Disease Subject to Presumptive Service Connection (Radiation Risk Activity)

This document amends Department of Veterans Affairs (VA) adjudication regulations concerning diseases presumed to be the result of exposure to ionizing radiation. This amendment is necessary to implement Public Law 103-446, the Veterans' Benefits Improvements Act, which provides that the term ``radiation risk activity'' includes the onsite participation in a test involving the atmospheric detonation of a nuclear device by the United States and by other governments. The intended effect of this amendment is to extend the presumption of service connection for radiogenic disabilities to those veterans exposed to radiation during active military service due to onsite participation in atmospheric nuclear tests conducted by nations other than the United States.
