Current through Register Vol. 50, No. 9, September 20, 2024

A. The licensee or registrant shall maintain sufficient calibrated and operable radiation survey instruments at each location where radioactive material is present to make physical radiation surveys as required by this Chapter and LAC 33:XV.430. Instrumentation required by this Section shall have a range such that 0.02 millisieverts (2 millirems) per hour through 0.01 sievert (1 rem) per hour can be measured.

B. Each radiation survey instrument shall be calibrated:

1. at energies appropriate for use and at intervals not to exceed six months and after each instrument servicing;

2. such that accuracy within +20 percent can be demonstrated; and

3. at two points located approximately 1/3 and 2/3 of full-scale on each scale for linear scale instruments; at midrange of each decade, and at two points of at least one decade for logarithmic scale instruments; and at three points between 0.02 and 10 millisieverts (2 and 1000 millirems) per hour for digital instruments.

C. Records of these calibrations shall be maintained for three years after the calibration date for inspection by the department.

D. Each radiation survey instrument shall be checked with a radiation source at the beginning of each day of use and at the beginning of each work shift to ensure it is operating properly. Records of the checks shall be maintained for three years. If equipment problems are found, the equipment must be removed from service until repaired.
