随着核能利用的发展,从核设施或核实验释放的~3H 量不断增加。~3H 又是由宇宙射线作用形成的天然核素。~3H 大多以水的形式存在于环境中,因此示踪研究~3H 在水循环中的移动情况能有效地调查水的运动。近年来,利用大规模核实验所产生的~3H 研究水的循环已获得明显效果。其中,IAEA-WMO(世界气象组织)通过全球性观察网对降水中~3H 资料的收集和 Schell 等的分析,在太平洋和大西洋上广泛进行的~3H 浓度的调查及 stlund 等所作的
With the development of the utilization of nuclear energy, the amount of ~ 3H released from nuclear facilities or nuclear experiments continues to increase. ~ 3H is a natural radionuclide formed by cosmic rays. ~ 3H mostly in the form of water in the environment, so tracing ~ 3H movement in the water cycle can effectively investigate the water movement. In recent years, the use of large-scale nuclear test generated ~ 3H study of water circulation has been significantly effective. Among them, IAEA-WMO (World Meteorological Organization) through the Global Observatory on the collection of ~ 3H data precipitation and Schell analysis of the Pacific and the Atlantic over the ~ 3H concentration survey and stlund, etc. made
