Section XV-716 - Calibration and Checking of Survey Instruments

A. A licensee shall ensure that the survey instruments used to show compliance with this Chapter have been calibrated before first use, annually, and following repair.

B. To satisfy the requirements of Subsection A of this Section, the licensee shall:

1. calibrate all required scale readings up to 1,000 milliroentgens (10 mSv) per hour with a radiation source;

2. for each scale that shall be calibrated, calibrate two readings separated by at least 50 percent of the scale rating; and

3. conspicuously note on the instrument the apparent dose rate from a dedicated check source as determined at the time of calibration, and the date of calibration.

C. To satisfy the requirements of Subsection B of this Section, the licensee shall consider a point as calibrated if the indicated exposure rate differs from the calculated exposure rate by not more than 20 percent, and shall conspicuously attach a correction chart or graph to the instrument. A licensee may not use survey instruments if the difference between the indicated exposure rate and the calculated exposure rate is more than the allowed 20 percent.

D. A licensee shall check each survey instrument for proper operation with the dedicated check source before each use. The licensee is not required to keep records of these checks.

E. The licensee shall retain a record of each calibration required in Subsection A of this Section for two years. The record shall include:

1. a description of the calibration procedure; and

2. a description of the source used and the certified dose rates from the source, and the rates indicated by the instrument being calibrated, the correction factors deduced from the calibration data, the signature of the individual who performed the calibration, and the date of calibration.

F. To meet the requirements of Subsections A, B, and C of this Section, the licensee may obtain the services of individuals licensed by the department, the U.S. Nuclear Regulatory Commission, an agreement state, or a licensing state to perform calibrations of survey instruments. Records of calibrations that contain information required by Subsection E of this Section shall be maintained by the licensee.
