1.0 INTRODUCTION

1.1 PURPOSE

In Draft White Paper, Review of Some SRS Claimant Cases to Examine Badge and Area Codes for 

Adequacy in Thorium SEC Implementation, S. Cohen & Associates (SC&A 2011) reported a review of 

10 claimant cases to identify potential issues that might affect the implementation of the proposed 

Special Exposure Cohort (SEC) class at the Savannah River Site (SRS) (NIOSH 2011). SC&A 

considered the completeness of data available for review and the usefulness of that data in identifying 

work locations. The 10 cases (Table 1-1) were provided by the petitioner or claimant representatives 

and do not represent a random sample.

10 1961–1964

For these 10 cases, SC&A reviewed dosimeter badge data and dosimetry cards from the claimants’ 

U.S. Department of Energy (DOE) files for January 1953 through September 1972 and the computerassisted telephone interview (CATI) responses for each of the claimants. From their review, SC&A 

identified gaps in the available external dosimeter data in the claimant records by yearly quarter. 

SC&A also reported illegible and indeterminate records of work location. SC&A did not provide 

explanation or justification for the cases it reported to have gaps or to be incomplete.

SC&A described their analysis as preliminary without follow-up on the data gaps to determine if the 

gaps could be explained or justified. The Oak Ridge Associated Universities (ORAU) Team for the 

National Institute for Occupational Safety and Health (NIOSH) Dose Reconstruction Project analyzed 

each of the reported gaps, illegible results, and incomplete results to determine if each could be 

explained or justified. The results of that analysis are provided in this report.

2.0 METHOD OF ANALYSIS

The ORAU Team reviewed each instance of a gap, illegible, or incomplete data for each case (see 

Table 2-1). In this analysis, the Team made use, when available, of the DOE-supplied external 

monitoring and bioassay data for each claimant, the CATI data in the NIOSH-Office of Compensation 

and Analysis (OCAS) Claims Tracking System (NOCTS), SRS visitor cards, SRS quarterly dosimetry 

reports in the Site Research Database (SRDB), and SRS work history files. Where sources are not 

cited in this document, information in NOCTS was used. The Team assessed (1) whether monitoring 

data for a gap or an illegible or incomplete record are available in the SRDB, (2) whether gaps could 

be verified or resolved through comparison with bioassay data, or (3) if there is evidence or an 

indication of why a worker was not monitored in a particular period. This analysis sought to address

the reported issues for the 10 cases only; results are not statistically valid for all SRS workers for the 

analyzed period (i.e., 1953 to 1972).

3.0 CASE FINDINGS

The ORAU Team findings for each reported gap in SC&A (2011) are provided in the following 

discussion. Findings are also summarized in Attachment A.

3.1 CASE 1

The gaps for Case 1 were that (1) there were no dosimeter results for 1953 through May 1954 when 

the worker was hired as an operator and (2) there were illegible (assigned) Health Physics (HP) area 

codes on the dosimeter cards for 1954, 1955, 1956, and 1957.

The Team searched for but did not find visitor dosimeter card records in the SRDB for any dosimeter 

assignments for the Case 1 worker. The Team examined the dosimeter cards from the U.S. 

Department of Labor for 1954, 1955, 1956, and 1957. The location code for 1954 is readable as L; a 

bioassay card for 1954 indicates that the Case 1 worker was assigned to L. The scanned copies of 

1955, 1956, and 1957 cards are somewhat illegible. However, the HP area codes (HP area) would be 

readable on microfiche of the card from DOE. DOE-provided bioassay cards show that the Case 1 

worker was assigned to 100P in 1955, 1956, and 1957. The Case 1 worker continued to work at SRS 

until April 17, 1964; no gaps were reported after 1957. The Team confirms a single gap for Case 1

from 1953 through May 1954. While it is possible the Case 1 worker did not work in areas with 

potential for radioactive exposure or, if so, the worker was monitored, the Team can determine only 

that dosimeter data and area codes have either not been reported, or have not been found, for 1953 

through May 1954. Note that thorium was not introduced to Building 773A until July 1953 (NIOSH 

2011).

In the CATI, the claimant’s survivor did not mention Building 773A or CMX/TNX as work locations for 

the Case 1 worker.
Document No. ORAUT-RPRT-0066 Revision No. 00 Effective Date: 09/19/2014 Page 8 of 23

3.2 CASE 2

The reported gaps for Case 2 were (1) missing dosimeter card and area code data for the second 

quarter 1953, (2) illegible area codes in 1954 and 1955, and (3) missing dosimeter card and area 

code data for all quarters of 1958, the second quarter of 1962, all quarters of 1966, the second and 

fourth quarters of 1970, the first quarter of 1971, and the third quarter of 1972. In addition, the code 

000 was listed for HP area code for the second, third, and fourth quarters of 1963, all quarters of 1964 

and 1965, and the first quarter of 1968.

Visitor cards available to the Team begin in 1954. Therefore, the Team confirms a gap for the second 

quarter of 1953. The Team notes that the Case 2 worker has a qualifying area code for the proposed 

SEC class (NIOSH 2011) on more than one of the 1953 cards.

No bioassay card was provided for 1954, but the area code would be readable on microfiche of the 

card available at DOE. The Team examined the 1955 cards; the area code is G2.

No dosimeter assignment records were found for the Case 2 worker by SC&A for the first, third, and 

fourth quarters of 1958. The Team searched for but did not find dosimeter assignment or results 

records for these quarters in the quarterly dosimetry reports in the SRDB. The Team researched the 

worker’s job history and found that the job accounting number prefix changed from G to GI in April 

1958. The worker stayed on the GI prefix until October 1961. The prefix was again changed to GI in 

August 1962. There is a dosimeter assignment for the second quarter of 1958. Further, SRS 

reported the worker’s total dose for 1958 to be 0 mrem. This indicates SRS considered the second 

quarter result to be the only period of monitoring [data from Health Protection Annual Radiation 

Exposure History (HPAREH) database]. NIOSH reported the following for 1958 forward (NIOSH 

2008):

...based on the availability of SRS documentation, and NIOSH’s review of the 

hardcopy records in comparison to the HPAREH database, there does not appear to 

be any significant administrative practice or data issue that would affect the integrity of 

the recorded SRS doses. The results of NIOSH's evaluation on this matter 

demonstrate that the use of HPAREH data is bounding for construction worker external 

photon doses.

By January 1956, SRS Radiation and Contamination Control procedure DPSOP 40 had the following 

requirement: “Film badge dosimeters are to be worn by all personnel entering regulated areas”

(DuPont 1956). The external dosimetry assignments and results available in the SRDB and the 

claimant record represent a complete record for the worker. While the Team cannot say what the GI

prefix means, the prefix does appear to have been assigned to workers that had periods when 

monitoring was not required. The worker’s external dose data is considered complete for 1958 per 

the SRS data. However, for dose reconstruction purposes and in order to be claimant favorable, 

missed doses are assigned independent of this analysis on reported gaps.

SC&A reported a gap in dosimeter assignment for the second quarter of 1962. The Team examined 

the SRS quarterly dosimeter results for the second quarter of 1962 and found the assignment 

(DuPont 1962, p. 27). For all quarters of 1963, 1964, and 1965, SC&A reported the Case 2 worker’s 

HP area code was 000. The Team confirmed those assignments. However, the HP area code of 000

was added to the proposed class description by NIOSH after SC&A performed the cases review. 

Therefore, the issues for 1963, 1964, 1965 are resolved; there are now no gaps or incomplete 

records. SC&A also reported 000 HP area code assignments for the first quarter of 1968; this 

assignment is resolved for the above reason. SC&A reported gaps for all four quarters of 1966. The 

Team found assignments for all four quarters in the SRS quarterly dosimeter results for 1966 (DuPont 

1966a, p. 23; DuPont 1966c, p. 125; DuPont 1966d, p. 115). SC&A reported gaps for the second and 
Document No. ORAUT-RPRT-0066 Revision No. 00 Effective Date: 09/19/2014 Page 9 of 23

fourth quarter of 1970, the first quarter of 1971, and the third quarter of 1972. The Team found those 

dosimeter result and area assignments in SRS quarterly dosimeter results (DuPont 1970a, p. 113; 

DuPont 1971a, p. 122; DuPont 1972d, p. 123).

Based on the data available in the SRDB and the dosimeter data available on microfiche at SRS, the 

Team concludes that there is only one verified gap for the Case 2 worker: the second quarter of 

1953. In the CATI, the claimant's survivor did state that the Case 2 worker worked in Building 773A or 

CMX/TNX.

3.3 CASE 3

The reported gaps for Case 3 were (1) missing dosimeter card and area code data for 1953;

(2) illegible area codes in 1955; (3) missing dosimeter card and area code data for all quarters of 1958 

and 1959, the second and third quarters of 1960, the third quarter of 1961, the first and second

quarters of 1962, the second and fourth quarters of 1963, the fourth quarter of 1964, the second, third, 

and fourth quarters 1965, the first and second quarters of 1966, the fourth quarter of 1969, the first, 

second, and third quarters of 1970, the fourth quarter of 1970, and the third quarter of 1972. In 

addition, SC&A reported 000 was listed for HP area code for the fourth quarter of 1963 and the first

quarter of 1964.

Visitor cards available to the Team begin in 1954. Therefore, the Team confirms a gap for 1953.

The Team examined the 1955 cards; the area code is A1, which is also a qualifying area code for the 

proposed SEC class (NIOSH 2011). The Team investigated SRS dosimetry quarterly reports and job 

history data for the Case 3 worker to search for explanations for the reported gaps in 1958 and 1959. 

The Case 3 worker was reassigned to clerical in 1956 and not monitored by film badge after July 1957 

and until the first quarter of 1960. SRS reported the worker was not monitored in 1958 and 1959,

although the worker was bioassayed in June 1959. Although the Team believes the Case 3 worker 

was not monitored for external dose based on work assignment, and although no dose was reported 

for 1958 and 1959, this worker was bioassayed in 1959. Therefore, the Team concludes there are 

possible gaps in area assignment for both years.

For the gaps in 1960, 1961, and 1962, SRS reported the worker’s total dose for each of those years. 

This indicates SRS considered those quarterly results to be the only periods of monitoring during 

those years. Health Physics evaluated the potential for exposure. Workers were assigned 

dosimeters when working in a Regulated or Radiation Danger Zone, or when there was the potential 

for external exposure (SRDB Ref ID: 52805). The worker was monitored when going into regulated or

radiation danger zones to perform material inventories. As an E&I control clerk the worker was 

tracking electronics and instruments in 1960-1961 timeframe with little potential for exposure and was 

not monitored for external exposure. The Case 3 worker’s external dose data is considered complete 

for 1960, 1961, and 1962 per the SRS data. For the fourth quarter of 1963 and the first quarter of

1964, SC&A reported the Case 3 worker’s HP area code was 000. The Team confirmed those 

assignments so the area code is no longer considered an issue.

The Team examined the SRS quarterly dosimeter results for the fourth quarter of 1964, second, third,

and fourth quarters of 1965, first and second quarters of 1966, fourth quarter of 1969, all four quarters 

of 1970, and third quarter of 1972 and found the assignments for each (DuPont 1964, p. 151; DuPont 

1965a, p. 146; DuPont 1965b, p. 149; DuPont 1965c, p. 150; DuPont 1966a, p. 157; DuPont 1966b, 

p. 154; DuPont 1969, p. 163; DuPont 1970b, p. 175; DuPont 1971a, p. 154; DuPont 1971b, p. 153; 

DuPont 1971c, p. 150; DuPont 1972d, p. 158).

Based on the data available in SRDB and dosimeter data available on microfiche at SRS, the Team

concludes that there are verified gaps for the Case 3 worker: 1953 and all quarters of 1958 and 1959. 

In the CATI, the claimant did mention that some work in Building 773A.

3.4 CASE 4

For the Case 4 worker, SC&A reported missing dosimeter card and area code data for January 1, 

1953, through January 5, 1954, and the receipt of data for the worker that appeared to be from a 

period outside the verified employment time frame (1967 to 1969).

Visitor cards available to the Team begin in 1954. Therefore, the Team confirms a gap for 1953. The 

Team searched visitor cards for 1954 but found no data for January 1 through January 5, 1954, for 

the Case 4 worker. The Team notes that the worker’s employment from December 11, 1951, through 

January 5, 1954, was verified by affidavit from a coworker. As SRS did not have a record of 

employment or record of monitoring in the visitor cards, it is most likely the worker was not monitored 

for radiation exposure during the early employment period.

The Team reviewed the data from outside the verified employment period. These data are single 

page copies of quarterly dosimetry reports for the first quarter of 1967, the third quarter of 1967, and 

the third quarter of 1968. These are supplemental reports uploaded by the Team but are not reports 

sent by DOE for the specific claim. In examining the complete claim file for the Case 4 worker, it is 

noted the last name of the worker contained a Sr. suffix in records sent by DOE, but there is no suffix 

on the supplemental dosimetry reports for 1967 and 1968. Furthermore, the payroll identification 

number for the worker in the 1967 and 1968 reports differs from the payroll identification number in 

1980-era dosimetry reports. The Team does acknowledge that a worker could have differing payroll 

identification numbers over time. However, SRS reported annual external dose for workers by social 

security number. For the Case 4 worker, SRS did not report any dose before 1983. Furthermore, in a 

DOE response in the claim file, SRS reported the first occupational medical X-ray for the worker to 

have occurred on July 14, 1983, (the date of hire in 1983). The Team proffers that the subject dose 

reports do not belong to the Case 4 worker because the employment was not verified and there is no 

evidence that the worker in the 1967 and 1968 reports is the same as the Case 4 worker.

Based on the data available in the SRDB and dosimeter data available on microfiche at SRS, the 

Team concludes that there are verified gaps for the Case 4 worker: all of 1953 and January 1 through 

January 5, 1954.

3.5 CASE 5

The reported issues for the Case 5 worker were (1) missing dosimeter card and area code data for 

1953, 1957, and the first three quarters of 1958; and (2) illegible area codes in the first quarter of

1954.

Visitor cards available to the Team begin in 1954; therefore, the Team confirms a gap for 1953. 

However, quarterly dosimetry reports included with the DOE response for the Case 5 worker show 

that employment began in November 1953. The Team reviewed the scanned copy of the film badge 

card for the first quarter of 1954 in the claimant file. The Team read the area code as D8 though it 

has been scratched out. The area code for 1953 was U and the area code for the third quarter of 

1954 was F. Bioassay for 1955 shows that the Case 5 worker worked in F area, which is consistent 

with the codes shown for 1953 and 1954. The area code may be readable on the microfiche copy of 

the first quarter of 1954 card at SRS. Because the area code can be determined to not be one of the 

area codes for 1954 in NIOSH 2011, the Team considers this issue to be resolved.
Document No. ORAUT-RPRT-0066 Revision No. 00 Effective Date: 09/19/2014 Page 11 of 23

The Team found no record of the Case 5 worker being monitored in 1957 and for the first three 

quarters of 1958. The Team researched the worker’s job history and found that the job accounting 

number prefix changed from G to GI in July 1956; the prefix remained GI through 1958. The GI prefix 

was handwritten next to the job accounting code. SRS reported the worker’s total dose for 1958 in 

the DOE response, so the 1958 data are complete. On that same report, SRS showed no monitoring 

during 1957. Although the worker’s job accounting number contained the GI prefix, the Team does 

not have enough information to determine if the worker should not have been monitored. Therefore, 

the Team verifies the gap for 1957 along with the gap for 1953. In the CATI, the claimant did not 

mention work in Building 773A or CMS/TNX, but did report working all over the site, which could imply 

773A or CMX/TNX.

3.6 CASE 6

The reported issues for the Case 6 worker were (1) missing dosimeter card and area code data for 

1953, 1959, the first, second, and the third quarters of 1960, the first, third, and fourth quarters of 

1961, the first, second, and the third quarters of 1962, the first quarter of 1963, all of 1966 and 1967, 

the second, third, and fourth quarters of 1970, all of 1971, and the first and second quarters of 1972;

and (2) illegible area codes for 1954 through 1957. In addition, the code 000 was listed for HP area

code for the second, third, and fourth quarters of 1963, all quarters of 1964, and the first and second 

quarters of 1965. This worked was in the Power department; as such, he was not likely exposed to 

radiation on a routine basis. Work would not have been routinely monitored (SRDB Ref ID: 52805).

Visitor cards available to the Team begin in 1954. Therefore, the Team confirms a gap for 1953. The 

Team attempted to read the area codes on film badge cards for 1954 through 1957 and agrees that 

the area codes on the scanned copies in the DOE response are not readable. However, the area 

codes (HP Area) would be readable on microfiche of the card available at DOE. Therefore, the Team

believes these issues of illegibility can be resolved.

The Team looked for external dosimeter results and area code data for 1959 in SRS quarterly 

dosimeter reports for that year. The Team found dosimeter records with area codes for the first, 

second, and fourth quarters (DuPont 1959c, p. 569). The Team researched the worker’s job history 

and found that the worker’s job accounting number prefix changed from G to GI in April 1959; the GI

prefix remained until October 1962. Although the worker’s job accounting number contained the GI

prefix, the Team does not have enough information to say the worker should not have been monitored 

in the third quarter of 1959 or that the worker was not on the site. Therefore, the Team verifies the 

gap for the third quarter of 1959. SRS reported total external dose for 1960, 1961, 1962, and 1963,

so the Team contends the quarterly reports in the file are the only reports for the worker for those 

years. Based on the SRS report and the GI accounting prefix, the Team considers 1960 through 

1963 complete.

In terms of the area code values of 000 for HP area code for the second, third, and fourth quarters of 

1963, all quarters of 1964, and the first and second quarters of 1965, the Team confirmed those 

assignments. However, the HP area code of 000 was added to the proposed class description by 

NIOSH after SC&A performed the cases review. Those issues are considered resolved.

The Team searched SRS quarterly dosimetry reports to determine if results were available for all 

quarters of 1966, 1967, the second, third, and fourth quarters of 1970, all of 1971, and the first and 

second quarters of 1972. The Team found dosimeter assignment and area code data for each of 

those quarters in the dosimetry reports for each respective quarter (DuPont 1966a, p. 80; DuPont 

1966b, p. 77; DuPont 1966c, p. 83; DuPont 1966d, p. 77; DuPont 1967a, p. 77; DuPont 1967b, p. 72; 

DuPont 1967c p. 80; DuPont 1967d, p. 90; DuPont 1970a, p. 76; DuPont 1970b, p. 105; DuPont 

1970c, p. 86; DuPont 1970d, p. 82; DuPont 1971a; DuPont 1971b, p. 82; DuPont 1971c, p. 79; 

DuPont 1972a, p. 75; DuPont 1972e, p. 47).

Based on the data available in the SRDB, the DOE claimant information, and the dosimeter data 

available on microfiche at SRS, the Team concludes that there are verified gaps for the Case 6 

worker: all of 1953 and the third quarter of 1959. In the CATI, the claimant’s survivor did mention 

Building 773A as one of the work locations for the Case 6 worker.

3.7 CASE 7

No issues were reported for the Case 7 worker’s records.

3.8 CASE 8

The reported issue for the Case 8 worker was illegible dosimeter card and area code data for 1954 

through 1958 and third quarter 1968. The Team reviewed the copies of the cards in the DOE 

response for the claimant. The Team concludes the area code is D; the 1 marking was marked out to 

denote just D. For the 1956 film badge card, the area code was changed to A9. For the 1957 film 

badge card, the area code was changed to D2, which refers to CMX/TNX. The film badge card for 

1958 refers to CMX/TNX as well. For the third quarter of 1968 in which the area code is not legible, 

the SRS dosimetry report for the third quarter of 1968 in the SRDB area contains a legible code (i.e., 

12G) (DuPont 1968c, p. 95). The Team considers all reported issues for Case 8 to be resolved.

3.9 CASE 9

The reported issues for the Case 9 worker were (1) illegible dosimeter card and area code data for the 

first and second quarters of 1968 and (2) missing results for all four quarters of 1972. The Team was 

able to clearly read the area code values for both the first and second quarter of reports for 1968; in 

both cases, the area code is 01B (DuPont 1968a, p. 96; DuPont 1968b, p. 89). The Team found 

dosimeter assignment and area code data for each quarter in 1972 in the dosimetry report for each 

respective quarter (DuPont 1972b, p. 53; DuPont 1972c, p. 87; DuPont 1972e, p. 55; DuPont 

1972f, p. 56). 

The Team finds that all reported issues for Case 9 have been resolved.

3.10 CASE 10

The reported issues for the Case 10 worker were (1) missing dosimeter card and area code data for 

all quarters of 1962 and 1963, and (2) the code 000 for HP area code for the third and fourth quarter 

of 1964.

The Team checked the work history information for the Case 10 worker. The Human Resources card 

for the worker shows termination for military service and reinstatement on December 5, 1963. The 

Team searched the dosimetry report for the fourth quarter of 1963 and found a dosimeter assignment 

for that period with area code 000 (DuPont 1963, p. 103). The Team verified the area code

assignment of 000 for the third quarter of 1964. The HP area code of 000 was added to the proposed 

class description by NIOSH after SC&A performed the cases review. A review of job history cards for 

two other workers that had military leave in the same time-frame also showed breaks in external 

monitoring.

The Team considers all reported issues for Case 10 to be resolved.

4.0 SUMMARY OF FINDINGS

SC&A (2011) identified 136 issues across 10 cases. The Team analyzed each case and examined 

the corresponding claimant CATI data, dosimetry reports, and work history information. As a result of 
Document No. ORAUT-RPRT-0066 Revision No. 00 Effective Date: 09/19/2014 Page 13 of 23

this effort, the Team believes that 120 (88%) of the issues are resolved. Of the 16 unresolved issues 

(12%) (see Table 4-1), five are from 1953, one from 1954, one from 1957, four from 1958, and five 

from 1959. The Team has resolved all gaps existing from January 1, 1960 forward or explained why 

monitoring was not performed. The unresolved issues affect 6 of the 10 cases; 9 of those issues 

pertain to Case 3. A numerical summary of the number of issues by year is provided in Table 4-2.
