SUBJECT:
UNPLANNED RADIATION EXPOSURE DUE TO MISHANDLING OF UNIDENTIFIED HIGHLY RADI0 ACTIVE SOURCES r
Recently there have been several events concerning unplanned radiation exposure as a result of mishandling unidentified highly radioactive sources.
On March 12, 1990, the New York Power Authority (NYPA) reported that a raciation technician had received an apparent exposure to the hand of 20-25 rem when he became contaminated while performing a radioisotope test of the reactor feed water flow rate using sodium-24. The contamination was found during frisking as the technician prepared to exit the radiological controlled area.
At THI-2 on September 25, 1989, two workers handled a piece of material later I
identified to be fuel debris. This resulted in a possible overexposure of the left hand of one of the workers.
At Point Beach on April 14, 1989, an ISI engineer received a dose to the hand of 4.7 rem during a closeout inspection of the unit B steam generator. The exposure occurred when the engineer picked up an object and passed it outside '
the steam generator without knowing that the object read 200 R/hr at near contact.
These events over the past year and possibly others suggest that an NRC-Information Notice is needed to focus more attention on improper handling of sources. Please contact Joe Wang at FTS 492-1147, or Jim Wigginton at FTS 492-1136, on the appropriateness of the proposed Information Notice and any other events and/or information that you are aware of that will help support the development of the proposed Information Notice. We plan to abstract these and any other significant events concerning extremity and/or wholebody exposures resulting from workers. improperly handling sources (some of which could overlap with the notice concerning spent fuel pool unplanned exposures),
