摘要/Abstract

摘要： 本文对甘肃省石煤资源的伴生矿物天然放射性核素的活度浓度水平以及开发利用过程中产生的辐射问题进行了调查,石煤伴生矿放射性主要来自铀系核素²³⁸U和²²⁶Ra,部分矿区的²³⁸U和²²⁶Ra的放射性活度浓度的平均水平超过了1 Bq/g。并对甘肃省某石煤提钒企业的测量数据,评估了工作人员以及公众接受的照射剂量率,分析了放射性污染以废水、废气、放射性固体废物等形式向环境转移的可能性。最后对石煤伴生放射性矿现存的各类放射性污染问题提出相应的建议。

关键词: 石煤, 伴生放射性, 照射剂量率, 辐射环境污染

Abstract: In this paper, the geographical distribution of stone coal associated radioactive mineral resources in Gansu Province was introduced, and the natural radionuclides of stone coal associated minerals and radiation problem was studied in the process of development and utilization. Investigations found that the radioactivity of stone coal associated ore mainly comes from uranium series radionuclides ²³⁸U and ²²⁶Ra, and the average activity concentration of ²³⁸U and ²²⁶Ra in some mining areas exceeds 1 Bq/g. Taking a stone coal vanadium extraction enterprise in Gansu Province as an example, the radiation dose rate recieved by the staff and the public is evaluated, and the possibility of radioactive pollution transferring to the environment in the form of waste water, waste gas and radioactive solid waste is analyzed. In view of the existing radioactive pollution problems of stone coal associated radioactive mines, the corresponding suggestions are put forward.

Key words: stone coal, associated radioactivity, irradiation dose rate, environmental radiation pollution
