In the future, radioactive wastes which generated from research and testing reactors in Japan Atomic Energy Agency are planning to be buried for the near surface disposal. Therefore, it is required to establish the method to evaluate the radioactivity concentrations of radioactive wastes by the time it starts disposal. In order to contribute to this work, we collected and analyzed the samples generated from JRR-2, JRR-3 and Hot laboratory facilities. In this report, we summarized the radioactivity concentrations of 25 radionuclides ($^{3}$H, $^{14}$C, $^{36}$Cl, $^{60}$Co, $^{63}$Ni, $^{90}$Sr, $^{94}$Nb, $^{93}$Mo, $^{99}$Tc, $^{108m}$Ag, $^{126}$Sn, $^{129}$I, $^{137}$Cs, $^{152}$Eu, $^{154}$Eu, $^{233}$U, $^{234}$U, $^{238}$U, $^{238}$Pu, $^{239}$Pu, $^{240}$Pu, $^{241}$Pu, $^{241}$Am, $^{243}$Am, $^{244}$Cm) which were obtained from radiochemical analysis of those samples.
