Document Number: ORAUT-RPRT-0057 Rev. 00
Approved: March 7, 2013
About this Document: This report defines a dose reconstruction method for Mound workers who may have been incidentally exposed to stable metal tritide (SMT) compounds in the SW/R Tritium Complex (SRTC), but who were not assigned to directly handle SMTs. SMTs are type S tritium compounds that are insoluble in lung fluids. The method defines an annual intake of SMTs based on a claimant-favorable estimate of removable tritium surface contamination, a chronic resuspension factor (5 ×10-5 m-1) that modifies the surface contamination level resulting in an airborne radioactivity concentration, and full-time worker occupancy (2000 hr/yr) in the contaminated area. The method is applicable for the period March 6, 1980 through December 31, 1999. March 5, 1980 is the date when SEC-00171, which covers every potentially-exposed tritium worker, ends. December 31, 1999 is the date when there is confidence that the dosimetric problems associated with SMT exposure were adequately addressed by the Mound radiation safety staff. The method may also be useful for reconstruction of doses associated with non-presumptive cancers during the SEC-00171 period. Incorporates formal internal and NIOSH review comments.

Advisory Board on Radiation and Worker Health Comments on Policy, Procedure, and Guidance Documents
The Advisory Board conducts technical reviews of various DCAS policy, procedure, and guidance documents that relate to dose reconstruction. The Board’s technical support contractor assists in the review process. The purpose of the reviews is to assess the scientific and technical quality of the methods used in dose reconstruction. They also help identify any deficiencies that could have a negative effect on the results or the dose reconstruction process. These reviews can be found on the Advisory Board: Reports from the Technical Support Contractor page of our website.
When the reviews are complete and all issues have been resolved, the Board prepares a brief summary of the resolutions. The summaries help the public understand the results of the technical reviews. These summaries can be found on the Advisory Board: Technical Review Summaries from the Technical Support Contractor page.
