摘　　要：以１３３Ｂａ和１３７Ｃｓ的混合物模拟１３１Ｉ的γ谱，系统地研究了１３３Ｂａ和１３７Ｃｓ的适宜配比、源的结构与组成、支持体制备、吸收材料及其厚度的确定等，建立了制备模拟１３１Ｉ标准源的方法，得到了长寿命模拟１３１Ｉ标准源，并讨论了应用模拟１３１Ｉ吨标准源的方法。method for preparing simulated 131I standard source with mixed 133Ba and 137Cs is presented. Aseries of experimental conditions are investigated such as the choice of the optimum ratio of t33fo to]abCs, the structure and compoSition of simulated 131I standard source, the determination of the support, absorb material and its thickness and so on. The procedure for prefering simulated 131I standard sourceis set up. TeSt resultS show that the simulated 13]l standard source obtained by the methed fully meetSthe requirements of the radioactive standard.
