| 中文摘要: |
| 天然放射性辐射估算,是环境评价中判定天然放射性辐射水平的一项重要工作。文章介绍了一种矿区天然放射性外照射的估算方法,通过系统地采集矿区地层岩石样品并记录其采样位置,用低本底多道γ能谱仪对样品中的镭-226、钍-232、钾-40放射性比活度进行测量,换算得到外照射空气的吸收率,按采样点位绘制矿区放射性外照射空气的吸收率分布区图,按区估算出矿区及外围天然放射性外照射年有效剂量。 |
| 英文摘要: |
| Estimating the natural radioactive external radiation is an important work to measure the level of natural radiation in the environmental assessment. This article will introduce a method of estimating the external natural radioactive radiation in a Cu-Co deposit in Congo Kinshasa. By systematically collecting rock samples from the strata and recording the sampling position, the specific radio activity of Radium226, thorium232, and potassium 40 are measured using a low background multi-channels gamma-ray spectrometer for each sample, then transformed into external exposure air absorption. According to the sample position, the external exposure air absorption distribution area chart can be rendered and on the basis of the area chart, the annual effective dose of natural radioactive radiation can be finally estimated. |
