摘　　要：以小块铀矿石作为氡气来源,通过连续测量法研究了矿石表面涂刷常规建筑涂料的防氡性能.通过对比涂刷前后封闭氡室的氡浓度,得到多次涂刷后涂料的防氡率.结果表明,封闭氡室的氡浓度随时间的增加而增大,且随着涂刷次数的增加而有所降低.常规建筑涂料的降氡率与涂刷次数呈现正相关性,但其变化幅度并不显著,总体降氡率稳定在38%左右.Using small uranium ore as the source of helium,the anti-radon performance of conventional architectural coatings coated on the surface of ore is studied by continuous measurement.By comparing the concentration of ruthenium in the chamber before and after brushing,the anti-radon rates of the paint after multiple paintings are obtained.Results show that the concentration of sputum in the closed diverticulum increases with time and decreases with the increase of the number of paintings.The anti-radon rate of conventional architectural coatings has a positive correlation with the number of paintings,but the variation range is not significant,and the overall hail reduction rate stayed around 38%.
