钚是高毒性的放射性元素,是核设施及周边核环境的放射性污染水平进行监测的重点对象。尤其2011年福岛核事故之后,人们对环境中放射性的监测更加关注。当前,我国面临着大量的核设施退役和核试验场地的安全处理,在此过程中涉及大量样品的放射性分析。由于土壤样品体系复杂,其中钙、镁、铁、钾等常量元素含量较高,同时还存在铀、镭、钍及其衰变子体核素和各种人工放射性核素,给钚的放化分析带来较多困
Plutonium is a highly toxic radioactive element that is the focus of monitoring radioactive contamination of nuclear facilities and the surrounding nuclear environment. Especially after the Fukushima nuclear accident in 2011, people paid more attention to the radioactivity monitoring in the environment. At present, my country faces a large number of safe disposal of nuclear decommissioning and nuclear testing sites, involving radioactive analysis of a large number of samples in the process. Due to the complex soil sample system, the content of Ca, Mg, Fe, K and other elements is high, and there are uranium, radium, thorium and their decaying radionuclides and various artificial radionuclides. The radiochemical analysis of plutonium Bring more sleepy
