Utility fined over nuclear prank

CHICAGO _ The Nuclear Regulatory Commission has fined Unicom Corp. $100,000 for an incident at an Illinois nuclear plant in which someone slipped a radioactive dime-sized foil disc into the hip pocket of a female worker.

The incident happened at Unicom's Quad Cities plant in Cordova, Ill. A spokesman for the utility said an FBI investigation into the Aug. 8 incident is continuing.

The disc, used to calibrate instrumentation, was discovered in the pocket of the woman's jeans after she set off radiation detectors inside the plant. An investigation determined that she had received an external dose of radioactivity equal to less than half the allowable annual limit.
