Section R. 325.5452 - Radiation surveysRule 452.
(1) A licensee or registrant shall maintain at each accelerator installation appropriate calibrated and operable portable radiation monitoring instruments to make physical radiation surveys as required by this part and part 5.(2) Portable radiation monitoring 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 intervals not to exceed 3 months.(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 in accord with Rule 221 when changes have been made in shielding, operation, equipment, or occupancy of adjacent areas, and periodically to check for unknown changes and malfunctioning equipment.(5) Whenever applicable, periodic surveys shall be made to determine the amount of airborne 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 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.Mich.
