The following report was received from the … The following report was received from the State of Colorado via email:</br>Event description: The department (Colorado Department of Public Health and Environment) was notified via phone on 9/23/2014, at approximately 1845 (MDT) by the Radiation Safety Officer (RSO) of Premier NDT Services, Inc. (license # CO 1162-01) that a radiography crew was unable to retract the source assembly to its fully shielded position and secure it in this position at a temporary job site.</br>At approximately, 1900 (MDT) on 9/23, the RSO reported to the department (Colorado Department of Public Health and Environment) that the source had been retracted to it fully shielded position by working the crank back and forth a few times. It was about a quarter turn to get the source into position and have the exposure device lock engage. The source was not fully extended outside of the camera but was in the camera enough to close the outlet port cover.</br>The radiography camera was surveyed and it was determined that the source was in fact in its fully shielded position prior to transporting the camera back to the licensee facility.</br>The department (Colorado Department of Public Health and Environment) visited the licensee facility on 9/24/14, at approximately 0930 (MDT) and interviewed licensee staff including the radiography crew.</br>It was determined that the radiography assistant had not properly surveyed during the approach to the camera to verify that the source was in fact in its fully shielded position and that he disconnected the guide tube prior to realizing that the source was not fully shielded. When he attempted to disconnect the drive cable he realized that the exposure device lock was not engaged properly and the crew retreated to a safe distance.</br>There were two assistant radiographers and a radiographer present and their pocket dosimeters read 10, 9 , and 20 mrem after the event. It appears unlikely that this is an overexposure event. The time in which the crew was in close proximity to the camera with the source out of its secured position was less than 5 minutes total and the time in which the crew member was in contact with the camera was less than a second to disconnect the guide tube and close the outlet port cover and another second when he attempted to disconnect the drive cable.</br>It is suspected that this was a malfunction of the device. The camera (QSA 880 Delta), drive cables, and guide tube are being sent back to the manufacturer for diagnosis.</br>The department (Colorado Department of Public Health and Environment) is preparing a Notice Of Violation for multiple items and is expecting a full report from the licensee within 30 days including dose estimates.</br>Event Report ID No.: CO14-I14-26stimates.
