摘　　要：本文综合报道了７个不同地区自来水制水过程对源水中放射性核素的净化率（％）范围；总α放射性１２～５１，总β放射性８～７６，天然铀１０～５６，天然钍３６～７９，镭２２６２６～６３，锶９０１３～３７，铯１３７１２～５４。The range of radioactive nuclides purifying rate(%)during tap water processing from natural freshwater in seven different areas in China. The radionuclides purifying rates for gross α-activity,gross β-activity,natural uranium, natural thorium,radium 226,strontium 90 and Cesium 137 were in range of 12%～51%, 8%～76%, 10%～56%, 36%～79%, 26%～63%, 13%～37% and 12%～54%, respectively. The reason for the different purifying rates in those 7 areas was discussed.
