Abstract：99Tcm is a short-lived radionuclide and has been widely used in most nuclear medicine.The accuracy of its activity value is very important for applications.Therefore,BIPM organized the international key comparison on the activity of 99Tcm.In March of 2012,the activity measurement of 99Tcm was carried out at the National Institute of Metrology (NIM) in China,with a well-type NaI crystal transfer instrument of the International Reference System (SIRTI) which was set up by BIPM.The stability and reproducibility results show that the status of SIRTI met the requirements of comparison,and the measured equivalent activity of 99Tcm is about 12.580 kBq.
