N. C. Regulations for Protection Against Radiation

15A NCAC 11 .0909          RADIATION MONITORING REQUIREMENTS

(a)  Portable monitoring equipment shall be available at each particle accelerator facility.  Such equipment shall be tested for proper operation monthly and calibrated at intervals not to exceed one year, and after each servicing and repair.

(b)  A radiation protection survey shall be performed and documented by a qualified expert registered by the agency pursuant to Rule .0205 of this Chapter, when changes have been made in shielding, operation, equipment, or occupancy of adjacent areas.  The licensee shall submit the report of the qualified expert to the agency at the address found in Rule .0111 of this Chapter.

(c)  Except for facilities designed for human exposure, 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 the control panel and other appropriate locations.

(d)  All area monitors shall be tested for proper operation at least every six months unless more frequent checks are required by the agency.

(e)  Whenever applicable, periodic surveys shall be made to determine the amount of airborne particulate radioactivity present in areas of airborne hazards.

(f)  Whenever applicable, periodic smear surveys shall be made to determine the degree of contamination in target and other pertinent areas.

(g)  All area surveys shall be made in accordance with the written procedures established by a qualified expert registered by the agency pursuant to Rule .0205 of this Chapter, or the radiation safety officer of the particle accelerator facility.

(h)  Records of all radiation protection surveys, calibration results, instrumentation tests, and smear results shall be kept current and on file at each accelerator facility for two years for inspection by the agency.
