用罐装氡气校准测氡仪的方法研究

Abstract

Abstract: In order to meet the needs for calibration of radon detector during the verification interval, a method using canned radon was developed. The measurement is based on the principle of measuring radon and the law of radon decay. A dynamic standard material—canned radon was developed, which can effectively overcome the lack and shortcomings of the standard radium source and be used in the quality control of radon detector. The experiment results showed that this method could meet the requirements for radon calibration source in JJG 825—2013 “Verification regulation of radon detector”, confirming that it is feasible to calibrate radon detector using this method.

Key words: radon detector, radon, calibration, canned radon
