Management of radioactive wastes is one of the main issues of nuclear power technology. Radioactive wastes can be regarded as energy resources because of their stable radioactive emissions for long half-lives. In this study, we have attempted a direct conversion from gamma rays to electricity using solid state materials such as III-V semiconductors. The experiments were done using the gamma rays of 660keV ( $^{137}$ Cs), 60 keV ( $^{241}$ Am), 30 keV ( $^{237}$ Np). The energy conversion efficiencies were 0.1-1%. Details will be reported at the conference.
