| 摘 要： | 对某矿山工作场所和生活区分别进行了样品采集，并使用ORTEC公司生产的16000道HPGeγ能谱仪进行了测量。结果表明，该矿山工作场所天然放射性核素的比活度大多高于生活区，其中危害最大的为尾矿坝；某些生活区天然放射性核素的比活度比对照点和国家均值要高，但多数都在国家均值范围内，最高值出现在3号生活区的农田土样中，其天然放射性核素的比活度分别为：α（226^Ra）——750．4Bq/kg、α（232^Th）——91．5Bq/kg、α（40^K）——1202Bq/kg。

| Abstract: | This paper describes the May 2007 sampling in the working and living sites of a uranium mine and their measurement with ORTEC 16000 HPGe γ spectrometer. The measured results show that the natural radionuclide specific activity in the workplace is higher than that of the living area, and the greatest dangerous place is the tailings dam. In addition, the natural radionuclide specific activity in some living areas is higher than that of the control point and the national average value. However, the specific activity in most areas is within the national average value. The maximum specific activity occurs in soil samples from the third farmland, and its natural radionuclide specific activities are： α（226^Ra）--750.4 Bq/kg, α（232^Th）--91.5 Bq/kg,α（40^K）--1 202 Bq/kg. |
