Last of Cs-137 irradiators removed from South Carolina
The Department of Energy’s National Nuclear Security Administration announced that it has successfully removed all cesium-137 irradiators from South Carolina, as the agency seeks to eliminate radiological threats and protect communities.
Cs-137 sources are commonly used to irradiate cellular blood cells prior to transfusion to prevent graft-versus-host disease, where the donated cells view the recipient’s cells as an unfamiliar threat. If stolen from a less-secure facility, however, the cesium inside the irradiators could be used to create a radiological dispersal device, commonly referred to as a dirty bomb.
