东海海水中3H的测定

~3H(氚)有三个来源:宇宙射线与大气的作用、热核武器的试验、核电站及其它核动力设施的排污。由于达三个来源的累积结果,使北半球的江湖中~3H的浓度高达100—200T.U.(氚单位),雨水的~3H含量高达100—1000T.U.。现在世界各国的核电站与日俱增,估计到本世纪末核电站产生的氚将此现在提高

THE DETERMINATION OF 3H IN THE EAST CHINA SEA

This article is related to the method of analysis of ³H and its distribution in the East China Sea. The seawatcr sample is first distilled to get rid of the salt, then electrolysed to concentrate ³H in the Ni-stainless steel electrolytic cell, finally determined with the liquid scintillation counter. The ³H concentration is greatly varied in the East China Sea, auproachig 30 T. U. off the coast and the mouth of rivers, 10 T. U. in the area farther off the coast, but it is too low to be determined in the deep sea water of 2000 m.
