| 摘 要： | 本文用生物样品与有机溶剂共沸蒸馏分离法对秦山核电厂附近秦山上松针中组织自由水氚进行测量。选择甲苯为共沸蒸馏溶剂。松针与甲苯共沸蒸馏,组织自由水回收率达90%。结果表明,松针中组织自由水氚浓度为1.8 Bq/L,与同期大气中氚化水蒸气(HTO)的浓度在同一水平。

| Abstract: | Tissue Free Water(TFW)of pine needles is separated out through azeotropic dis-tillation of pine needles and toluene,Recovery ratio of TFW is 90%.Tritium activity in tis-sue free water of pine needles is 1.8 Bq/L(H_2O),which is of the same level with tritiatedwater vapour(HTO)in atmosphere during the corresponding period. |
