在132I的核数据衰变测量中,需要得到放化纯的132I的溶液。132I的分离提取有直接法和间接法两种。直接法是从辐照后的235U混合裂变产物中直接进行分离,但得到的132I溶液中有131I(T1/2=8.04 d)、133I(T1/2=21 h)、135I(T1/2=6.7 h)存在,影响数据的测量;间接法则根据其前驱核相对
In the 132I nuclear data decay measurement, it is necessary to obtain a solution of radiochemically pure 132I. 132I separation and extraction methods are direct and indirect two. The direct method was separated directly from the 235U mixed fission product after irradiation, but 131I (T1 / 2 = 8.04 d), 133I (T1 / 2 = 21 h), 135I (T1 / 2 = 6.7 h) exists, affecting the measurement of data; the indirect rule is based on its precursor nucleus relative
