1. (a) Each user shall maintain a sufficient number of calibrated and operable radiation survey instruments to make radiation surveys as required by this regulation. Each instrument shall be capable of measuring a range of two millirems per hour through one rem per hour.

2. (b) Each radiation survey instrument shall be calibrated:

   1. (1) At intervals not to exceed six months and after each instrument servicing;
   2. (2) For linear scale instruments, at two points located approximately one-third and two-thirds of full-scale on each scale; for logarithmic scale instruments, at mid-range of each decade, and at two points of at least one decade; and for digital instruments at three points between two and 1000 millirems per hour; and
   3. (3) So that an accuracy within plus or minus 20 percent of the calibration source can be demonstrated at each point checked.
3. (c) Records of the results of instrument calibrations shall be maintained for three years and kept available for inspection.
