37.14.1430 RADIATION MONITORING REQUIREMENTS
(1) There shall be available at each particle accelerator facility appropriate portable monitoring equipment which is operable and has been calibrated for the appropriate radiations being produced at the facility. Such equipment shall be tested for proper operation daily and calibrated at intervals not to exceed 1 year and after each servicing and repair.
(2) A radiation protection survey shall be performed and documented by a qualified expert specifically approved by the department when changes have been made in shielding, operation, equipment, or occupancy of adjacent areas.
(3) Radiation levels in all high radiation areas shall be continuously monitored. The monitoring devices shall be electrically independent of the accelerator control and interlock systems and capable of providing a remote and local readout with visual or audible alarms at both the control panel and at entrance to high radiation areas, and other appropriate locations, so that people entering or present become aware of the existence of the hazard.
(4) All area monitors shall be calibrated at intervals not to exceed 1 year and after each servicing and repair.
(5) Whenever applicable, periodic surveys shall be made to determine the amount of airborne particulate radioactivity present in areas of airborne hazards.
(6) Whenever applicable, periodic smear surveys shall be made to determine the degree of contamination in target and other pertinent areas.
(7) All area surveys shall be made in accordance with the written procedures established by a qualified expert or the radiation safety officer of the particle accelerator facility.
(8) Records of all radiation protection surveys, calibration results, instrumentation tests, and smear results shall be kept current and on file at each accelerator facility.
