摘要
本文介绍一种用液体闪烁计数器对空气中^(14)C以CaCO_3形式进行固体悬浮测量的方法。文中讨论了甲苯-Triton X-100-水体系作为固体悬浮体的使用条件、样品制备方法以及温度影响等因素,并给出了初步测定结果。
A technique for determining 14C in air by the solid suspension method with liquidscintillation counter is presented. In this paper, conditions of the 'Toluene-Triton Xa100-Water' system as the solid suspension, methods of sample preparation and theeffect of temperature etc., are discussed. The preliminary results of determinations arealso given.
