Section 180-5-008 - RADIATION SURVEY INSTRUMENTS008.01INSTRUMENT PERFORMANCE REQUIREMENTS. The licensee or registrant must keep sufficient calibrated and operable radiation survey instruments at each location where sources of radiation are present to make the radiation surveys required by 180 NAC 4 and 180 NAC 5. Instrumentation required by 180 NAC 5 must be capable of measuring a range from 0.02 millisieverts (2 mrem) per hour through 0.01 sievert (1 rem) per hour.008.02CALIBRATION REQUIREMENTS. The licensee or registrant must have each radiation survey instrument required under 180 NAC 5-008.01 calibrated: (A) At energies appropriate for use and at intervals not to exceed six months or after instrument servicing, except for battery changes;(B) 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 3 points between 0.02 and 10 millisieverts (2 and 1000 mrem) per hour; and(C) So that an accuracy within plus or minus 20% of the true radiation dose rate can be demonstrated at each point checked.008.03RECORDS. The licensee or registrant must maintain records of the results of the instrument calibrations as required by 180 NAC 5-025.180 Neb. Admin. Code, ch. 5, § 008
