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.
Qualifications of Industrial Radiographers.
MIL-STD-410, Nondestructive Testing Personnel Qualification and Certification, as amended, defines minimum
qualifications for radiography personnel (including recertification requirements).
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.
As a minimum, each radiographer must be instructed in those portions of the following subjects that apply to X
radiation and shall demonstrate understanding thereof.
Fundamentals of radiation safety
Characteristics of X and gamma radiation
a) Electromagnetic spectrum
b) Properties of X and gamma rays
Interaction of radiation with matter
b) Photoelectric effect
c) Compton effect
d) Pair production
Attenuation of radiation
a) Exponential function
b) Half-value layer (HVL) and tenth-value layer (TVL)
Inverse square law
b) Sky shine
Units of radiation measurement
