On the morning of December 2, 2004, the Agency received telephone notification from BP Amoco Chemicals in Decatur,
Alabama, that on December 1, 2004 at 3:00 pm, the shutter handle of one their fixed
gauges containing radioactive material had broken. The company is licensed to possess and use the device under their
Alabama Radioactive Material License No. 256. The shutter of the
gauge, an
Ohmart model SH-F2-45, serial number 4789GK containing 500 millicuries of
Cesium-137 was in the closed position and when the licensee attempted to open the shutter, the shutter was found to be stuck and in the process of trying to open the shutter, the shutter handle broke. The handle is used to lock the shutter in place. Because the shutter was stuck in the closed position, no
overexposure of personnel occurred. The device has been isolated and an
Ohmart representative has been contacted to package the device and return the unit to
Ohmart for repair.
