Current through Register Vol. 48, No. 9, September 27, 2024

6.4.1 There shall be available at each particle accelerator facility appropriate portable monitoring equipment which is operable and has been appropriately calibrated for the radiation energy levels being produced at the facility.

6.4.2 A radiation protection survey shall be performed and documented by a qualified expert, acceptable to the Department, at intervals not to exceed three months and when changes have been made in shielding, operation, equipment, workload, or occupancy of adjacent areas.

6.4.2.1 All surveys shall be made in accordance with the written procedures established by a qualified expert acceptable to the Department and the Radiation Safety Officer.

6.4.2.2 All surveys shall include a diagram of the machine and adjacent areas including, but not limited to, the operator's area at the control panel.

6.4.2.3 All survey results shall be recorded using quantified units of radiation at each survey point.

6.4.3 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.

6.4.4 Personnel entering a target room or high radiation area shall use a radiation monitor capable of producing an audible alarm or "chirp" in the presence of radiation. The alarm shall be fully functional and checked for operability in accordance with RHC 6.4.6.

6.4.5 All area monitors and survey instruments shall be calibrated at intervals not to exceed one year and after each servicing and repair.

6.4.6 The operator shall check each survey instrument for proper operation with a dedicated check source each day in which the instrument is used to ensure the instrument is operating properly.

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

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

6.4.9 Records of all radiation protection surveys, calibrations, and instrumentation tests shall be maintained at the accelerator facility for inspection by the Department. The registrant shall retain these records for five years or until the next Department inspection, whichever is later.
