本文介绍了用几种核物理探测方法,测定用堆照钚靶制备的~(243)Am产品及其杂质核素的含量,也对进堆前的钚料液和极低含量的杂质,特别是~(241)Am进行了测定,测出了存在于~(238)Pu中α放射性约为10~(-6)的~(241)Am的相对含量。文中描述了探测方法及定性定量结果。
This paper describes the determination of the content of ~ (243) Am produced by the plutonium target and its impurity nuclides using several nuclear physical detection methods. It also analyzes the pre-heap plutonium solution and very low levels of impurities, in particular The relative content of ~ (241) Am in α ~ (238) Pu was about ~ (241) Am. The paper describes the detection methods and qualitative and quantitative results.
