放射性同位素的广泛应用与发展,接触放射性的人越来越多,加之核电站的发展,放射性对环境的污染有可能发生,特别是苏联切尔诺贝利核电站事故,已对东欧各国造成了严重影响,一些核国家核潜艇中的核泄漏也不时发生,诸如此等,核安全已变成一个问题。据报道目前世界上每年约有数十万人死于放射性导致的癌症。因此,射线探测与报警对人类生命安全实为重要。目前世界各国都在开发这类产品。从当前看,现有产 The widespread application and development of radioisotopes and the increasing exposure of radioactive sources, together with the development of nuclear power stations, may cause environmental pollution by radioactivity. In particular, the accident at the Chernobyl nuclear power plant in the Soviet Union has caused serious disruption to the countries of Eastern Europe Nuclear leaks in nuclear submarines in some nuclear countries have also taken place from time to time. And so on, nuclear safety has become a problem. It is reported that there are currently about hundreds of thousands of people in the world each year due to radioactive cancer. Therefore, ray detection and alarm on human life and safety is really important. At present, all countries in the world are developing such products. From the current perspective, the existing production
