T.O. 33B-1-16-114c. Establish and maintain personnel monitoring program in conjunction with the Radiation Safety Officerand assure proper use and storage of personnel monitoring devices.d. Assure the availability, calibration, and proper maintenance of radiation survey instrumental.e. Maintain utilization logs. Assure that detailed procedures are implemented for maintaining anoperational log for each piece of equipment that will identify when interlocks and other control orwarning devices are bypassed or overridden (paragraph 9-9(b) 5, AR 40-5).f. Assume control and institute corrective actions in emergency.g. Investigate, in coordination with the Radiation Safety Officer, the cause of accidental and incidents toinclude suspected overexposures and unnecessary radiation exposures and determine necessary action toprevent recurrence of accidents and incidents and maintain all radiation exposures "As Low AsReasonably Achievable" (AR 385-40 and AR 40-14).h. Verify the competency of industrial radiographers to include assuring that only qualified 68D personnelwith ASI "N2" perform X-ray operation or use X-ray equipment and that only individuals authorized bythe applicable NRC license use gamma radiography sources.i. Assure that all radiation workers are subjected to medical surveillance in accordance with AR 40-14.6.9.3 QualificationsofIndustrialRadiographers.MIL-STD-410, Nondestructive Testing Personnel Qualification and Certification, as amended, defines minimumqualifications for radiography personnel (including recertification requirements).6.9.3.1 X-RaySources.All industrial radiographers must complete the approved course of instruction in the use of industrial X-ray equipment,including radiation hazards control, and demonstrate an understanding of acceptable practice.6.9.3.1.1 InitialTraining.As a minimum, each radiographer must be instructed in those portions of the following subjects that apply to Xradiation and shall demonstrate understanding thereof.A.
