本文介绍一种放化组分离-中子活化分析方法:将活化后的血液样品,相继通过水化五氧化二锑(HAP)柱、阴离子交换柱、阳离子交换柱,把所测核素分成6组,然后用Ge(Li)γ谱仪进行测定。 称取冰干后的血液样品,密封在石英管中(φ6×35mm),与用光谱纯试剂配制的相应标准用铝箔包在一起,密封于照射铝罐中,送入重水反应堆的中心孔道辐照20～40小时,中子通量约为5×10~(13)n·cm~(-2)·s~(-1)。
This article describes a radiochemical separation - neutron activation analysis method: the activated blood samples, successively through the hydration of antimony pentoxide (HAP) column, anion exchange column, cation exchange column, the measured nuclide was divided into 6 Group, and then measured with a Ge (Li) gamma spectrometer. The ice-dried blood samples were weighed, sealed in a quartz tube (φ6 × 35 mm), wrapped with the appropriate standard aluminum foil formulated with a spectroscopic reagent, sealed in an irradiated aluminum can, and fed into a central bore tunnel of a heavy water reactor According to 20 ~ 40 hours, the neutron flux is about 5 × 10 ~ (13) n · cm ~ (-2) · s ~ (-1).
