Transcript of Tape-recording USNRC -d March 1, 1983 96 JL 10 A9:47 At 9:00 this morning I contaminated my office with Co-60.

Approximately 20 microcuries I would es (ty gt: Moi 4K(15 different locations aproximately within my o ' 'TETgpc196 Ruff 3 people; myself, Joe Lupton, and Bill Pemberton. Wghwere trying to make radiographs with one of those hot speck, that we had captured from the vat below the high bay area some time ago and in doing the speck which was only about 10 micron in size, apparently ruptured the masking tape that it was on and the Saran wrap that was stuck over the source that was stuck to the masking tape apparently was radiation damaged. When we put it on the Polaroid film, it cross-contaminated the Polaroid film, that in turn cross-contaminated the Polaroid film developer. My hands became contaminated, about 6 millirem per hour on each hand. It's pretty hot contamination. This speck was oneper of those hot one from gamma industry days of about 100 Curies gram at this time. Part of this speck came loose and got on various things in the room and on 3 people. My right hair just above my ear was contaminated about 20,000 cpm with an E-120.

Joe Lupton's hands were contaminated about 10,000 cpm onfound an subsequently left the room before we E-120. He contamination in the room, while we were doing this and went to the restroom downstairs and cross-contaminated his vital organ.

We put him in the shower. He had about 600 cpm on his vital organ and he decontaminated very nicely. The water drained into any to be the hold tanks where it can be analyzed if there is washed completely. I took a shower following Joe's seen. I the shower. After we had frozen in the room and controlled contamination so that there was no contamination detected in Research Center (my the hall outside room 155 at the Nuclear office). It was an embarrasing thing and it was a kind of stupid thing on the part of the Radiological Safety Officer to assume that this speck would stay put and not cross-contaminate, but we took immediate action within about 3 minutes of the contamination and controlled it very nicely. It did take about 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> to get the place back to normal and some of the The items that got contaminated primarily were on my desk.

telephone was contaminated about 5,000 cpm on the receiver and one of the buttons. Some of my paperwork to the right on my desk got conteninated, my calculator was contaminated over 70,000 cpm with a Pancake E-120. The floor was contaminated in one spot down in the center of the room to about 50,000 cpm on an E-120. One of the geiger counters got contaminated toAll about of 6,000 cpm and serveral other items became contaminated.

it was controlled and kept in this room. Bill Pemberton's hands read about 600 cpm. He immediately washed them off in the decon room. As far as I can tell at this time and it is now 5:30 in i

the afternoon (my office was under control by 3:00) and there is no contamination of any significance left anywhere uncontrolled today. Dr. Russell was informed. We made the decision earlier that there was no need to make any report of this to the State l

and Federal people. This is not a reportable incident. Dr.

Carter was informed when we were at our height of cleaning up.

He was informed when it was cleaned up. This was an unfortunate situation that happened and we tackled it and I don't believe we will have any more problems with this one. All of the contaminant and the original speck were thrown in the radioactive waste can out in our barn and controlled properly.

Joe Lupton lost his trousers and I lost a sweater, a shirt, and my trousers. Steve Millspaugh was not in the room while we were trying to make these radiographs with this speck and he came to our aid and assisted us. Two of our student assistants assisted us. We used them as gofers to go get bags while we stayed in the room so we wouldn't spread the contamination. I think .in general we did a good job of controlling it. We were a little slow in getting our students to respond to the emergency because they had never had anything like this happen. It was understandable that they would not understand what was going on, but we controlled it very nicely and I see that we will be talking about this probably to the Committee at the next Radiation Protection Committee Meeting. No one took any unusual dose. I would say possibly if anybody took any dose I may have taken 6 to 10 millirem to the hands while we controlled the Everybody that. had contamination on their hands, Bill, area. '

Joe, and myself put gloves on so we controlled the contamination and then we could go wash our hands at a later time. But during the time while we were waiting I may have taken 6 to 10 millirem to my hands. At 5 minutes till 6 on March 1, 1983 I made a geiger counter probe survey up and down the hall from room 155 at the Nuclear Research Center where we had the contamination of  ;

cobalt today and now cleaned up. I wanted to make a check to see that we had none tracked down the hall and a last minute check. Checked the rug at the door leading out to Atlantic Drive and found no activity at any point. Went to the bathrooms, checked the doorknobs, checked all the knobs on the ]

plumbing, checked the floor as much as I could. I found no unusual activity above normal background at any point. l
