| METAL THICKNESS GAUGE SHUTTER ASSEMBLY DAMAGED |
| |
| On 5/12/03 at 1500 CST, the shutter assembly on an IMS model TIAS-04 metal |
| thickness gauge became stuck and resulted in shutter assembly bolts |
| shearing. The gauge contains 50 curies of Cs-137. The licensee safed the |
| gauge by isolating air to the air-operated gauge. The manufacturer was |
| contacted and is currently on-site repairing the gauge. Additionally, |
| during the incident, the assistant RSO walked below the gauge without having |
| his radiation detection meter. Ion chambers mounted in the gauge area were |
| reading zero at the time. Area monitors mounted in the area were not in |
| alarm. The RSO has sent the assistant RSO's film badge out for processing. |
| |
| |
| The licensee has contacted Region 3 personnel (Sandy Frazier and Debbie |
| Piskura). |
