and that modifications to the REMP are made if required by changes in land use. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10CFR50. Results are shown in Table 3.11.

Participation in an interlaboratory comparison program as required by Selected Licensee Commitments provides for independent checks on the precision and accuracy of measurements of radioactive material in REMP sample matrices. Such checks are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10CFR50. A summary of the results obtained as part of this comparison program are in Section 5 of this annual report.

2.3 STATISTICAL AND CALCULATIONAL METHODOLOGY 2.3.1 ESTIMATION OF THE MEAN VALUE There was one (1) basic statistical calculation performed on the raw data resulting from the environmental sample analysis program. The calculation involved the determination of the mean value for the indicator and the control samples for each sample medium. The mean is a widely used statistic. This value was used in the reduction of the data generated by the sampling and analysis of the various media in the Radiological Environmental Monitoring Program. "Net activity (or concentration)" is the activity (or concentration) determined to be present in the sample. No "Minimum Detectable Activity", "Lower Limit of Detection", "Less Than Level", or negative activities or concentrations are included in the calculation of the mean. The following equation was used to estimate the mean (reference 6.8):

N X -- = Exi i=1 N

Where:

x = estimate of the mean, i = individual sample, N = total number of samples with a net activity (or concentration),

Xj = net activity (or concentration) for sample i.

0 2.3.2 LOWER LEVEL OF DETECTION AND MINIMUM 0DETECTABLE ACTIVITY

The Lower Level of Detection (LLD), and Minimum Detectable Activity (MDA) are

used throughout the REMP.

LLD - The LLD, as defined in the Selected Licensee Commitments Manual is the smallest concentration of radioactive material in a sample that will yield a net count,

above the system background, that will be detected with 95% probability with only 5%

probability of falsely concluding that a blank observation represents a "real" signal.

The LLD is an a priorilower limit of detection. The actual LLD is dependent upon the

standard deviation of the background counting rate, the counting efficiency, the sample size (mass or volume), the radiochemical yield and the radioactive decay of the sample

between sample collection and counting. The "required" LLDs for each sample medium and selected radionuclides are given in the Selected Licensee Commitments 0*and are listed in Table 2.2-C.

MDA - The MDA is the net counting rate (sample after subtraction of background) that must be surpassed before a sample is considered to contain a scientifically measurable amount of a radioactive material exceeding background amounts. The MDA is 0calculated using a sample background and may be thought of as an "actual" LLD for a particular sample measurement.

0 2.3.3 TREND IDENTIFICATION 0One of the purposes of an environmental monitoring program is to determine if there is a buildup of radionuclides in the environment due to the operation of the nuclear station. Visual inspection of tabular or graphical presentations of data (including preoperational) is used to determine if a trend exists. A decrease in a particular radionuclide's concentration in an environmental medium does not indicate that reactor operations are removing radioactivity from the environment but that reactor operations are not adding that radionuclide to the environment in quantities exceeding the preoperational level and that the normal removal processes (radioactive decay, 0deposition, resuspension, etc.) are influencing the concentration.

S

Substantial increases or decreases in the amount of a particular radionuclide's release from the nuclear plant will greatly affect the resulting environmental levels; therefore, a knowledge of the release of a radionuclide from the nuclear plant is necessary to 0completely interpret the trends, or lack of trends, determined from the environmental data. Factors that may affect environmental levels of radionuclides include prevailing

weather conditions (periods of drought, solar cycles or heavier than normal precipitation), construction in or around either the nuclear plant or the sampling 0location, and addition or deletion of other sources of radioactive materials (such as the 0Chernobyl accident). Some of these factors may be obvious while others are sometimes

unknown. Therefore, how trends are identified will include some judgment by plant personnel.

S 3.0 INTERPRETATION OF RESULTS

Review of all 2013 REMP analysis results was performed to identify changes in environmental levels as a result of station operations. The following section depicts and explains the review of these results. Sample data for 2013 was compared to preoperational and historical data. Over the years of operation, analysis and collection changes have taken

place that do not allow direct comparisons for some data collected from 1984 (preoperational) through 2013. Summary tables containing 2013 information required by Technical

Specification Administrative Control 5.6.2 are located in Appendix B.

0Evaluation for significant trends was performed for radionuclides that are listed as required

within Selected Licensee Commitments 16.11-13. The radionuclides include: H-3, Mn-54,

Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, 1-131, Cs-134, Cs-137, Ba-140 and La-140.

Gross beta analysis results were trended for drinking water and gross beta trending for air

particulates was initiated in 1996. Other radionuclides detected that are the result of plant operation, but not required for reporting, are trended.

A comparison of annual mean concentrations of effluent-based detected radionuclides to 0historical results provided trending bases. Frequency of detection and concentrations related

to SLC reporting levels (Table 2.2-A) were used as criteria for trending conclusions. All 2013 maximum percentages of reporting levels attributed to CNS operation were well below the S 100% action level.

Selected Licensee Commitment section 16.11-13 addresses actions to be taken if radionuclides other than those required are detected in samples collected. The occurrences of these radionuclides are the result of CNS liquid effluents which contained the radionuclides.

During 1984-1986, all net activity results (sample minus background), both positive and negative were included in calculation of sample mean. A change in the EnRad gamma spectroscopy system on September 1, 1987, decreased the number of measurements yielding

detectable low-level activity for indicator and control location samples. It was thought that Sthe method used by the previous system was vulnerable to false-positive results.

S All 2013 sample analysis results were reviewed to detect and identify any significant trends.

Tables and graphs are used throughout this section to display data from effluent-based

radionuclides identified since the system change in late 1987. All negative concentration 5values were replaced with zero for calculation purposes. Any zero concentrations used in tables or graphs represent activity measurements less than detectable levels.

SReview of all 2013 data presented in this section supports the conclusion that there were no 5significant changes in environmental sample radionuclide concentrations of samples collected and analyzed from CNS site and surrounding areas that were attributable to plant operations.

In 2013, 260 radioiodine and particulate samples were analyzed, 208 from four indicator 0 locations and 52 at the control location. Particulate samples were analyzed weekly for gross beta. A quarterly gamma analysis was performed on the quarterly filter composite (by location). S Radioiodine samples received a weekly gamma analysis.

0 Figure 3.1 shows individual sample gross beta results for the indicator location with highest annual mean and the control location samples during 2013. The two sample locations' results are similar in concentration and have varied negligibly since preoperational periods. 0 There were no detectable gamma emitters identified for particulate filters analyzed during S

2013. Table 3.1-A shows the highest indicator annual mean and control location annual mean for gross beta in air particulate.

0 There was no detectable 1-131 in air radioiodine samples analyzed in 2013. Table 3.1-B 0 shows the highest indicator annual mean and control location annual mean for 1-131 since 0 1984 (preoperational period). The table shows similar concentrations for both the indicator and control locations and the activities decreasing from early in the operational history of the 0 plant. No 1-131 activity due to CNS plant operations has been detected since 1987. 0 0

3.2 DRINKING WATER S

0 Gross beta and gamma spectroscopy were performed on 26 drinking water samples. The samples were composited to create 8 quarterly samples that were analyzed for tritium. One 0 indicator location was sampled, along with one control location.

No gamma emitting radionuclides were identified in 2013 drinking water samples. There 0 have been no gamma emitting radionuclides identified in drinking water samples since 1988.

Table 3.2 shows highest annual mean gross beta concentrations for the indicator location and S control location since preoperation. The indicator location (downstream of the plant effluent release point) average concentration was 1.79 pCi/I in 2013 and the control location S concentration was 1.59 pCi/l. The 2012 indicator mean was 1.89 pCi/l. The table shows that 0 current gross beta levels are not statistically different from preoperational concentrations.

0 Tritium was detected in the four indicator samples and in two of the four control samples S during 2013. The mean indicator tritium concentration for 2013 was 622 pCi/1, 3.11% of reporting level. The mean control tritium concentration for 2013 was 664 pCi/1, 3.32% of reporting level. Figure 3.2 and Table 3.2 display the highest indicator and control location annual mean concentrations for tritium since 1984.

S The concentration of tritium in drinking water is affected by releases from the Catawba plant 0 and the McGuire Nuclear Station, located approximately 40 miles upstream of the Catawba plant on the Catawba River.

0 The dose for consumption of water was less than one mrem per year, historically and for 2013; therefore low-level iodine analysis is not required.

A total of 39 monthly surface water samples were analyzed for gamma emitting 0 radionuclides. The samples were composited to create 12 quarterly samples for tritium 0 analysis. Two indicator locations and one control location were sampled. One indicator location (208) is located near the liquid effluent discharge point.

0 All 2013 indicator location samples contained tritium with an average concentration of 4,618 pCi/l. Indicator Location 208 (Discharge Canal) showed a range of activities from 4,490 to 14,800 pCi/I which had the highest mean concentration of 8,615 pCi/l. Tritium was detected 0 in three of the four control samples during 2013 with an average concentration of 402 pCi/l.

0 No gamma emitting radionuclides were identified in 2013 surface water samples. Table 3.3 summarizes the indicator annual means of radionuclides detected since the change in the 0 gamma spectroscopy analysis system in 1987. Visual inspection of the tabular data did not reveal any increasing trends.

II II II 3.10 DIRECT GAMMA RADIATION 3.10.1 ENVIRONMENTAL TLD II In 2013, 164 TLDs were analyzed, 152 at indicator locations and 12 at control locations. TLDs are collected and analyzed quarterly. A transit background for environmental TLDs is determined based on ANSI N545. The highest annual mean exposure for an indicator location was 96.7 milliroentgen. The annual mean exposure for the control locations was 58.0 milliroentgen.

II Figure 3.10 and Table 3.10 show TLD inner ring (site boundary), outerRing (4-5 miles), and control location annual averages in milliroentgen per year.

Preoperational data and rolling ten year operational data averages are also given.

As shown in the graph, inner ring, outer ring, and control data averages historically compare closely. Inner and outer ring averages comprise a number of data points with control averages representing only three locations.

The calculated total body dose (from gaseous effluents) for 2013 was 1.96E0 mrem, which is 2.51% of the average inner ring TLD values. Therefore, it can be concluded that discharges from the plant had very little impact upon the measured TLD values.

0 A TLD intercomparison program is conducted as part of the quality assurance program. Results of this program are included in section 5.10.

3.10.2 ISFSI The Catawba Independent Spent Fuel Storage Installation (ISFSI) is a secured area constructed to provide dry storage for spent nuclear fuel. The principal components of the ISFSI are concrete vertical storage modules that hold stainless steel dry storage canisters containing irradiated fuel assemblies.

S The ISFSI is located approximately 300 meters north of the Unit 2 reactor building. TLD results are evaluated quarterly to identify trends and demonstrate compliance with dose and dose rate limits at the ISFSI boundaries, the Owner Controlled fence north of ISFSI and at the Exclusion Area Boundary in the west sector. Catawba began storage of spent fuel at the ISFSI in 2007.

Doses measured by environmental TLDs show little or no change since the current TLD system was implemented.

0 4.0 EVALUATION OF DOSE

4.1 DOSE FROM ENVIRONMENTAL MEASUREMENTS 0Annual doses to maximum exposed individuals were estimated based on measured

concentrations of radionuclides in 2013 CNS REMP samples. The primary purpose of estimating doses based on sample results is to allow comparison to effluent program dose estimates.

0Doses based on sample results were calculated using the methodology and data

presented in NRC Regulatory Guide 1.109. Measured radionuclide concentrations, averaged over the entire year for a specific radionuclide, indicator location and sample

type, were used to calculate REMP-based doses. Where applicable, average background concentration at the corresponding control location was subtracted. Regulatory Guide 01.109 consumption rates for the maximum exposed individual were used in the

calculations. When the guide listed "NO DATA" as the dose factor for a given radionuclide and organ, a dose factor of zero was assumed.

Maximum dose estimates (Highest Annual Mean Concentration) based on fish sample

results are reported in Table 4.1-A. The individual critical population and pathway dose

calculations are reported in Table 4.1-B.

0REMP-based dose estimates are not reported for airborne radioiodine, airborne 0particulate, milk, or ground water sample types because no radionuclides attributable to

CNS operations were detected. Naturally occurring K-40 and Be-7 were detected in

some samples but were not included in any REMP-based dose estimates. Dose estimates are not reported for surface water because sampled surface water is not 0considered to be a potable drinking water source although surface water tritium 0concentrations are used in calculating doses from fish. Exposure estimates based upon

REMP TLD results are discussed in Section 3.10.

0The maximum environmental organ dose estimate for any single sample type (excluding

TLD results) collected during 2013 was 1.63E-2 mrem to the adult liver, total body,

thyroid, kidney, lung, and GI-LLI from consuming fish.

0 4.2 ESTIMATED DOSE FROM RELEASES

Throughout the year, dose estimates were calculated based on actual 2013 liquid and gaseous effluent release data. Effluent-based dose estimates were calculated using the RETDAS computer program which employs methodology and data presented in NRC Regulatory Guide 1.109. These doses are shown in Table 4.1-A along with the

corresponding REMP-based dose estimates. Summaries of RETDAS dose calculations

are reported in the Annual Radioactive Effluent Release Report (reference 6.6).

6 The effluent-based liquid release doses are summations of the dose contributions from the drinking water, fish, and shoreline pathways. For iodine, particulate, and tritium exposure the effluent-based gaseous release doses are summations of the dose 6 contributors from ground/plane, inhalation, milk and vegetation pathways.

6 4.3 COMPARISON OF DOSES The environmental and effluent dose estimates given in Table 4.1-A agree reasonably well. The similarity of the doses indicate that the radioactivity levels in the environment do not differ significantly from those expected based on effluent measurements and modeling of the environmental exposure pathways. This indicates that effluent program dose estimates are both valid and reasonably conservative.

There are some differences in how effluent and environmental doses are calculated that affect the comparison. Doses calculated from environmental data are conservative because they are based on a mean that includes only samples with a net positive activity versus a mean that includes all sample results (i.e. zero results are not included in the mean). Also, airborne tritium is not measured in environmental samples but is used to calculate effluent doses.

Additionally, in 2010 Catawba began reporting estimated dose from effluent Carbon 14 (C-14). This change came about with the issuing of Regulatory Guide 1.21, Revision 2, Measuring, Evaluating and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste. A description of this change is found in the 2010 Annual Radiological Effluent Release Report. C-14 is not measured in the environment and therefore, environmental and effluent doses from C-14 cannot be compared directly.

In calculations based on liquid release pathways, shoreline sediment, drinking water, and fish were the predominant dose pathways based on environmental and effluent data.

The maximum total organ dose based on 2013 environmental sample results was 1.63E-2 mrem to the adult liver, total body, thyroid, kidney, lung, and GI-LLI. The maximum total organ dose of 1.09E-1 mrem for liquid effluent-based estimates was to child liver.

0 In calculations based on gaseous release pathways, vegetation was the predominant dose pathway for effluent samples. The maximum total organ dose for gaseous effluent estimates was 4.82E0 mrem to the child bone. No radioactivity was detected from gaseous pathways in environmental samples; therefore, there is no calculated dose.

S The doses calculated do not exceed 40CFRI90 or IOCFR50 dose commitment limits for members of the public. Doses to members of the public attributable to the operation of CNS are being maintained well within regulatory limits.

6 ENVIRONMENTAL SAMPLING AND ANALYSIS PROCEDURES Adherence to established procedures for sampling and analysis of all environmental media at Catawba Nuclear Station was required to ensure compliance with Station Selected Licensee Commitments. Analytical procedures were employed to ensure that Selected Licensee Commitments detection capabilities were achieved.

Environmental sampling and analyses were performed by EnRad Laboratories, Dosimetry and Records, Fisheries and Aquatic Ecology.

This appendix describes the environmental sampling frequencies and analysis procedures by media type.

I. CHANGE OF SAMPLING PROCEDURES 0 0

No changes were made to the sampling procedure during 2013.

II. DESCRIPTION OF ANALYSIS PROCEDURES 0 0

Gamma spectroscopy analyses are performed using high purity germanium gamma detectors and Canberra analytical software. Designated sample volumes are transferred to appropriate counting geometries and analyzed by gamma spectroscopy. Perishable samples such as fish and broadleaf vegetation are ground to achieve a homogeneous mixture. Soils and sediments are dried, sifted to remove foreign objects (rocks, clams, glass, etc.) then transferred to appropriate counting geometry.

Low-level iodine analyses are performed by passing a designated sample aliquot through a pre-weighed amount of ion exchange resin to remove and concentrate any iodine in the aqueous sample (milk). The resin is then dried, mixed thoroughly, and a net resin weight determined before being transferred to appropriate counting geometry and analyzed by gamma spectroscopy.

Tritium analyses are performed quarterly by using low-level environmental liquid scintillation analysis technique on a Packard 2550 liquid scintillation system or Perkin-Elmer 2900TR liquid scintillation system. Tritium samples are distilled and batch processed with a laboratory fortified blank, matrix spike, matrix spike duplicate, and blank to verify instrument performance and sample preparation technique are acceptable.

w* Gross beta analysis is performed by concentrating a designated aliquot of sample precipitate and analyzing by Tennelec XLB Series 5 gas-flow proportional counters.

0Samples are batch processed with a blank to ensure sample contamination has not

occurred.

III. CHANGE OF ANALYSIS PROCEDURES SQuarterly gamma spectroscopy analysis of airborne particulate filter composite (by

location) was implemented during 2013; elective weekly gamma spectroscopy of the

airborne particulate individual filter was discontinued.

0 IV. SAMPLING AND ANALYSIS PROCEDURES A.1 AIRBORNE PARTICULATE AND RADIOIODINE 0

Airborne particulate and radioiodine samples at each of five locations were composited continuously by means of continuous air samplers. Air particulates

were collected on a particulate filter and radioiodines were collected in a

charcoal cartridge positioned behind the filter in the sampler. The samplers are

designed to operate at a constant flow rate (in order to compensate for any filter loading) and are set to sample approximately 2 cubic feet per minute. Filters and cartridges were collected weekly. A separate weekly gamma analysis was

performed on each charcoal cartridge. A weekly gross beta analysis was

performed on each filter. A quarterly gamma analysis was performed on the

quarterly filter composite (by location). The continuous composite samples were collected from the locations listed below.

A.10 DIRECT GAMMA RADIATION (TLD)

Thermoluminescent dosimeters (TLD) were collected quarterly at forty-one

locations. A gamma exposure rate was determined for each TLD. TLD locations

are listed in Table 2.1-B. The TLDs were placed as indicated below.

An inner ring of 16 TLDs, one in each meteorological sector in the 0*general area of the site boundary.

An outer ring of 16 TLDs, one in each meteorological sector in the 6 to 8 kilometer range.

S* The remaining TLDs were placed in special interest areas such as population centers, residential areas, schools, and at three

control locations.

A.11 ANNUAL LAND USE CENSUS 0

An Annual Land Use Census was conducted to identify within a distance of 8 kilometers (5.0 miles) from the station, the nearest location from the site boundary in each of the sixteen meteorological sectors, the following:

V. GLOBAL POSITIONING SYSTEM (GPS) ANALYSIS 6 0

The Catawba site centerline used for GPS measurements was referenced from the Catawba Nuclear Station Updated Final Safety Analysis Report (UFSAR), section 6 2.1.1.1, Specification of Location. Waypoint coordinates used for CNS GPS 6 measurements were latitude 35°-3'-5"N and longitude 81'-4'-10"W. Maps and 0 tables were generated using North American Datum (NAD) 27. Data normally reflect accuracy to within 2 to 5 meters from point of measurement. All GPS field 0

measurements were taken as close as possible to the item of interest. Distances for 0 the locations are displayed using three significant figures. 0 0

1. The Lower Limit of Detection (LLD) is the smallest concentration of radioactive material in a sample that will yield a net count above system background which will be detected with 95 percent probability and with II only 5 percent probability of falsely concluding that a blank observation represents a "real" signal. Due to II counting statistics and varying volumes, occasionally lower LLDs are achieved. Refer to Section 2.3.2 for II an explanation of how LLD values were derived. II 6I

2. Mean and range are based on detectable measurements only.

0I

3. The fractions of all samples with detectable activities at specific locations are indicated in parentheses. 0I 0I

4. Missing samples or surveillances are discussed in Appendix C or Appendix D.

5. TLD exposure is reported in milliroentgen (mR) per standard quarter (91 days).
