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

A. A licensee shall maintain at each field station and temporary job site a calibrated and operable radiation survey instrument capable of detecting beta and gamma radiation. The licensee shall ensure that the radiation survey instrument is capable of measuring 1.0 microsievert (0.1 millirem) per hour through 500 microsievert (50 millirem) per hour.

B. A licensee shall ensure that additional calibrated and operable radiation detection instruments are available as needed and that the instruments are sensitive enough to detect the low radiation and contamination levels that could be encountered if a sealed source is ruptured.

C. A licensee shall ensure that the radiation survey instrument required in subsection (A) is calibrated

1. At intervals not to exceed six months and after each instrument servicing;

2. At energies comparable to the energies of the radiation sources used;

3. For linear scale instruments, at two points located approximately 1/3 and 2/3 of full-scale on each scale or for logarithmic scale instruments, at mid-range of each decade, and at two points of at least one decade; and

4. So that accuracy within plus or minus 20 percent of the true radiation level can be demonstrated on each scale.

D. A licensee shall retain calibration records for a period of three years from the date of calibration.
