San Onofre

Six workers received minor doses of radiation from an X-ray machine that shorted at the San Onofre Nuclear Power Plant, Southern California Edison Co. said. A spokesman for the utility said the accident Friday had nothing to do with the plant’s nuclear facility. The machine, used routinely to X-ray pipe welds, shorted and a highly radioactive probe could not be retracted. Workers had to shield and remove the probe manually, exposing them to radiation of up to 100 millirems, the spokesman said. The maximum dosage authorized for any employee is 1,250 millirems for any three-month period.
