(a) A user conducting shielded-room radiography
shall designate an individual as the radiation safety officer. This individual shall
meet the criteria specified in section
30336.7.
(b) A user shall not allow any individual to
perform shielded-room radiography unless the individual:
(1) Has completed the training specified in
section
30335.10 from a provider approved
pursuant to section
30331;
(2) Has received copies of, instruction in, and
demonstrated understanding of, the user's operating and emergency procedures by
obtaining a passing grade of at least 80 percent on a written examination covering
this material. The written examination shall be at least 50 questions in length.
Instruction in this material shall be at least eight hours long; and
(3) Has demonstrated competence to use the
radiation machines and survey instruments employed by the user and in the kinds of
radiographic operations that will be performed by obtaining a passing grade of at
least 80 percent on a practical examination covering this material. The practical
examination shall be at least 25 questions in length. Instruction in this material
shall be at least four hours long.
(c) A user shall supply personnel dosimeters to
and require the use by every individual who operates, who makes "setups," or who
performs maintenance on a shielded-room radiography unit. Each personnel dosimeter
shall be assigned to and worn by only one individual and processed in accordance
with section
30333.2(b). Reports
received from the dosimetry processor shall be available for inspection and
maintained until the Department terminates the user's registration. If a personnel
dosimeter is lost or damaged during radiographic operations, the worker shall
immediately cease work using radiation sources until a replacement personnel
dosimeter is provided and the exposure is calculated for the time period from
issuance to loss or damage of the personnel dosimeter. The radiation safety officer
shall perform the calculation. The results with measurements, calculated data, and
assumptions made to obtain the calculated exposure and the time period for which the
personnel dosimeter was lost or damaged shall be retained for inspection until the
Department terminates the user's registration.
(d) All openings through which an individual could
gain access to the room shall be interlocked so that the radiation machine will not
operate unless all openings are securely closed. The required controls shall be
designed such that an individual is not prevented from leaving the room.
(e) The room shall not be occupied during
radiation exposures.
(f) A device shall
be installed within the room that will, upon actuation, terminate production of
radiation. It shall not be possible to reset, override, or bypass the device from
outside the room.
(g) Radiation machines
used in shielded-room radiography shall meet the requirements specified in American
National Standard N537-1976 "Radiological Safety Standard for the Design of
Radiographic and Fluoroscopic Industrial X-ray Equipment" published as NBS Handbook
123, issued August 1977 [FN*], which is incorporated by reference.
(h) The interior of the room shall be shielded so
that every location on the exterior does not exceed the dose limits for an
unrestricted area as specified in 10 CFR
20, subpart D incorporated by
reference in section
30253.
(i) Documentation demonstrating compliance with
this section shall be maintained for three years and kept available for inspection.
