Section 30346.2 - Radiation Detection Instruments(a) 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 Article and by section 30275. To satisfy this requirement, the radiation survey instrument must be capable of measuring 0.1 mR per hour through at least 50 mR per hour.(b) The licensee or registrant shall have available additional calibrated and operable radiation survey instruments with the sensitivity to detect the low radiation and contamination levels that could be encountered if a sealed source ruptured. The licensee may own the instrument or may have a procedure to obtain them quickly from a second party.(c) The licensee or registrant shall have each radiation survey instrument required under subsection (a) above calibrated:(1) At intervals not to exceed six months and after instrument servicing;(2) At two points located approximately 1/3 and 2/3 of full scale on each scale for linear scale instruments, at mid range of each decade and at two points on each decade for logarithmic scale instruments, and at appropriate points for digital instruments; and(3) So that an accuracy within plus or minus 20 percent of the calibration standards can be demonstrated on each scale.(d) The licensee or registrant shall retain calibration records for at least three years after the date of calibration for inspection by the Department.Cal.
