R 333.5452 Radiation surveys.

Rule 452. (1) A registrant shall maintain at each accelerator installation or class D operation appropriate calibrated and operable portable radiation monitoring instruments to make physical radiation surveys as required by this part and R 333.5051 to R 333.5089. (2) These instruments shall be capable by design, calibration, and operation of measuring the intensity of the various types and energies of radiation produced by the accelerator. These instruments shall be tested for proper operation at the beginning of each day they are to be used and calibrated at least quarterly. (3) During repair or calibration of a radiation monitoring instrument, a spare calibrated and operable instrument shall be provided or accelerator operations which require the instrument shall be terminated until required instrumentation is available. (4) A radiation protection survey shall be performed and documented pursuant to R 333.5063 when changes have been made in shielding, operation, equipment, or occupancy of adjacent areas. (5) Radiation levels in all accessible high radiation areas shall be continuously monitored except in installations designed for human exposure. The monitoring devices shall be independent and capable of providing a remote and local readout with visual or audible alarms, or both, at the control panel and at the monitoring stations. (6) All area monitors shall be calibrated at established periodic intervals approved by the department. (7) All area surveys shall be made as specified in the written procedures established by a health physics consultant or the radiation protection supervisor of the accelerator facility and approved by the department. (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.
