Section 120.710 - Radiation Monitoring Requirements

(A) There shall be available at each particle accelerator facility appropriate portable monitoring equipment which is operable and has been appropriately calibrated for the radiations being produced at the facility. Such equipment shall be tested for proper operation before use or once every three months, whichever is the lesser.

(B) A radiation protection survey shall be performed and documented by a qualified expert, acceptable to the Agency, when changes have been made in shielding, operation, equipment, or occupancy of adjacent areas.

(C) Radiation levels in all high radiation areas shall be continuously monitored. The monitoring devices shall be electrically independent of the accelerator control and safety interlock systems and capable of providing a readout at the control panel.

(D) All area monitors shall be calibrated at intervals not to exceed one year and after each servicing and repair.

(E) Whenever applicable, periodic surveys shall be made to determine the amount of airborne particulate radioactivity present.

(F) Whenever applicable, periodic smear surveys shall be made to determine the degree of contamination.

(G) All surveys shall be made in accordance with the written procedures established by a qualified expert, acceptable to the Agency, or the radiation safety officer.

(H) Records of all radiation protection surveys, calibrations, and instrumentation tests shall be maintained at the accelerator facility for inspection by the Agency.
