AMERSHAM INDUSTRIAL RADIOGRAPHY CAMERA SOURCE FAILS TO RETRACT.
In Maidsville, West Virginia, this morning around 0540 ET an Amersham industrial radiography camera source failed to retract into its shielded position. The crank assembly, the remote handling part of the industrial radiography camera, has a lock on the crank assembly. After the radiographer had cranked the source out he placed the crank down and the lock tumbler went in and locked the control cable. After the shot had been taken the radiographer put the key in and pulled the lock assembly out but it failed to release the control cable which prevented the source from being retracted to its shielded position. While still at the controls the radiographer unscrewed a couple of threads on the control cable and manually pulled the 75 curie Iridium-192 source back to its shielded position. The radiographer picked up an additional 30 mrems due to manually pulling the source back to its shielded position. The licensee tagged the camera and ordered new equipment from Amersham to repair the camera.
