Although responsibility for safe use of sealed sources remains with the contractor pursuant to the
contractor's license, RSOs must review operating procedures to verify compliance with applicable
regulations and to assure that Army personnel and property are protected.
6.9.5
Radiation Safety Monitors.
Radiation safety monitors are qualified radiographers who work under the direct supervision of the radiographer in
charge.
6.9.5.1
Training.
Radiation safety monitors for both X-ray and gamma-ray sources will receive training in the subject areas listed in 10
CFR 19 as well as training commensurate with their assigned duties to include applicable elements specified in
paragraph 9-10d(1) therein.
6.9.5.2
Duties.
a. Operate radiation survey meters.
b. Establish location of radiation barriers.
c. Set up personnel barriers.
d. Prevent unauthorized personnel from entering a radiation area.
e. Record radiation intensity reading at barriers.
f. Record personnel pocket dosimeter reading.
g. Utilize dosimetry devices as specified by the Radiation Safety Officer.
h. Perform other duties as directed by the radiographer in charge.
6.9.6
Radiation Safety Monitor Assistants.
Radiation Safety Monitor Assistants are those persons who assist the radiographer and/or the Radiation Safety Monitor
in preventing unauthorized access into radiographic inspection areas. Safety assistants are not authorized inside the
radiation area during irradiation. Assistants will be stationed outside the radiation area but in such a location as to be
able to monitor the barrier and to prevent barrier penetration. Assistants will at all times be in direct vision or contact
with the safety monitor or radiographers to effect radiation termination if required. If this is not possible, adequate
means of communication SHALL be specified by the local RSO during a survey of the radiographic inspection area and
operation. Adequate means of communication may include, but need not be limited to, two-way radios, whistles,
electronic/propellant activated noise alarms or ultrasonic/infrared intrusion barriers. Assistants will receive their
instructions directly from the radiographer in charge or the Radiation Safety Monitor, but not from another assistant.
6.9.6.1
Training.
As mandated by 10 CFR 19, assistants shall receive, as a minimum, radiation safety training covering the following
items: properties of X and gamma rays, hazards of excessive exposure to radiation, methods of measuring radiation,
radiation protection, and operation of specific measurement devices that will be used. This training must be conducted
by a qualified radiographer, Bioenvironmental Engineer or Radiation Safety Officer and documented in the individual's
training record or the Maintenance Management Information Control System (MMICS). Refresher training SHALL be
conducted annually.
6.9.6.2
Duties.
a. Operate radiation survey meters.
