64E-5.1103. Radiation Survey Instruments

(1) The licensee or registrant shall maintain sufficient calibrated and operable radiation survey instruments at each field station and temporary jobsite to make physical radiation surveys as required by this part and by Part III. Instrumentation shall be capable of measuring 0.1 milliroentgen (0.001 mSv) per hour through at least 50 milliroentgens (0.5 mSv) per hour.

(2) Radiation survey instruments used to establish dose rates shall be calibrated:

(a) At energies and geometries appropriate for use;

(b) At intervals not to exceed 6 months, and after each instrument servicing;

(c) Such that accuracy within plus or minus 20 percent can be demonstrated; and

(d) 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.

(3) Records of survey instrument calibrations shall be maintained for 3 years after the calibration date for inspection by the Department.
