    • Abstract
  • A home intercomparison of emission rate measurements by means of Ge(Li)detector and ~(152)Eu source was organized by National Institute of Metrology (NIM).~(152)Eu standard source was used for the efficiency calibration of 130 cm~3 Ge(Li)detector. The emission rate of gamma rays of ~(22)Na (1274.5 keV), ~(54)Mn (834.85keV),~(57)Co (122.06 keV), ~(60)Co (1173.22 keV, 1332 keV), ~(134)Cs (604. 66 keV, 795.76keV), ~(137)Cs (661.65 keV) and ~(133)Ba (356.04 keV) were measured with estimatederrors less than 2%. Our results are compared with results of center of EnglishRadiochemistry as well as those of NIM.
