Radiography was being performed at a steel fabrication shop when it was determined that the source could not be returned to the shielded position. The source was determined to be at the end of the tube. The camera was dragged to an isolated area and a 2 [milliRem/Hr] boundary was established. The crew (2 men) received about 130 [milliRem] exposure. The lab manager was called and responded. The guide tube was disconnected and the source shook from the tube. Using 4 [foot-long] tongs, the source was replaced in the exposure device. The lab manager received 2
Rem exposure during this process. The crank-to-source connections were subsequently inspected with the Amersham go-no go
gauge and found acceptable. Subsequent device operations have been faultless.
Florida is investigating.
The source is 51.6 Curies of
Iridium-192. The radiography camera belongs to Certified Testing Laboratories, Inc. of Orlando, FL. The State of
Florida incident number is FL04-094.
