摘要: 通过开展相关实验和理论分析工作,对氚在干旱地区非饱和土壤中的时空分布、迁移距离、迁移速率等迁移特征参数及其影响因素进行研究,并对氚在土壤中迁移的机理进行初步分析,得到氚在干旱地区非饱和土壤中的迁移速率为向上3.33 cm/d,向下0.033~0.067 cm/d,横向迁移速率为2 cm/d。氚在土壤中的迁移速率明显受地表蒸发和降雨的影响。

Abstract: Based on the related experiments and mechanism analysis, the characteristic parameters of tritium migration in unsaturated soil of arid region have been studied including spatial and temporal distribution, migration distance, migration velocity as well as their influence factors. And the migration mechanism also has been preliminary analyzed. The upward and downward migration velocities of tritium in soil of arid region are 3.33 cm/d and 0.033—0.067 cm/d respectively, and the transverse migration velocity of tritium is 2 cm/d. The migration velocity of tritium in soil is significantly affected by the evaporation and rainfall.

Key words: tritium, radionuclide migration, arid region, unsaturated soil, migration velocity
