我院水文系同位素实验室使用国产2101型液体闪烁计数仪完成了对天然水中氚的测定流程,现巳正式投入生产,欢迎各单位送样。为了适应氚的低本底测定,他们采用了增加内外铅屏蔽、更换光导、选用聚四氟乙烯计数瓶和使用曲拉通——甲 Laboratory isotopes of hydrology department of our hospital using domestic 2101-type liquid scintillation counter to complete the determination of tritium in natural water, it has been formally put into production, are welcome to send samples. In order to adapt to the low background determination of tritium, they used an increase of internal and external lead shielding, replace the light guide, the selection of polytetrafluoroethylene counting bottles and the use of Triton - A
