NAC459.750. Safety requirements: Monitoring.

     1. There must be available at each particle accelerator facility appropriate portable monitoring equipment which is operable and calibrated for the appropriate radiations being produced at the facility. This equipment must be tested for proper operation daily and calibrated at intervals of not more than 1 year and after each servicing and repair.

     2. A radiation protection survey must be performed and documented by a qualified expert specifically approved by the Division when changes have been made in shielding, operation, equipment or occupancy of adjacent areas.

     3. Radiation levels in all high radiation areas must be continuously monitored. The monitoring devices must be electrically independent of the accelerator control and interlock systems and capable of providing a remote and local readout with visual or audible alarms, or both, at the control panel, at the entrance to high radiation areas and at other appropriate locations so that persons entering or present become aware of the existence of the hazard.

     4. All area monitors must be calibrated at intervals of not more than 1 year and after each servicing and repair.

     5. Whenever applicable, periodic surveys must be made to determine the amount of airborne particulate radioactivity present in areas of airborne hazards.

     6. Whenever applicable, periodic smear surveys must be made to determine the degree of contamination in target and other pertinent areas.

     7. All area surveys must 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 must be kept current and on file at each accelerator facility.
