Section 333-109-0015 - Operating Procedures

(1) Particle accelerators, when not in operation must be secured to prevent unauthorized use.

(2) Written operating procedures pertaining to radiation safety must be established for each accelerator facility by the radiation safety officer.

(3) Written emergency procedures pertaining to radiation safety must be established by the radiation safety officer. These must list the telephone number(s) of the radiation safety officer and must include the following actions to be taken in case of a known, or suspected, accident involving radiation exposures:

(a) Notifying the radiation safety officer; and

(b) Arranging for medical examination.

(4) Personnel must not expose any part of their body to the radiation beam.

(5) Accelerator must not be left unattended while energized unless access to radiation areas or high radiation areas is physically prevented.

(6) All safety and warning devices, including interlocks, must be checked for proper operation at intervals not to exceed three months. Results of such tests must be maintained at the accelerator facility for inspection by the Authority.

(7) Records of personnel monitoring results and safety device tests must be maintained for inspection by the Authority.

(8) An appropriate radiation monitor must be used within an accelerator target room and other high radiation areas. This may be:

(a) An area monitor with an easily observable indicator that warns of radiation levels above a predetermined limit in accessible areas; and/or

(b) A personal radiation monitor of the "chirpie" type carried into the room; and/or

(c) A portable survey instrument carried into the room.

(9) Personal radiation dosimeters that measure the expected radiations and are of sufficient range to be useful under normal and accident conditions shall be worn by all persons designated by the radiation safety officer.

(10) Records of all radiation protection surveys, inspections and maintenance performed on the accelerator and related components must be kept current and on file at each accelerator facility, and maintained for inspection by the Authority.

(11) The safety interlock system must not be used to turn off the accelerator beam except in an emergency.

(12) Electrical circuit diagrams of the accelerator and the associated safety interlock systems must be kept current and maintained for inspection by the Authority and must be available to the operator at each accelerator facility.

(13) If, for any reason, it is necessary to intentionally bypass a safety interlock or interlocks, such action must be:

(a) Authorized by the radiation safety committee or radiation safety officer;

(b) Recorded in a permanent log and a notice posted at the accelerator control console; and

(c) Terminated as soon as possible.

(14) A copy of the current operating and the emergency procedures must be maintained at the accelerator control panel.
