On October 4, 2010, the Arkansas Radiation … On October 4, 2010, the Arkansas Radiation Control Program was notified by Team Industrial Services, Arkansas license number ARK-0344-03320, involving the failure of a radiography source to retract into the camera. The radiography crew involved in this incident was based in Sulphur, Louisiana.</br>On October 3, 2010, radiography work was being conducted in Fulton, Arkansas using a rented SPEC-300 Camera, serial number 017, containing a 27 Curie SPEC G-70 source, serial number GE2503, both manufactured by Source Production and Equipment Company. The source was last leak tested on 10/1/2010. A J-Tube manufactured by QSA, owned by the licensee, was also employed in the radiography work.</br>The source was cranked out of the SPEC-300 and the radiographer was unable to retract the source back into the camera. The radiography crew contacted the RSO and the crew attempted to safely straighten out the guide tube. After realigning the guide tube, the source was retracted into the camera.</br>After the source was determined to be safely stored in the camera, the crew returned to the office to determine the cause of the inability to retract the source. SPEC was also notified.</br>At this time, no overexposures have been reported by the licensee.</br>The Radiation Control Program is awaiting a written report on the incident from the licensee.</br>Report #: ARK-0344-03320</br>* * * UPDATE FROM STEVE MACK TO ERIC SIMPSON AT 1500 EDT ON 10/22/10 * * *</br>The following report was received from the State of Arkansas via e-mail:</br>The (Arkansas Department of Health (ADH)) received a written report in accordance with RH-1801.k of the Arkansas Regulations describing the event, root cause and exposure information.</br>The SPEC G-70 source is a Cobalt-60 source.</br>During the initial exposure, it is believed that the source did not reach the end of the J-Tube and was temporarily 'hung up' at the connection between the guide tube and J-Tube. The radiography crew re-verified the controlled area boundaries and made notifications. After consulting with the local RSO for the radiography crew and the Corporate RSO an attempt was made to 'straighten' the guide tube to decrease the likelihood of any binding of the crank-out/source and the guide tube.
