Health Physics Questions and Answers - Question 209

Question 209:

(a) Does the revised Part 20 require that meters be calibrated?

(b) If so, is the calibration frequency specified?

Answer:

(a) Yes, 10 CFR 20.1501 (b) requires that the licensee insure that instruments and equipment used for quantitative radiation measurements are calibrated periodically for the radiation measured.

(b) Part 20 regulations do not define "periodically." However, specific NRC license conditions and other Parts of Title 10 (i.e., Parts 34 and 35) may specify the periodicity for calibration.

(Reference: 10 CFR 20.1501)
