摘　　要：简述了125I,139Ce,88Y,57Co,60Co,137Cs和134Cs放射性核素的衰变特性及采用符合法、4πγ电离室法、γ谱仪法、合峰法测量其比活度的测量原理。给出了比活度测量结果,并与中国计量科学研究院的测量结果进行了比较,两者在不确定度范围内有较好的一致性。The decay characterisitic of ~ 125 I,~ 139 Ce,~ 88 Y,~ 57 Co,~ 60 Co,~ 137 Cs and ~ 134 Cs radionuclide and the principle for measurement of specific activity of the seven kinds of nuclide with coincidence method, 4πγ ionization room method, spectroscopy method and summing peak method are simply is described. The results compare with the measurement result from National Institute of Metrology P.R.China, they are agreeable within uncertainty.
