AGREEMENT STATE - LOUISIANA - TROXLER GAUGE MALFUNCTION

The State provided the following information via facsimile:

"On March 5, 2007 there was a malfunction with a Troxler gauge. After performing a moisture/density test, the technician squeezed the release handle, pulled up the rod, and walked away from the test location. While walking towards the truck, an assistant told the technician that he had dropped something. When the technician looked, [he] realized that the object that had fallen was the bottom piece on the Troxler gauge rod. The technician told the assistant to stay away from the broken piece. The technician then carefully picked up the piece with a shovel from the truck and placed it on the tailgate. A brief observation of the broken rod was taken by the technician to assure that the [source] pellet was still in place and not dropped on the ground. He than noticed that the weld on the rod was the main cause of the problem. At this time the technician immediately staked out the area and called his equipment manager - a repair technician [redacted] with Gamma-Tron, and his Supervisor [redacted] He then shoveled the broken rod into the containment box were the gauge was located. It was locked and secured as he transported it to the company equipment container were it was placed and double locked for safety. A sign was placed at the container to keep other employees from disturbing the gauge. All of the previously mentioned personnel were contacted and made aware of the situation. On March 6, 2007, [the technician] from Gamma-Tron placed the source back into the safe position. [The technician from Gamma-Tron] assured the facility that the radioactivity was controlled. [The technician] then took the gauge to QSA Global so the unit could be disposed of properly."

PERSONNEL OVEREXPOSURE ASSEMBLING PALLADIUM SEEDS

On 3/26/07, the licensee's RSO received dosimetry reading (from Landauer) on employees working at his facility indicating that a worker had a deep dose exposure of 9683 mrem and an extremity dose of 9200 mrem. This exposure occurred sometime over the previous two months - the measured dose period was from 1/01/07 to 3/01/07. The individual with the potential overexposure works in the fabrication of Palladium - 103 seeds, a soft gamma emitter, used for brachytherapy treatment. The cause of the overexposure is currently unknown. The dosimetry of coworkers does not indicate overexposures. A survey of the work area shows no contamination and no previously unidentified possible sources of exposure. The worker is a female, approximately 30 years old, and does not exhibit any medical symptoms. No information on pregnancy status was available. Interviews with the individual are in progress.
