This bill directs the Defense Department's Assistant Secretary for Nuclear, Chemical, and Biological Defense to commission an independent scientific study on whether partial body radiation shielding that protects bone marrow can improve human survival rates after exposure to gamma radiation from nuclear events. The study, to be conducted by a university research center affiliated with U.S. Strategic Command, will review existing peer-reviewed scientific literature, lab studies, and experimental data to evaluate how bone marrow shielding affects the likelihood and severity of acute radiation syndrome and overall mortality rates. The Assistant Secretary must enter into an agreement with the research center within 30 days of the bill's enactment and must submit a report with the study's findings to the House and Senate Armed Services Committees within 150 days. The bill does not specify any funding amount, though it establishes a relatively tight timeline for completing this research assessment. This legislation primarily affects military and defense policy officials responsible for nuclear survivability planning and preparedness.
