Advisory Board on Radiation and Worker Health
About the Advisory Board
The Advisory Board on Radiation and Worker Health (also referred to as the Advisory Board or the Board) was established by the President on December 7, 2000. The Advisory Board:
- Contains individuals from the public that represent a balance of scientific, medical, and worker points of view.
- Gives advice to the Department of Health and Human Services on its activities under the Act.
- Includes a balance of perspectives from scientists, physicians, and workers.
The Advisory Board operates under the specific guidelines of public laws. More information on how the Advisory Board operates can be found in:

Charter of the Advisory Board on Radiation and Worker Health [286 KB (3 pages)]
Re-established March 22, 2026 - Federal Advisory Committee Act–FACA (5 U.S.C. Appendix 2)
Responsibilities
The Advisory Board provides advice to the Secretary of the Department of Health and Human Services on:
- The development of the final rules on:
- Methods used for completing radiation dose reconstructions.
- Guidelines used to assess the likelihood that an employee’s cancer was caused by their work at a DOE or AWE facility.
- Procedures for adding additional classes of employees to the SEC.
- The scientific validity and quality of dose reconstruction efforts performed by NIOSH.
- Whether there is a class of employees who should be added to the SEC. The Advisory Board’s recommendation is based on:
- Whether the class of employees was exposed to radiation and it is not feasible to estimate their radiation dose.
- Whether there is reasonable likelihood that such radiation doses may have endangered the health of members of the class.
