目前低水平氚测量主要在两个方面发展,其一是降低本底,减少高能辐射和环境辐射本底;其二是对氚浓集。电解水浓集氚是氚浓集的一种重要方法,其原理是氚的结合能略高于氢,准确控制电解电位,降低THO分子与H2O分子被电解的比例。氚水样经过电解后,在剩余水样中,氚浓度被大幅提高。本工作对某单位提供的海水样进行水中氚测量,水样中的氚含量接近本底水平,用对样品进 At present, low-level tritium measurement is mainly developed in two aspects. One is to lower the background, reduce the background of high-energy radiation and environmental radiation, and the other is to concentrate tritium. Electrolyzed water concentration of tritium is an important method of tritium concentration, the principle is that the binding energy of tritium is slightly higher than hydrogen, accurately control the electrolysis potential and reduce the proportion of THO molecules and H2O molecules being electrolyzed. Tritiated water samples After electrolysis, the tritium concentration was significantly increased in the remaining water samples. This work on a unit of seawater samples for water tritium measurement, tritium content in water samples close to the background level, with the sample into
