Section 6 CCR 1007-1-9.10 - Radiation Monitoring Requirements
9.10.1 There shall be available at each particle accelerator facility appropriate portable monitoring equipment which is operable and has been appropriately calibrated for the radiations being produced at the facility.
9.10.1.1 Such equipment shall be tested for proper functioning prior to each day of accelerator operation and calibrated at intervals not to exceed one year and after each servicing and repair.
9.10.2 A radiation protection survey shall be performed and documented by a qualified expert, acceptable to the Department, when changes have been made in shielding, operation, equipment, or occupancy of adjacent areas.
9.10.2.1 A registrant shall maintain a record of the radiation measurements made following installation of the accelerator for the duration of the registration and when subsequent changes occur that could potentially affect the radiation levels in adjacent areas.
9.10.2.2 The record required by 9.10.2.1 shall include:
(1) The date of the measurements;
(2) The manufacturer's name, model number and serial number of the accelerator;
(3) A description of the accelerator configuration including whether there were any test objects in the accelerator beam;
(4) The instrument used to measure radiation levels;
(5) A plan of the areas surrounding the accelerator that were surveyed;
(6) The measured dose rate at several points in each area expressed in microsievert (millirem) per hour;
(7) The calculated maximum level of radiation over a period of one week for each restricted and unrestricted area; and
(8) The signature of the Radiation Safety Officer.
9.10.3 The radiation levels in all high radiation areas not in the exposure room shall be continuously monitored.
9.10.3.1 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.
9.10.4 All area monitors shall be calibrated at intervals not to exceed one year and after each servicing and repair.
9.10.5 Whenever applicable, periodic surveys shall be made to determine the amount of airborne particulate radioactivity present.
9.10.6 All surveys shall be made in accordance with the written procedures established by a qualified expert, registered with the Department, or the Radiation Safety Officer.
9.10.7 Records of all radiation protection surveys, calibrations, and instrumentation tests shall be maintained for three (3) years at the accelerator facility for inspection by the Department.
