伴生放射性矿开发利用场址开放土壤残留放射性水平研究

Abstract

Abstract: During the exploitation and utilization of associated radioactive ore, the associated natural radionuclides may migrate to soil and cause soil pollution. This paper analyzes soil pollution risk control regulations in China and internationally. By using RESRAD software program, the screening value of residual soil radioactivity at the open site of associated radioactive ore utilization according to different land use purposes were calculated and deduced. The calculated screening values were compared with those recommended by the U.S. regulatory agency. Therefore, the screening values of soil residual radioactivity of 6 typical radionuclides were determined, which can help improve our country’s soil radioactive pollution risk control regulations.

Key words: associated radioactive ore, natural radioactivity, RESRAD, open site, risk control, screening value
