摘要
为了监测郑州市区表层土壤放射性污染情况,本文用高纯锗谱仪对郑州市近郊土壤和尘埃样品进行了放射性测量,确定了^(40)K、^(226)Ra、^(234)Th、^(214)Pb、^(228)Ac和^(106)Ru 等10多种放射性核素、其主要成分是天然放射性核素,也不排除少量的人工放射性核素。
In order to monitor the radioactive pollution of the surface layer soils of Zhengzhou City,the radioactivity of the soils and dust samples of the outskirts of Zhengzhou city are measured by high purity Ge deterctor.More than ten radioactive nuclides,such as K,^(226)Ra,^(234)Th,^(214)Pb,^(228) Ac,^(106)Ru and so on,are determined.They are nature radioactive nuclides primarily,but don't re- move a little induced radioactive nuclides.
