U.S. NRC Final Policy Statement on Security of Cs-137 Chloride Sources
The Nuclear Regulatory Commission (NRC) has issued its final policy statement on the protection of sealed radiation sources containing cesium-137 chloride (CsCl). Cesium chloride sources have received special attention because the CsCl powder is highly soluble and dispersible, which makes it attractive for use in a radiological dispersal device. The policy statement emphasizes that cesium chloride sources are adequately protected under current NRC requirements, and that the NRC encourages voluntary design improvements that could further enhance their security. The statement also encourages development of alternative forms of cesium-137 and calls for the elaboration of a strategy for long-term storage and disposal of CsCl sources whether or not alternative forms are developed.
