c. Establish and maintain personnel monitoring program in conjunction with the Radiation Safety Officer
and 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 an
operational log for each piece of equipment that will identify when interlocks and other control or
warning 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 to
include suspected overexposures and unnecessary radiation exposures and determine necessary action to
prevent recurrence of accidents and incidents and maintain all radiation exposures "As Low As
Reasonably Achievable" (AR 385-40 and AR 40-14).
h. Verify the competency of industrial radiographers to include assuring that only qualified 68D personnel
with ASI "N2" perform X-ray operation or use X-ray equipment and that only individuals authorized by
the applicable NRC license use gamma radiography sources.
i. Assure that all radiation workers are subjected to medical surveillance in accordance with AR 40-14.
