PERSONAL ITEMS WITH LOW LEVEL CONTAMINATION FCUND OFFSITE On May 17, 1989, one member of an eight person crew that had been working on the refueling floor alarmed the PCM-1B whole body frisker. It was determined that his socks were contaminated to approximately 200 counts per minute (cpm) over background.

Due to the location of the contamination on the individual and the limited number of potentially contaminated work areas at the site, the licensee narrowed the source of the contamination to a dressing area on the level below the refueling floor and concluded that only the eight individuals were likely involved. Since the time the contamination originated in the dressing area was unknown, the licensee, as a precautionary measure, surveyed the temporary residences of the crew members and found four pairs of socks and one pair of shoes with low levels of contamination, approximately 150-600 cpm. No other individuals were affected and no other offsite contamination was found. Follow-up whole body counts of all crew members were negative. The licensee informed the State of Vermont on May 18 and the Commonwealth of Massachusetts (where two workers temporarily resided) were informed on May 19. A Commonwealth representative accompanied the licensee during a survey of the workers' amporary residence.

.The Resident Inspector was first informed of this event on May 18, 1989. This information is current as of 10:00 a.m. (EDT), May 23, 1989. A Region I radiation specialist will followup on this incident during the next regularly scheduled inspection. Region I will respond to any news media inquiries.
