摘要
采用DSA1000γ能谱仪对连云港锦屏磷矿磷尾矿样品中的天然放射性核素比活度进行测量。依据国家标准GB6566-2001,对其进行比较分析,同时采用BH3109A便携式χ、γ剂量率仪巡测整个尾矿坝区的空气吸收剂量率。结果表明,采集的磷尾矿的天然放射性核素水平属于正常水平,其应用不受限制。
The natural radionuclide specific activity of phosphate tailing in Jinping Phosphate Mine, Lianyungang was measured by means of DSA1000γ spectrometer and analyzed according to GB6566 - 2001. The results were confirmed by the measurement of absorbed dose rate in air in the area of phosphate tailing using BH3109A portable X、γ dosage rate instrument. The results showed that the natural radionuclide level in phosphate tailing is within the limit of GB6566- 2001. The phosphate tailing belongs to A type building materials and can be utilized widely without limitation.
