To amend title 38, United States Code, to revise the eligibility criteria for presumption of service-connection of certain diseases and disabilities for veterans exposed to ionizing radiation during military service.

This bill aims to make it easier for veterans who were exposed to radiation during their military service to qualify for disability benefits. It would expand the definition of "radiation-risk activity" to include exposure to residual contamination from nuclear detonations, regardless of whether a specific level of radiation was officially measured for that individual at the time. By removing the requirement for a recorded dose of radiation, the bill would allow more veterans suffering from related illnesses to receive medical care and compensation from the Department of Veterans Affairs.
