| 摘 要： | 采用模拟土柱法研究了95Zr在2种淹水土壤（小粉土、红黄壤）中的淋溶和垂直迁移。结果表明：（1）淋溶后收集到的全部淋溶液中95Zr的含量较少,小粉土淋溶液中95Zr为总活度的3.05%,黄红壤淋溶液中95Zr为总活度的3.00%;（2）滞留于土壤中的95Zr绝大部分分布在土壤表层0～1.0cm范围内,小粉土中有67.80%～80.18%的95Zr滞留于0～1.0cm土层范围内,黄红壤中有74.05%～86.95%的95Zr滞留于0～1.0cm土层范围内;（3）土壤中95Zr比活度与距土壤表层深度分布呈单项指数规律。

| Abstract: | The leaching characteristics and vertical transference of radioactive nuclide zirconium-95 in two representational soils（paddy soil,yellow-red earth）were studied with soil-pole simulation installation.The results showed that：（1）The specific activity of zirconium-95 in collected leachate was low after passing through soil column.The amount of zirconium-95 in leachate of paddy soil was 3.05%,and yellowred earth was 3.00%.（2）In paddy soil and yellow-red earth,67.80%～80.18% and 74.05%～86.95% radioactivity of zirconium-95 was concentrated in the 0～1.0 cm upper layer soils respectively,which illustrated that most of zirconium-95 remained in the surface soils.（3）The specific activity of zirconium-95 in soil present was an individual exponential declining with depth of soil. |
