Type of event:
accidental exposure to lost source
A worker with insufficient training disregarded signage associated with a radioactive source and disassembled a density gauge at a textile treatment planet, handling the 0.2-curie cesium-137 source for 30-45 minutes. He felt a burning sensation in one hand when he was done, and a few days later radiation injury was identified. Skin reddening and a lesion on one hand developed over the next two weeks. Localized dose was estimated as 3,000 rad and whole body dose as 20 rad.
