| 摘 要： | 通过对广州市南沙区主要花岗岩分布区开展土壤中氡浓度调查(网格500m×250m), 发现了多处土壤氡异常区,并对土壤中氡的分布规律进行了讨论。区内土壤中氡浓度的变化范围为0.62~238.61kBq·m-3,本底值为7.957kBq·m-3,异常点最高值是调查区土壤中氡浓度本底值的30倍。

| Abstract: | The concentration of the radon in soil in the main distributing area of granife of Nansha is investigated(500m?250m grid),mang radon unusual district is discovered,and the distributive law of the radon is discussed. The range of concentration of the radon is 0.62~238.61kBq穖-3,the background value is 7.957kBq穖-3.The maximam is 30 time more than the background in the investigating etc. |
