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
