In the decommissioning of Fukushima Daiichi Nuclear Power Plant, it is important to specify the distribution and composition of the fuel debris by alpha ray dose analysis. InGaP solar cells is expected to detect alpha-rays because they have the thickness of about one micro meter, which is sufficiently thin with respect to the fly range of alpha-rays. Therefore, the ion irradiation tests with 5 MeV helium was conducted on InGaP solar cells, and the applicability of InGaP solar cells for alpha-ray detector was evaluated and discussed with the results of the experiment and simulation.
