Claims Based on Exposure to Ionizing Radiation (Radiogenic Diseases)

This document amends the Department of Veterans Affairs (VA) adjudication regulations concerning claims based on exposure to ionizing radiation. This amendment is necessary to implement a decision by the United States Court of Appeals for the Federal Circuit and recent legislation providing that VA's regulatory list of radiogenic diseases is no longer an exclusive list of conditions which may be considered service-connected solely on the basis of exposure to ionizing radiation. The effect of this amendment is to provide claimants who base their claims on conditions not on that regulatory list an opportunity to establish service connection by demonstrating that their conditions are radiogenic diseases.
