某铀尾矿库周边地区氡调查

Rn survey in the surrounding region of an uranium mill tailing impoundment

采用中国的KF6 0 6氡累积探测器和日本的MK -Ⅱ氡 /气土 累积探测器 ,对某尾矿库周边地区空气中氡浓度范围、氡浓度的方位分布和距离分布等进行了调查。调查历时 1年 ,每个测量点同时采用这两种仪器。

Rn concentrations in air in the surrounding region of a uranium mill tailing impoundment were surveyed. Some results including the range of Rn concentrations, the Rn distribution related to the direction from the Impoundment, and the Rn distribution related to the distance from the impoundment were presented. The survey lasted for 1 year, the Rn monitors called KF606 from China and MK-Ⅱ from Japan were used. Each sample was measured both by KF606 and MK-Ⅱ, therefore a long-term intercomparison between KF606 and MK-Ⅱ was also compared.
