AGREEMENT STATE REPORT - MALFUNCTION OF LOCKING MECHANISM ON RADIOGRAPHY EXPOSURE DEVICE

The following was reported by the New Mexico Radiological Health Division via email:

"Desert NDT (dba Midwest Inspection Services) reported a malfunction with the locking mechanism on a radiography exposure device (INC model IR-100, serial #4644). The incident involved an Ir-192 source (INC model 32, serial #X717) with an activity of 3,589 GBq (97 Ci). After completing an exposure on 1/12/2015 [at a temporary job site near Malaga, NM], the radiographer performed radiation surveys on the radiography device and noted that readings were high. The radiographer attempted to crank the source into the fully shielded position, but was unsuccessful. The 2 mR/hour boundary was verified and the RSO was contacted. The RSO responded to the site and had to drill a hole in the retaining ring on the locking mechanism. By pulling the retaining ring back, he was able to turn the key, push the button, and retract the source. The exposure device locking mechanism was replaced.

AGREEMENT STATE REPORT - UNABLE TO RETRACT SOURCE DUE TO CRIMPED GUIDE TUBE

The following report was received from the Texas Department of State Health Services via email:

"On June 29, 2017, the Agency [Texas Department of State Health Services] was notified by a licensee's radiation safety officer (RSO) that one of his radiography crews experienced an event. The radiographers were testing a 24 inch pipe and the shoots required the use of an extension on the guide tube and the use of a stand. While retracting the 56 curie iridium-192 source back to the QSA 880D camera, the stand fell on the guide tube extension crimping it far enough that the source could not be retracted beyond the crimp. The radiographers set up new boundaries and contacted the RSO. The RSO stated the source was driven to the end of the guide tube and shielding was placed over the source. The guide tube extension was removed from the camera and disconnected from the guide tube. The crank out assembly was dismantled and the drive cable was pulled through the camera and guide tube extension. The cable was inserted through the camera and the source retracted into the exposure device. The individual who recovered the source received 287 millirem (as indicated on their self-reading dosimeter.) The equipment was delivered to the manufacturer for inspection and repair or disposal. Additional information will be provided as it is received in accordance with SA-300.
