The authors conduct a cost-benefit analysis of replacing cesium-chloride blood irradiators with x-ray blood irradiators to reduce the threat of cesium-chloride being diverted to a radiological dispersal device, which combines conventional explosives with radioactive material to contaminate people and the environment. Although such a device would not cause mass casualties, it is a potential terrorist weapon because it can deny use of a large area, causing economic losses. Cesium-chloride irradiators have been identified as presenting a significant risk as a domestic source of radiological material for use in radiological dispersal devices. The authors find positive net benefits for switching from cesium-chloride to x-ray irradiators in almost every case; however, because the net benefits are much larger and more certain for older devices, they recommend planning the replacements in phases in order to replace the oldest irradiators first.
