  • Technical Documents Used in Dose Reconstruction

    About these Documents: Technical documents are general working documents that provide historic background information and guidance to assist in the preparation of dose reconstructions at particular sites or categories of sites. They will be revised in the event additional relevant information is obtained about the affected site(s). These documents may be used to assist NIOSH staff in the completion of the individual work required for each dose reconstruction.

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.
