摘　　要：目的调查研究山东省集中式饮用水源地水中总α、总β放射性水平,掌握山东省集中式饮用水源地水放射性水平现状。方法依据《水中总α放射性浓度的测定厚源法》EJ/T 1075-1998《水中总β放射性测定蒸发法》EJ/T 900-94相关方法步骤进行。结果十七个地级市(设区市)以上城市水样34个,其中总α测量值范围为0.010~0.239 Bq/L,总β测量值范围为0.063~0.286 Bq/L。结论山东省集中式饮用水源地水中总α、总β放射性水平满足GB 5749-2006《生活饮用水卫生标准》要求。Objective To investigate and grasp the gross alpha and gross beta activity levels of centralized drinking water sources in Shandong Province.Methods The radioactivities were measured according to the "Determination of gross alpha activity in water thick source method"(EJ/T1075-1998) and "Determination of gross beta activity in water evaporation method"(EJ/T 900-94).Results Thirty-four samples from drinking water sources of seventeen different cities were analysed. The gross alpha activity measurement value range was from 0.010 to 0.239 Bq/L,and the gross beta was from 0.063 to 0.286 Bq/L.Conclusion The gross alpha and gross beta activity levels of centralized drinking water sources in Shandong Province were up to the requirements of "Standards for Drinking Water Quality"(GB 5749-2006).
