目前广泛使用的农用稀土产品含有一定量的天然放射性核素。本文用田间小区试验方法,研究喷施稀土溶液后,土壤、冬小麦和菠菜中放射性核素含量的变化情况。结果表明,施用稀土处理组土壤、冬小麦和菠菜中的天然放射性活度与对照组处于同一水平。用水洗方法去掉附着在冬小麦及菠菜植株上的微尘。可以使其α、β及铀的活度降低16%—56%,去污效果十分显著。
Currently widely used agricultural rare earth products contain a certain amount of natural radionuclides. In this paper, field experiments were conducted to study the changes of radionuclide content in soil, winter wheat and spinach after spraying rare earth solution. The results showed that the natural radioactivity in the soil treated with rare earth treatment, winter wheat and spinach was in the same level as that of the control group. Wash with water to remove the dust attached to the winter wheat and spinach plants. Can make its α, β and uranium activity decreased 16% -56%, decontamination effect is very significant.
