Uranium Miners and Workers Act of 2023

This bill expands eligibility under the Radiation Exposure Compensation Act (RECA) for uranium miners, mill workers, ore transporters, and core drillers who were exposed to radiation between 1942 and 1978. It requires claimants to provide medical documentation linking their illness (like lung cancer or kidney disease) to that exposure. The bill transfers $475 million from unused coronavirus relief funds to the RECA trust fund and extends the deadline for filing claims from 2 to 4 years after enactment. This directly affects workers in specific states (including Arizona, Colorado, and New Mexico) who developed radiation-related illnesses after working in uranium-related industries during the specified period.
