【摘要】 为了解鉴江放射性含量,分别在鉴江流域布设了5个水质和底泥监测点,取样进行总α和总β分析,并与省内本底调查资料比较,结果表明:鉴江水质中放射性含量上下游都比较低,而底泥的放射性含量则下游略高于上游;鉴江底泥放射性含量也低于省内各地土壤放射性含量的平均值;鉴江水质放射性总α和总β符合生活饮用水卫生标准。更多还原

【Abstract】 In order to investigate the contents of the radioactivity of Jianjiang river,five stations were set up to monitor the water quality and the bed mud according to the controlled principle.General α-analysis and β-analysis were evaluated based on the evaluation standard.By analogizing to the background survey data of other rivers in Guangdong,it was found that both the radioactivity contents in the water of the lower reach and the upper reach are low,but the radioactivity content in the bed mud of the lower reach is less higher than that of the upper reach.It is concluded that the water in Jianjiang river meets the standard of drinking water.Both the radioactivity general αvalue and β-value are lower than the average values of other rivers in Guangdong.The radioactivity content of the bed mud in Jianjiang River is lower than the average value of other cities in Guangdong.更多还原
