On July 28, 2016, the NRC issued a Notice of Violation and Proposed Imposition of a Civil Penalty in the amount of $7,000 to Applied Technical Services, Inc. (ATS), for a Severity Level III problem for three related violations. The violations involved: (1) a failure to conduct a survey of the camera guide tube after taking an image of a pipe weld in accordance with 10 CFR 34.49; (2) a deliberate failure to post an area where industrial radiography was being performed with conspicuous radiation or high radiation signs that established a radiological boundary as required by 10 CFR 34.53 and 10 CFR 20.1902; and (3) a failure to comply with a condition on the ATS State of Georgia license to ensure continuous direct visual surveillance of the operation to protect against unauthorized entry into a radiation area, as required by 10 CFR 150.20(b)(5). Specifically, on October 20, 2015, while conducting industrial radiography at the National Aeronautics Space Administration Langley Research Center in Hampton, Virginia, after completing an exposure of a pipe weld, a radiographer approached the camera and the guide tube without a survey meter and did not conduct a survey of the camera to ensure that the source had been retracted. The radiographer did not post accessible portions of the radiation area with radiation or high radiation signs and the radiographer did not comply with provisions of State of Georgia license to ensure continuous direct visual surveillance of the operation to protect against unauthorized entry into a radiation area or high radiation area. As a result an NRC inspector was allowed to walk unnoticed and unimpeded into the radiation area while radiographic operation were being performed.
