摘要/Abstract

摘要： 为满足测氡仪校准和检定周期内的期间核查的需要,研制用罐装氡气校准测氡仪的方法。该方法采用氡的衰变规律和氡的测量原理,研制了动态标准物质——罐装氡气,可有效地克服标准镭源的缺乏和缺点,实现测氡仪质量控制活动。实验测试表明,该方法满足《测氡仪检定规程》JJG 825—2013中氡源的要求,用该方法校准测氡仪是可行的。

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
