Section 459.712 - Equipment control: Radiation survey instruments1. The registrant shall maintain sufficient calibrated and operable radiation survey instruments at each location where radiation producing equipment is used. Instrumentation required by this section must have a range such that 2 millirems (0.02 millisievert) per hour through 1 rem (0.01 sievert) per hour can be measured.2. Each radiation survey instrument must be calibrated:(a) Against appropriate energy at intervals not exceeding 6 months and, except for battery changes, after each servicing of the instrument;(b) So that accuracy within plus or minus 20 percent can be demonstrated at each point checked; and(c) At two or more widely separated points, other than zero, on each scale, as follows: (1) For linear scale instruments, at two points located approximately one-third and two-thirds of full scale on each scale;(2) For logarithmic scale instruments, at the mid-range of each decade and at two points of at least one decade; and(3) For digital instruments, at 3 points between 2 millirems (0.02 millisievert) per hour and 1 rem (0.01 sievert) per hour.3. Records of these calibrations must be maintained for at least 3 years after the calibration date for inspection by the Division.Nev. Admin. Code § 459.712
