Current through Register Vol. 30, No. 38, September 20, 2024

A. A registrant shall maintain at least two calibrated and operable radiation survey instruments at each location where sources of radiation are present to make radiation surveys required by this Article and Article 4 of this Chapter. Instrumentation required by this Section shall be capable of measuring a range from 0.02 millisieverts (2 millirems) per hour through 0.01 sievert (1 rem) per hour.

B. A registrant shall ensure that each radiation survey instrument required under subsection (A) is calibrated:

1. At intervals that do not exceed six months, and after instrument servicing, except for battery changes;

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 0.02 and 10 millisieverts (2 and 1000 millirems) per hour; and

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

C. A registrant shall make a record each time a radiation survey instrument is calibrated, and maintain each record for three years after it is made.
