This bill, titled the Atomic Civilians Recognition and Compensation Act, aims to acknowledge and provide compensation for civilian employees and contractors who played crucial roles in the development and aftermath of the United States' atomic and nuclear weapons programs. It mandates the creation of an Atomic Civilians Commemorative Service Medal to honor their service and sacrifice. Eligibility for the medal extends to individuals who directly participated in atomic weapon detonations, radioactive material cleanups from atmospheric detonations or accidents, or were exposed to ionizing radiation from World War II atomic weapon use. The Secretary of Defense is responsible for designing, producing, and distributing this medal to eligible individuals or their next-of-kin upon application. Furthermore, the bill establishes a compensation program , subject to appropriations, offering a $75,000 award to eligible civilians and contractors. To qualify for compensation, individuals must have directly participated in radioactive material cleanup from atmospheric detonations or atomic weapon accidents and subsequently been diagnosed with one of a specified list of radiation-related diseases. Any compensation received under the Radiation Exposure Compensation Act will offset this award.
