2011年,分丰水期和枯水期2次对粤北3个铀矿山所在地区环境水体进行了天然铀、天然钍、226Ra等放射性核素水平的调查测量。饮用水（非受纳水体）采样点11个,样品22个;溪水（受纳水体）采样点10个,样品20个。调查结果表明,饮用水（山泉水）中天然铀、天然钍和226Ra的平均浓度分别为0.74μg/L、0.53μg/L和17.0 mBq/L;溪水中分别为23.4μg/L、0.43μg/L和25.0 mBq/L。
2011년,분봉수기화고수기2차대월북3개유광산소재지구배경수체진행료천연유、천연토、226Ra등방사성핵소수평적조사측량。음용수（비수납수체）채양점11개,양품22개;계수（수납수체）채양점10개,양품20개。조사결과표명,음용수（산천수）중천연유、천연토화226Ra적평균농도분별위0.74μg/L、0.53μg/L화17.0 mBq/L;계수중분별위23.4μg/L、0.43μg/L화25.0 mBq/L。
Naturally occurring radionuclides,such as U,Th,226Ra,in environmental water from three uranium mining areas of northern Guangdong were measured,respectively,using samples taken in wet and dry seasons in 2011.22 drinking water samples（non receiving water） from 11 sampling points,and 20 creek water samples（receiving water） from 10 sampling points were collected.The results shows that the concentrations of U,Th and 226Ra in drinking water（mineral water） are,on average,0.74 μg/L,0.53 μg/L and 17.0 mBq/L,respectively;the concentrations of U,Th and 226Ra in creek water are,on average,23.4 μg/L,0.43 μg/L and 25.0 mBq/L.
