Section 61-63.V.RHA 5.8 - Radiation Survey Instruments

5.8.1 The licensee shall keep sufficient calibrated and operable radiation survey instruments at each location where radioactive material is present to make the radiation surveys required by this part and by Part III. Instrumentation required by this section must be capable of measuring a range from 2 millirems (0.02 millisieverts) per hour through 1 rem (0.01 sievert) per hour.

5.8.2 The licensee shall have each radiation survey instrument required under RHA 5.8.1 calibrated:

5.8.2.1 At intervals not to exceed 6 months and after instrument servicing, except for battery changes;

5.8.2.2 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 3 points between 2 and 1000 millirems (0.02 and 10 millisieverts) per hour; and

5.8.2.3 So that an accuracy within plus or minus 20 percent of the calibration source can be demonstrated at each point checked.

5.8.3 Each licensee shall maintain records of the calibrations of its radiation survey instruments and retain each record for 3 years after it is made.
