摘　　要：氡室是刻度测氡仪的一种标准装置,还可以用于相关科学实验。氡源的有效源强和氡室的泄漏率是2个非常重要的参数。在分析传统测量方法的基础上,提出了利用静电收集法连续测氡仪快速同步测量氡源的有效源强及氡室泄漏率的新方法。仅仅利用2个较长周期的测量数据就得到了这两个参数,实验证明该方法准确可靠。Radon chamber is a standard equipment to calibrate radon monitor, and can also be used in the rele-vant scientific experiments.There are two important parameters： effective activity of radon source and radon chamber leak rate.Analysis of the traditional measurement method, we propose a novel method for quickly and simultaneously measuring the effective activity of radon source and radon chamber leak rate by the radon monitor based on electrostatic collection method.The two parameters can be obtained by only two measurement values in two long cycles, and the experiment results show that the method is accurate and reliable.
