Louisiana Radiation Protection Division received the following information on August 6, 2003 from Source Production and Equipment Co., located in Saint Rose.
On August 5, 2003 a Hot Cell operator discovered material on the floor that was reading a high radiation level. He believed the source was a form of contamination which he attempted to clean up with his hand and a swipe. It was later discovered the same day that the source was a iridium-192 wafer that had inadvertently been released from the Hot Cell (the caller said that it took them fours hours to find out how the wafer got out of the Hot Cell). The persons radiation badge was sent in for a reading on August 6, 2003. Whole Body dose to the person from the badge was 157 millirems. Hand exposure calculation is still being investigated but the exposure to his hand ranges from 20 Rem to 700 Rems. Two weeks after the incident the person hand does not show any clinical indication to exposure to a high dose of radiation (no reddening). This event is under investigation.
The size of the iridium-192 wafer is approx. 0.1 inches in diameter, 0.01 inches in thickness with a total activity of 7.6 curies.
NRC Region 4 was notified of this event by Louisiana Radiation Protection Division.
