摘　　要：采用半导体探测器,利用核谱测量技术与嵌入式技术研制的新型测氡仪-α谱仪。可以很好的解决连续测氡与瞬时测氡以及α谱测量的要求。利用静电收集氡衰变子体进行测量,灵敏度高,现场获取结果,体积小,操作方便。可用于室内测氡、壤中测氡、水溶液测氡以及钍射气测量等领域。Applying semi-conductor detector, nuclear spectrum technology and embed system technology the new type detecting system in made. This system can detect radon in short time and in long term and can be used to get α-particle spectrum. It uses the static electric field to gather the electric daughter product of radon. Then it has high sensltivity. This system is tiny and can be easily operated . And the result is given in field . It can be used to measure radon in air, water and soil and thorium emanation （^220Rn）.
