1.0 INTRODUCTION

SC&A was tasked by the Advisory Board on Radiation and Worker Health to conduct a review of 

bioassay data completeness for construction trade workers (CTWs) at SRS, resulting in their report 

Evaluation of Savannah River Site Subcontractor Bioassay Data Completeness (SC&A 2017). The 

National Institute for Occupational Health and Safety (NIOSH) then issued its Response to SC&A’s 

Evaluation of SRS Subcontractor Bioassay Data Completeness (NIOSH 2018). The SC&A report and 

the response cover the period from 1989 to 1998. This report is an extension of that response to 

cover the years between 1972 and 1997.

A sample set of 886 sCTWs was selected from the 6,097 individuals in NOCTS as of August 2018

who have a claim after working at SRS.

Each worker’s records were researched to determine if the individual worker was monitored using 

WBCs, tritium bioassay by urine samples, non-tritium bioassay by urine samples, and external 

exposure monitoring by thermoluminescent detectors (TLDs). For each year the worker was 

employed at SRS, the monitoring records were reviewed to determine if they included external 

monitoring results, whole-body counts (WBCs), urine bioassay for tritium, and/or urine bioassay for all 

other radionuclides. Totals of each category were divided by the number of workers employed in that 

year to calculate the fraction for that category. For example, in 1972 there were 83 sCTWs employed 

and 68 of those or 82% were found to have external monitoring records. 

The monitoring records were provided by SRS in response to claim requests and were stored in 

NOCTS claim documents. The NOCTS database includes employment ranges, which were also 

confirmed during the review of the records provided by SRS.

For each worker, each year they were employed was recorded. For WBCs, tritium bioassay by urine 

samples, non-tritium bioassay by urine samples, and external exposure results, the year was 

recorded if there were one or more monitoring records in that year. For some, the monitoring was in 

the years following employment. Monitoring data in the years prior to employment was assumed to 

be baseline monitoring and was not used.

2.0 PURPOSE

This report provides estimates of the numbers and fractions of sCTWs who were monitored by SRS 

for external and internal exposure during 1972 through 1997. These estimates were established from 

the number of claims in the NOCTS database in which one or more position descriptions met the 

definition of a CTW and then through a manual review of SRS dosimetry documents in which those 

claimants had records of external monitoring, WBC, and urine bioassay results within each year.

3.0 BIOASSAY SAMPLING PROGRAM

SRS implemented bioassay programs to cover 35 facilities that processed actinides, fission products, 

activation products, and tritium (WSRC 1993). During the years 1972 through 1997, SRS performed 

in vivo and in vitro sampling for radioactive material using both routine and special sampling.

3.1 ROUTINE BIOASSAY PROGRAM

The bioassay program was part of an overall strategy described as “Defense in Depth” and included 

the zero-intake policy, engineered and procedural controls, personal protective equipment, and 

surveillance. This surveillance included air monitoring, facility and personnel contamination surveys, 

and the routine bioassay program (ORAUT 2017a).
Document No. ORAUT-RPRT-0094 Revision No. 00 Effective Date: 09/13/2019 Page 7 of 66

Under the Routine Bioassay Program, workers supplied urine samples and underwent whole-body 

and chest counts on a prescheduled, routine basis. Workers also supplied routine samples as 

requested when necessitated by working under Radiological Work Permits with bioassay 

requirements. Details on the analysis techniques and their detection efficiencies are available in 

ORAUT-TKBS-0003, Savannah River Site (ORAUT 2005).

A worker’s enrollment in the Routine Bioassay Program was based on the radioactive hazards 

associated with the facility where the individual worked and the type of work the worker normally 

performed. Enrollment in the program was defined by building or specific operation and by the task, 

such as operators, laboratory personnel, supervisory personnel, etc.

The Routine Bioassay Program was not used at SRS to detect and assess the intake of radionuclides. 

It was a “final quality control check that exposure control measures and workplace monitoring 

programs worked” (ORAUT 2017b).

3.2 SPECIAL BIOASSAY PROGRAM

SRS designed its Special Bioassay Sampling Program to assess “inadvertent intakes” of radioactive 

material. Under this program, samples were required in response to unusual or unanticipated 

circumstances such as being involved in a contamination incident or from air sampling results.

All bioassay monitoring data obtained by SRS for the worker are requested in the claim process. 

These monitoring results do not indicate which were obtained under the Routine Bioassay Program or 

the Special Bioassay Program. However, a review of a dataset obtained by NIOSH from SRS that 

included all bioassay results for all workers and covered the years between 1991 and 2000 found that 

less than 5% of the samples were flagged as special bioassay samples. The greatest majority of the 

bioassay results provided by SRS for claimants were collected under the Routine Bioassay Program.

4.0 SUBCONTRACTOR CONSTRUCTION TRADE WORKERS

CTWs at SRS, also referred to as building trades workers, fit into two categories. The first consists of 

workers hired by the site prime contractor mostly in permanent employment, while the second 

consists of workers brought in temporarily and often for short periods to perform specific tasks. Many 

of the workers in the second category have repeat temporary employment at either SRS or other U.S. 

Department of Energy (DOE) sites. From the onset of construction at SRS workers in the first 

category were employed by DuPont or Westinghouse Savanah River Company (WSRC) while 

workers in the second category were employed by subcontractors such as B.F. Shaw Company, 

Miller-Dunn Electric Company, and North Brothers Company. In 1989, Bechtel Savannah River took 

over construction duties at SRS. Bechtel tended to use CTWs hired through subcontracted 

companies (ORAUT 2019).

4.1 DETERMINATION OF SUBCONTRACTED CONSTRUCTION TRADE WORKER STATUS

The NOCTS database includes claimant data such as name, social security number, position title, and 

the dates when they worked at the site. Employment start and end dates are kept in the database 

and in many cases include more than one period of work. The NOCTS database keeps one or more 

pairs of these dates for each claimant. The “position title” is populated by information supplied by the 

worker or by their survivor. There is only one “position title” for each claimant for each period worked 

and in many cases these included more than one job description. .

The NOCTS database also includes scanned copies of the documents from SRS and the U.S. 

Department of Labor (DOL) in response to claim requests. Documents in NOCTS include in most 
Document No. ORAUT-RPRT-0094 Revision No. 00 Effective Date: 09/13/2019 Page 8 of 66

 

cases references to the company that employed the worker or information that can be used to indicate 

if the worker was working for the prime contractor or for a subcontractor. 

The full set of SRS claimants in the NOCTS database was reviewed to select those claimants who 

worked at the site for any amount of time between January 1, 1972, and December 31, 1997. As of 

August 2018, there were 6,097 such individuals. Note that in this report, the term “claimant” is used 

for the worker associated with the claim, not necessarily the person who initiated the claim. The 

person who initiated the claim and provided information about the worker, including their position, was

in many cases a surviving spouse or child of the worker. 

The position title field was used to select only those whose position title contained one or more of the 

CTW trades in ORAUT-OTIB-0081, Internal Coworker Dosimetry Data for the Savannah River Site 

(ORAUT 2019). This initial set of job types used to filter the claimants is in Table 4-1. Additional 

equivalent titles were added to this list such as journeyman, apprentice, truck driver, sheetmetal 

worker, and steel worker. The position titles were manually reviewed to select those workers where 

the position title contained alternate spellings, such as “iron worker” and “ironworker”.

In most cases, position titles covered many years and included multiple positions. The initial list was 

reduced by removing all claimants whose position titles included other positions, such as “operator,” 

“engineer,” or “procurement.” A partial list of other position titles in NOCTS is shown in Table 4-2. In 

addition, position titles were reviewed for words that indicated management. The list was reduced by 

removing all workers whose position titles included “supervisor,” “manager,” and similar terms. If the 

position title included multiple crafts, such as “electrician/sheet metal worker/welder,” that claimant 

was included in the list. If the position title included construction trade positions and nonconstruction 

trade positions such as “welder/HP” that claimant was not included. If the claimant changed jobs 

between 1972 and 1997 to one that did not meet these strictures, they were removed from the list. A 

total of 33 were removed who initially net the criteria but were found to have later job titles such as 

foreman or supervisor or to have changed to non-CTW occupations.

The list was compared to previously generated lists of workers that identified their types of 

employment. The list was reduced by removal of all workers who were previously identified to not be 

subcontractors.

The NOCTS documents were reviewed for each of the remaining claimants in the list. Previous 

research for ORAUT-OTIB-0081 identified that the payroll identification number (PRID) included a 

prefix code that indicated the worker’s employment status, and in some cases the craft. If the initial 

number in a PRID was a “2” for example, it indicated employment by the prime contractor. Numbers 

equal to or greater than “4” indicated that the worker was a subcontractor (ORAUT 2019). During the 

inspection of each worker’s NOCTS files, if the PRID indicated work for the prime contractor, or if the 

documents listed the employer as the prime contractor, that worker was removed from the review list.

Determination of sCTW status was based on multiple document reviews. The PRID can be 

determined from the observation of (1) the employee number as four or five digits and the Roll 

number (denoted as “rl” on the external dosimetry monthly or quarterly reports), (2) Roll 2 for prime 

contractor CTW, Roll 4, 5, or 6 for sCTW, and (3) the prefix or craft code as described in Table 4-3. 

Note that the crafts in Table 4-1 were used to select the sCTW claimants and the craft codes in Table 

4-3 were used to interpret their monitoring records.

The standard way to determine a CTW is by use of the criterion as stated in ORAUT-OTIB-0081 as 

defined on the website for the DOE-funded Building Trades National Screening Program (ORAUT 

2019, p. 33).

After all reviews, a final list of 886 sCTW claimants remained. Figure 4-1 below is a pie chart of the 

position titles that remained in the final list. This is an approximation because many position titles

included more than one craft. For those, the first craft listed was used. For example, if the position 

title was “welder/pipefitter” the worker was counted as a “welder” in this pie chart. Similar position 

titles such as “laborer” and “construction worker” were also combined in this chart. Electricians and 

pipefitters make up almost half of the sCTW list. All individual position titles are shown in the list of 

sCTWs in Table B-1. These are the initial position titles and do not include all job periods. The 
Document No. ORAUT-RPRT-0094 Revision No. 00 Effective Date: 09/13/2019 Page 10 of 66

 

position titles for those who changed jobs before 1997 were reviewed to assure they met the definition 

of CTW.

Figure 4-1. sCTW position titles.

These 886 claimants in the sCTW list were researched in NOCTS for their employment dates, the 

years they were monitored by WBCs and the years they were monitored by urine bioassay. The urine 

bioassay was counted in two categories, records of tritium results and records of any other nuclide 

results. For the external monitoring, WBC, tritium urine bioassay, and non-tritium urine bioassay, the 

year was flagged for any result within the year. For example, for each year the sCTW was employed 

if there were one or more tritium results within the year then that year was counted for that sCTW. All 

monitoring data obtained from the NOCTS records review and used in this report is provided in 

Attachment B as Table B-1.

4.2 CLAIMS TRACKING SYSTEM RECORDS

The analysis examined SRS dosimetry forms and database summary outputs from 1972 through 

1997 for this report. Attachment A shows examples of reports of urine bioassay results, WBC results, 

chest counts, and TLD results. 

4.2.1 Determination of the Employee Identification

From 1972 to 1987 the PRID numbers were present on the external dosimetry forms, but after 1989 

Social Security Numbers were used on these forms for worker identification. For examples of the roll 

number and prefix or craft code, see Figure A-6 in Attachment A. Other data such as the date, 

primary work area, cycles, or quarter monitoring periods are also present on these forms. If the PRID 

number at any time during their employment indicated employment by the prime contractor, the 

worker was removed from the list.
Document No. ORAUT-RPRT-0094 Revision No. 00 Effective Date: 09/13/2019 Page 11 of 66

4.2.2 Determination of the Employment Period

Employment date ranges are maintained in the NOCTS database. These were confirmed by review 

of claimant forms. The employment period can be found in the DOL initial report (Figure A-1) and in 

the cover letter provided by SRS in their dosimetry document. If these forms at any time during their 

employment indicated employment by the prime contractor, the worker was removed from the list.

4.2.3 External Dose Records

The Health Protection Radiation Exposure Database (HPRED) database was used by SRS starting in 

the 1990s to manage worker exposure data. Reports from the HPRED were used for 1991 and later 

years (Figure A-2). 

An overall summary form (Figure A-3) and quarterly summary forms (Figure A-4) indicated the dates 

that external dosimetry was performed. The individual exposure records were listed in monthly or 

quarterly reports that varied during different years (Figures A-5 through A-9). 

4.2.4 Urine Bioassay Records

The HPRED output form (Figure A-2) was found to contain tritium bioassay results listed by 

concentration along with external monitoring data.

Urine bioassay results for nuclides other than tritium were listed in a Non-tritium Bioassay Results 

report (Figure A-10) in the years 1972 and later.

Handwritten Employee Bioassay Cards (Figure A-11) were used in earlier years and can contain both 

tritium and non-tritium results. Acronyms used on these cards include: T = tritium, EU= enriched 

uranium, U = Uranium, Pu = plutonium, FPIA = fission products induced activity.

Tritium results were also found in summary reports used between 1986 and 1992 (Figure A-12).

The In Vitro Individual Monitoring report form (Figure A-13) contained both tritium and non-tritium

results.

4.2.5 Whole-Body Count Records

The WBC reports varied in different years but always indicated the worker, dates, nuclides detected, 

including naturally occurring 40K, along with the results (Figures A-14 through A-17). For some 

periods the employer was listed (See Figure A-16).

5.0 EVALUATION OF CLAIMS TRACKING SYSTEM DATA

The data SRS provided in response to a claimant request include the type of monitoring, the analytical 

results, and the dates the monitoring was performed. The documents do not include specific 

information on the locations or areas that person worked while at SRS. The graphs and percentages 

in this report provide a broad description of the fraction of sCTW workers who were monitored in a 

given year but do not indicate which, if any, of the workers might have been exposed and which, if 

any, would have been required under DOE orders to have bioassay monitoring.

SRS workers supplied urine samples and submitted to chest scans and WBCs on a prescheduled 

routine basis to be analyzed for tritium, plutonium, strontium, neptunium, uranium, EU, americium, 

curium, californium, and fission products / induced activity. Routine monitoring for tritium was as often 

as weekly, while monitoring for plutonium, strontium, neptunium, uranium, EU, americium, curium, 
Document No. ORAUT-RPRT-0094 Revision No. 00 Effective Date: 09/13/2019 Page 12 of 66

 

californium, and fission products / induced activity was typically annually or in some instances as 

infrequent as once every three years. 

5.1 TABLE OF SUBCONTRACTED CONSTRUCTION TRADE WORKER CLAIMANTS

Table B-1 in Attachment B lists results for the 886 sCTW claimants from the review of SRS-supplied 

dosimetry records in NOCTS. The table is sorted by the first year employed and then alphabetically 

by craft. Where the contractor was not identified and the claimant remained in the list due to the Roll 

number in the PRID, the contractor is listed as “Const” indicating the Construction Division.

The table is coded for sCTWs with external monitoring, WBC, tritium, and non-tritium results for each 

year of employment as shown in the legend preceding the table in Attachment B. Some sCTW had 

monitoring data in years following the years they were employed with the majority of those being 

whole body scans. 

An overall trend apparent in this Table B-1 is that sCTWs who have monitoring do not have internal 

monitoring records or do not have external monitoring records for the first year of employment. One 

hundred and fifty seven sCTW began their employment before 1972. For all 729 sCTWs who started 

employment between 1972 and 1997, 279 had internal monitoring records in their first year of 

employment and 353 had external monitoring records in their first year of employment. Most of these 

had monitoring records later in their employment. For all sCTW, 774 or 87% had internal records and 

783 or 88% had external records. Only 67 of the total 886 sCTW claimants or 7.6% were found to 

have no monitoring records between 1972 and 1997 for either external or internal monitoring. Of 

those, 35 worked at SRS for less than 1 year. 

The lack of internal monitoring records in the initial year of employment is partially due to the fact that 

internal monitoring was performed after the work in radiologically controlled areas. The routine 

bioassay frequencies for non-tritium urine and for WBC was annually or, in some cases for plutonium 

bioassay, longer. For routine sampling this would in many cases result in a sample more than a year 

after the work. Note, however, that any indication of internal uptakes such as a loss of containment or 

contamination found on a worker would have triggered the Special Bioassay Program and immediate 

sampling. 

In Table B-1 is a column addressing whether the worker had internal monitoring within the last year 

they had external monitoring. SRS policies required the assignment of external dosimeters for all 

workers before entry of radiologically controlled areas (ORAUT 2005). Of all 886 sCTW, 274 worked 

at SRS after 1997 and only 612 had their last year of employment at SRS between 1972 and 1997. 

Of these, 474 or 77% had internal monitoring records during or after the last year they had external 

monitoring records.

5.2 NUMBERS OF WORKERS

Table 5-1 lists the numbers of all SRS workers with claims who were employed each year between 

1972 and 1997 and the numbers of those sCTWs who were employed in those years. The numbers 

of all SRS workers with claims and sCTW with claims are shown in Figure 5-1. Both show similar 

growth and decline during these years. As the claimants are taken to be a representative sampling of 

the population of workers, the increases between 1972 and 1990 and the decline between 1990 and 

1997 are taken to represent the overall increase and decrease of the site population during this time. 

Note that the population of the sCTWs relative to the total number of claimants was not constant 

during these years. The number of sCTWs are 4% of the total SRS claimants in 1972, increasing to a 

maximum of 18% in 1986, and then decreasing to 9% by 1997. To compensate for these changes, all 

calculations were made relative to the number of sCTW employed in that year. For example, to

5.3 INTERNAL AND EXTERNAL MONITORING

Not all sCTWs were found to have had external monitoring records. The fractions of those with 

records in each year are listed in Table 5-2 and plotted in Figure 5-2. The fraction with external 

monitoring ranged between 62% in 1984 and 96% in 1991. 

SRS practices required external dosimetry for workers entering areas controlled for exposure to 

radiation (ORAUT 2005). It is assumed that the population without any external monitoring were 

unlikely to have worked in areas that would have provided significant internal exposures. Note that 

external monitoring requirements were applied before work activities by issuing a TLD badge, and 

internal monitoring requirements were applied afterwards in the form of a urine bioassay sample or a 

WBC. Fractions of sCTW with monitoring records are calculated for all sCTW, listed in Table 5-2, and 

for only those sCTW with external monitoring records, listed in Table 5-3.

Figure 5-3 shows the fractions of sCTW claimants with internal monitoring records.

Requirements for routine bioassay were based on the areas and buildings the worker had entered. 

The requirements for special bioassay remained constant during the 1970s through the 1990s; special 

bioassay sampling was required for events suspected to have provided an increased risk of internal

exposure, such as a contamination event or a failure of protective measures. A discussion of the 

distinction between routine and special bioassay for sCTW at SRS between 1989 and 1998 can be 

found in NIOSH (2018).

SRS policies required the assignment of external dosimeters for all workers before entry of

radiologically controlled areas (ORAUT 2005). Workers who would have been expected to work with 

materials with a potential for internal exposure would have already been issued TLDs.

Assuming that some sCTWs were not issued TLDs because their work did not require entry into 

radiologically controlled areas, the fractions with internal monitoring records were calculated for only 

those sCTW with external monitoring records within that year. These fractions, listed in Table 5-3, 

ranged from 28% in 1978 to 98% in 1993. 

The fractions of externally monitored sCTWs with internal monitoring in Table 5-3 are higher than the 

fractions of all sCTWs with internal monitoring records in Table 5-2. These results provide better 

estimates of the potentially exposed sCTWs that were monitored. 

5.4 WHOLE-BODY COUNTS, TRITIUM BIOASSAY, AND NON-TRITIUM BIOASSAY

The internal monitoring records were divided into three categories: WBCs, urine bioassay for tritium, 

and all other urine bioassay. Where the records included chest counts, for all cases reviewed they 

were concurrent with a WBC. 

Calculating these fractions for only those workers with external monitoring records resulted in higher 

fractions for most years (Table 5-3). However, the changes were smaller than the overall trends and 

did not change these trends substantially. 

At SRS, areas where tritium provided more than 10% of an expected exposure were limited to the 

reactors and tritium processing areas (Farrell and Findley 1999). WBC and chest counts do not 

detect tritium and are used to monitor intake of actinides, fission products, and activation products. 
Document No. ORAUT-RPRT-0094 Revision No. 00 Effective Date: 09/13/2019 Page 17 of 66

 

Grouping WBC and non-tritium bioassay data to estimate the fraction monitored is appropriate 

because workers in areas with non-tritium radionuclides may have been monitored by either method. 

The fractions of sCTWs with either non-tritium or WBC within three years of the year employed 

divided by the numbers of sCTW with external monitoring within the year employed are presented in 

Table 5-4 and plotted in Figure 5-4. These fractions are significantly higher than those fractions of 

sCTWs with WBC or non-tritium bioassay within the same year. These fractions exceed 70% for

1979 through 1995 and exceed 90% for 1987 through 1995.

6.0 CONCLUSIONS

External monitoring records showed that the sCTW had been issued TLDs, a requirement prior to 

work in radiologically controlled areas. Although not all sCTW were found to have internal monitoring 

records for each year of employment at SRS, for the years after 1979, 63% or more of externally 

monitored sCTW had internal monitoring records. The lowest fraction of externally monitored sCTW 

with internal records was 28% in 1978. For the subset of internal monitoring records related to other 

radionuclides with longer biological residence times and longer monitoring periods than tritium, the 

fractions of externally monitored sCTW with either WBC of non-Tritium records are 52% or greater for 

the years after 1979 with the lowest fraction of 5% in 1977 and 1978.

Figure 5-4. Externally monitored sCTWs, fractions monitored by WBC or 

nontritium bioassay. 

All calculations were based on the numbers of workers with monitoring records in NOCTS. NOCTS 

records do not indicate which workers entered into radiologically controlled areas or had the potential 

for internal exposure.

An upper estimate of the sCTW who had the potential for internal exposure may be based on those 

sCTW with external monitoring records. 

A review of the monitoring records from SRS for all sCTW claimants identified to have worked at the 

site between the years 1972 and 1997 found that the number of employed sCTWs increased and 

decreased similarly to the overall number of SRS workers. 

These fractions are conservative estimates of the fractions of exposed workers that were monitored 

as not all sCTWs worked with radioactive materials, not all sCTWs who worked in radiologically 

controlled areas were internally exposed, and routine bioassay for non-tritium nuclides was not 

required within the same year as the exposure.

6.1 IMPACT TO DOSE RECONSTRUCTION

Dose is reconstructed for SRS workers by using either the monitoring results provided SRS or by 

using the coworker model based on those results. The monitoring results include those from special 

bioassay sampling which occurred whenever there was any suspected intake of radionuclides and 

from the routine bioassay sampling which was in place to confirm controls were working to prevent 

intakes. The greatest number of results were obtained from routine samples from the bulk of the SRS 

worker population. Dose reconstruction based on SRS monitoring records includes all monitoring 

data, including records of monitoring beyond employment dates.

Extended gaps in bioassay monitoring that precede bioassay results do not significantly affect the 

ability to perform dose reconstruction for certain SRS radionuclides, such as plutonium, due to the 

long biological retention times. Urine bioassay results obtained years after a plutonium uptake can be 

used to provide useful dose estimates. Using a three year span between the time of potential 

exposure and the time of the bioassay for non-tritium radionuclides significantly increases the fraction

of monitored sCTW, as shown in Figure 5-4. The fraction of monitored sCTW would increase for each 

year the span between employment and bioassay was increased.

6.2 DATA TRENDS

There are several clear trends in the data.

• Most sCTW had external monitoring records. Between 62% and 96% of the sCTW were found 

to have external monitoring records within the same year as employment.

• For externally monitored sCTW, a requirement prior to entry in radiologically controlled areas, 

the annual fractions of those with internal monitoring records ranged between 28% and 98%. 

The lowest fractions were in the latter 1970’s and generally increased over time. Between 

1972 and 1979 the average of the fractions is 51%, for the 1980’s it is 72%, and for 1990 

through 1997 it is 92%. 

• The fraction of sCTWs who were monitored by WBC increased significantly in 1987 and 

remained at or above 70% for most of the 1990s.

• The fraction of sCTWs who were monitored by urine bioassay for tritium neither increased or 

decreased significantly, generally about 20% with the exceptions of the periods 1981 to 1984 

when it approached 40% and 1990 to 1993 when it remained between 40% and 50%. 

• For 1977, 1978, and 1979 the fractions of sCTW with external monitoring and with monitoring

for non-tritium urine bioassay were significantly smaller, 4%, 5%, and 8%, respectively, than in 

the previous and following years. For the years between 1980 and 1997, the fractions did not 

significantly increase or decrease with smaller fractions in 1989 to 1990 and higher fractions in 

1991to 1992.

• Many sCTW did not have monitoring records during their first year of employment. One 

hundred and fifty seven sCTW began their employment before 1972. Of the 729 sCTW who 

started employment between 1972 and 1997, 450 or 62% did not have internal monitoring 

records and 376 or 52% did not have external monitoring records during their first year. For all 

sCTW, 87% had internal monitoring records and 88% had external monitoring records. Note 

that baseline internal monitoring for new employees was included in these data. 

• Only 67 were found to have no internal or external records during their employment between 

1972 and 1997. The remaining 819 of the total 886 sCTW or 92% had external or internal 

monitoring records during their employment. 

The overall trend observed in these data is that the subcontractor construction trade workers who 

were monitored were represented as least as well as other SRS workers. The completeness of the 

data is more than adequate for dose reconstruction and for the basis of the SRS coworker model.

The following table includes a row for each sCTW with cells shaded for each year the worker was employed with one or more of the above 

indicators when monitoring records were found. The letter indicators and shaded cells describe all of the data found in the NOCTS records 

review and used for the tables and graphs in this report.

For example, if only tritium records were found, the indicator is T. But, if both tritium and non-tritium records were found for the sCTW

worker in the same year, the indicator is NT. If external monitoring records, non-tritium records, and whole body count records were found, 

the indicator is ENW. If neither external monitoring records nor internal monitoring records were found in a year the worker was employed, 

the cell is shaded and contains no letter indicators. For some workers, monitoring data was found beyond the dates of employment. 

These are shown in the table in non-shaded cells.

The table also includes a column “Internal Monitoring Evaluation” with a statement of whether the worker was monitored internally by urine

bioassay or WBC during their last year of external monitoring. The choices in this column are “NA - Employment after 1997,” “NA - No 

External Monitoring,” “No - External after Last Internal Monitoring,” “No - External but No Internal Monitoring,” “Yes - Internal after Last 

External Monitoring,” or “Yes - Internal in Last Year of External Monitoring.” There are a total of 612 sCTW with “Yes”, 138 with “No”, and 

274 with “NA”.
