摘要
^(218)Po 快速测氡仪是通过收集、测量氡子体中的一个短寿命子体^(218)Po 核素衰变时辐射出 a 射线的强度来显示氡气场的分布规律．仪器采用高效接收、光电转换、多极倍增、放大方法实现了对 a 射线的采集．通过后期处理、计算，间接测量和了解氡的存在与分布情况．
(218)~Po rapid emanometer type can be used to reveal the radon gas distribution regularity by gathering andmeasuring the intensity of α ray radiated from a short life daughter (218)~Po nuclide of the radon daughter when the nu-clide is decaying.The instrument can be used to collect of α ray by the methods of high efficiency receiving,photovol-taic conversion,multipolar multiplication and amplification.The existence and distribution regularities have beenmeasured indirectly by late processing and computing.
