Performance of -ray spectrum analysis softwares is significantly important because it directly affects the results of nuclide identification and radioactivity measurement. The Expert Committee on Next-generation Gamma-ray Spectrometry, Science and Engineering Committee, Japan Radioisotope Association, performed intercomparison of -ray analysis software by analyzing the same reference spectra with several softwares used in Japan, to know and to improve their performance. It was found that the number of peaks detected by the peak search analysis and deduced peak areas were different among each of the softwares. The reasons why such differences occur are investigated in detail.
