Radioactive wastes generated from nuclear research facilities in Japan Atomic Energy Agency are planning to be buried in the near surface disposal field. Therefore, it is required to establish the method to evaluate the radioactivity concentrations of radioactive wastes until the beginning of disposal. In order to contribute to this work, we collected and analyzed concrete, ash, ceramic and brick samples generated from JRR-3, JRR4 and JRTF facilities. In this report, we summarized the radioactivity concentrations of 24 radionuclides ($^{3}$H, $^{14}$C, $^{36}$Cl, $^{41}$Ca, $^{60}$Co, $^{63}$Ni, $^{90}$Sr, $^{94}$Nb, $^{99}$Tc, $^{\rm 108m}$Ag, $^{129}$I, $^{137}$Cs, $^{133}$Ba, $^{152}$Eu, $^{154}$Eu, $^{\rm 166m}$Ho, $^{234}$U, $^{238}$U, $^{238}$Pu, $^{239}$Pu, $^{240}$Pu, $^{241}$Am, $^{243}$Am, $^{244}$Cm) which were obtained from radiochemical analysis of the samples in fiscal years 2020-2021.
