Section 6 CCR 1007-1-16.8 - Radiation survey instruments
16.8.1 The licensee or registrant shall keep a calibrated and operable radiation survey instrument capable of detecting beta and gamma radiation at each field station and temporary jobsite to make the radiation surveys required by this part and by Part 4 of these regulations. To satisfy this requirement, the radiation survey instrument must be capable of measuring 0.001 mSv (0.1 mrem) per hour through at least 0.5 mSv (50 mrem) per hour.
16.8.2 The licensee shall have available additional calibrated and operable radiation detection instruments sensitive enough to detect the low radiation and contamination levels that could be encountered if a sealed source is ruptured. The licensee may own the instruments or may have a procedure to obtain them quickly from a second party.
16.8.3 Each radiation survey instrument shall be calibrated:
16.8.3.1 At intervals not to exceed 6 months and after each instrument servicing;
16.8.3.2 For linear scale instruments, at two points located approximately 1/3 and 2/3 of full-scale on each scale; for logarithmic scale instruments, at midrange of each decade, and at two points of at least one decade; and for digital instruments, at appropriate points; and
16.8.3.3 So that accuracy within 20 percent of the true radiation level can be demonstrated on each scale.
16.8.4 Calibration records shall be maintained for a period of 3 years after the date of calibration for inspection by the Department.
