| Abstract: | We have examined the characteristics of solar cells from the standpoint of developing a γ-radiation monitor. This study was performed using a test monitor (TM) manufactured from two monocrystalline-type silicon solar cells coupled to a CsI(Tl) scintillation crystal. The angular and temperature characteristics of current generation were examined using a high-intensity 60Co γ-source. Subsequently, the test monitor was used for checking of transfer operations of spent nuclear fuels. The results obtained by the test monitor utilizing solar cells were better than expected: (a) It is very simple in construction, and (b) it exhibits a good response to high-intensity γ-radiation, and (c) it works without an electric power supply. |
