236U是235U在反应堆中俘获中子生成的,是人工放射性核素。环境样品中存在236U可证明有处理辐照铀活动的存在。因此,准确测定环境样品中的236U/238U原子比对于核保障具有重要意义。
236U is 235U capture neutron generated in the reactor, is an artificial radionuclide. The presence of 236 U in environmental samples proves the presence of irradiated uranium. Therefore, accurate determination of 236U / 238U atomic ratio in environmental samples is of great significance for nuclear safeguards.
