141La was separated and purified from fission products in this work for physical measurements aimed at improving the accuracy of its decay parameters.As the impact of 142La and other fission products,cesium(141Cs,142Cs included)was rapid separated from the fission products,141Cs and 142Ba separation was prepared after a cooling time about 25 s when 142Cs decays to daughter 142Ba,141La purification then
141La was separated and purified from fission products in this work for physical measurements aimed at improving the accuracy of its decay parameters. A the impact of 142La and other fission products, cesium (141Cs, 142Cs included) was rapid separated from the fission products, 141Cs and 142Ba separated was prepared after a cooling time about 25 s when 142Cs decays to daughter 142Ba, 141La purification then

在谈核色变的现实语境中，人们对核废料唯恐避之不及。但是在瑞典，一个名叫奥萨马尔的小镇，已经成功申请成为世界上第一个永久核废料储存库。如果这一计划顺利实施，那么从2020年开始，储存库将正式运营。让人意想不到的是，民调显示，当地的民众非常支持这一做法。 是什么力量让瑞典小镇的居民选择了与核废料共居？ 首先，很多瑞典人一直在向人们解释，核废料并非像人们想象中那么可怕。在宣传大军中，有一位名叫恩斯特
