Nuclear Medicine Clarification Act of 2025

This bill clarifies when unintended radiation exposure in nuclear medicine must be reported to the Nuclear Regulatory Commission (NRC). It requires the NRC to revise regulations within 120 days to specify that a radiation dose from a leakage incident (extravasation) must be reported if it exceeds 0.5 Sv (50 rem) in either a 5 cubic centimeter tissue volume or 10 square centimeters of skin. The change directly affects hospitals and medical facilities using radioactive materials in procedures like diagnostic imaging or cancer treatment. The revised reporting threshold takes effect 18 months after the bill becomes law. This is a regulatory adjustment focused on defining specific exposure limits, not altering patient care or funding.
