We are taking steps to continue to modernize and secure our data, applications, and systems. We completed the first phase and restored many of the functions put on pause in May 2021. Now that the first phase is complete, work will resume at a slower pace but will speed up as new systems and applications are brought online. For more information and updates, please visit our Cybersecurity Modernization Initiative web page.

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.
