| 摘 要： | 目的 研究20世纪90年代初我国自来水氚浓度的水平、分布和变化。方法 采集24个省市自治区的442个代表性自来水样品,经电解浓缩等预处理后用低本底液体闪烁谱仪测量水氚,用MS Office建立氚数据库和进行数据处理,用趋势拟合分析求解氚浓度的经、纬度和时间变化关系。结果 确定了我国第一个核电站商业运行前自来水氚浓度代表值,给出了其经、纬度和时间变化趋势。结论 自来水氚浓度随纬度和经度呈线性变化,随时间指数变化,20世纪90年代初我国自来水氚浓度呈现随时间缓慢降低趋势。

| Abstract: | Objective To investigate the tritium concentration and variation of tap water in the early 1990s.Methods 442 representative samples of tap water were collected in 24 provinces, for analyzing tritium concentration by standard method.The variation tendencies of tritium concentration with latitude, longitude and time were processed with MS Office software. Results Tritium representative values for tap water are established and their variations are obtained. Conclusions The tritium concentrations of tap water nearly decreased to their bottom in early 1990s, and still decrease with time.The concentrations are changed lineally with latitude and longitude, and exponentially with time. |
