DEP [Department of Environmental Protection] received a letter dated March 9, 2009 from Acuren describing the incident. It was received March 16, 2009.
Event Description: A technician was performing radiography in Erie, PA (Booth #2) at 8:55am. A few seconds after his fourth exposure, the technician heard the spool piece fall off the table. He immediately tried to retract the source but was unsuccessful. The RSO traveled to the facility, calculated the exposure rates and executed a safe retrieval of the source. He received 35 mrem of exposure during the retrieval. The damaged guide tube was disposed. A 1.75" lead sheet was used to shield the source while the guide tube was reshaped to allow a safe retrieval to the secured position. A whole body dose of 32 mrem was received by retrieval technician.
Causes of the event: Spool piece was not properly secured in a safe position on the table. Piece was not properly blocked or braced, and located too close to the end of the table, so any movement would result in a fall. The jack stands that were available were not used, nor was shooting the parts on the floor considered. Guide tube and camera were not properly positioned to avoid contact with falling spool piece.
