为了适应铀矿普查的需要,研制了一种新型测氡仪器,称为阿尔发测氡仪。本文介绍用此种仪器在已知含铀带和新区取得的试验结果。文中还将阐述试验过程中遇到的问题及其解决的办法。氡气普查氡是找镭的指示元素。过去曾用箔式静电计测氡,后来又采用闪烁室式或电离室爱曼仪 In order to meet the needs of uranium census, a new type of radon measuring instrument has been developed, called Alfa radon measuring instrument. This article describes the test results obtained with this instrument in known uranium bearing zones and new zones. The article will also explain the problems encountered in the process of testing and solutions. Radon survey Radon is to find the element of radium. In the past, foil-based static electricity was used to measure radon, and later flash cells or ionization chambers were used
