ABRWH Potential SC&A Review Taskings for January 25, 2017

The Procedures Subcommittee recommends the following 2 procedures be tasked to SC&A for review:

• ORAUT-OTIB-0044: Historical Evaluation of the Film Badge Dosimetry Program at the Y-12 Facility in Oak Ridge, Tennessee: Part 1 – 

Gamma Radiation (ORAUT 2013a). This replaced OTIB-0013 of 2004 for individual workers’ dose adjustments. The Subcommittee reviewed 

OTIB-0013. OTIB-0044 is a substantial revision of the methods.

• ORAUT-OTIB-0064: Coworker External Dosimetry Data for the Y-12 National Security Complex (ORAUT 2013b). This replaced PROC-0042 

of 2004 for coworker dose assignments. The Subcommittee reviewed PROC-0042. OTIB 0064 is a substantial revision of the methods.

For the following four PERs, the Subcommittee recommends the PER be reviewed as well as the full DR methodology for 

three of these, all except Bridgeport Brass. The DR methodology has yet to be reviewed by SC&A for these other three 

sites. See recommendation notes in this regard.

PER Description Doses Changes Cases Impacted SC&A’s Recommendation

DCAS-PER-059: “Norton Company”

Effective Date: 4/24/2015

No TBD exists for Norton Company. However, a 

‘DR Methodology Template’ was used for 

completing claims, which has been modified.

Changes to the template include the addition 

of a class of employees to the SEC based on 

NIOSH’s inability to estimate internal and 

external dose between 1/1/1945 and 

10/10/1962. Also, contamination depletion 

rates changes during the residual period 

starting 10/10/1962 causing an increase in 

dose. 

54 initially identified cases.

43 cases remained after 

removing claim that had 

employment only prior to 

1962.

SC&A recommends that the 

PER be reviewed, since the 

dose reconstruction 

methodology used in the 

template has not been 

previously evaluated by the 

Board.

OCAS-PER-061: “Bridgeport Brass Company”

Effective Date: 6/5/2015

The TBD covers operations at the Bridgeport Brass 

Havens Laboratory in Bridgeport, CT as well as 

the Adrian Facility in Adrian, MI. This revision 

(Rev. 2) was issued due to a change in the facility 

designation for the Adrian Facility by the DOL.

Primary changes include (1) external dose 

was analyzed using OTIB-0020 in Rev. 1 of 

the TBD and using a Monte Carlo approach 

in Rev. 0, and (2) thorium intakes in Rev. 1 

were assigned based on air samples, and, in 

Rev. 0, thorium intakes were assigned as a 

fraction of the uranium intake.

14 cases identified at 

Haven’s Lab; 36 cases at 

Adrian Facility. All 50 cases

were reevaluated.

SC&A recommends that this 

PER be reviewed, since the 

only review of these 

facilities has been performed 

under an expanded review of 

a DR audit performed in 

May 2008.
PER Description Doses Changes Cases Impacted SC&A’s Recommendation

DCAS-PER-063: “Aluminum Company of 

America – Pennsylvania (ALCOA-PN)”

Effective Date: 6/15/2015

DRs are performed using Appendix R of BattelleTBD-6000. Revision 1 of TBD-6000 was issued 

to incorporate OTIB-0070 and other changes.

Revision 1 increased inhalation, ingestion, 

and external photon dose during the 

operation period.

44 cases initially identified.

35 cases were reevaluated.

SC&A recommends that this 

PER be reviewed, since the 

Board has not previously 

evaluated the ALCOA-PN 

DR methodology.

DCAS-PER-065: “Anaconda”

Effective Date: 11/30/2015

DRs are performed using Appendix G of BattelleTBD-6000. Revision 1 of TBD-6000 was issued 

to incorporate change to TBD-6000 and to make 

dose estimates more consistent with existing 

techniques.

External photon doses increased for all job 

categories in all years of operations.

10 cases identified and 

reevaluated.

SC&A recommends that this 

PER be reviewed, since the 

Board has not previously 

evaluated the Anaconda DR 

methodology.
