(w O o Report on Damace to Seal of Source Material Pursuant to 10CPR31.5(c)(5)

On June 6, 1985, Mr. T. J. Ireland, an employe of Oxford Instrument, was at the Fermi 2 site performing repairs to an oil analyzer supplied by Oxford. The analyzer is a Model Oxford Lab-X2000 x-ray fluorescence with an Iron-55 source of a maximum activity of 20 millicuries.

Normally, access to the cource material is not required to perform repairs. However, in this case the repairs did require access to the source material. Only the vendor has the keys to access the source material which was why it was necessary to have someone from Oxford perform the repairs.

While making an adjustment to the device, the surface covering of the source seal was scratched thereby permitting contamination by the Iron 55 source material.

This resulted in contamination of Mr. Ireland's hands to 400 cpm and to his trousers to 2000 cpm. The I contamination was found during a routine frisk, and no further contamination was detected on his person, or his clothing. It should be noted that all of the exposure levels were well below 10CPR20 limits.

Immediate corrective action taken included:

1. Decontamination of Mr. Ireland to less than 100 cpm.

His trousers had to be confiscated;

2. The oil analyzer was surveyed for loose contamination, then bagged and transferred to a controlled area;

3. Area surveys were performed as well as surveys of Mr.

Ireland's personal effects and his car. Minor levels of contamination were found on a work bench and were removed. No detectable contamination was found at the car.

4. The Radiation Safety Officer for Oxford was notified of the leaking source.

A representative for Oxford visited the Fermi 2 site to assess the situation and to arrange for transfer of the analyzer to their facility in Massachusetts.
