| 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).                                                                    |
