Characteristics of Imaging Plate to alpha-rays and gamma-rays were studied. Gamma-ray energy dependence of the response of the Imaging Plate was measured by irradiation of gamma-rays with different energy which was emitted from 241Am, 137Cs and 60Co. As a result, the PSL value to one gamma-ray from these nuclides was 3.1x10-3, 3.1x10-4 and 3.6x10-4 respectively. Also, the PSL value per 1 keV absorbed energy in Imaging Plate was 1.4x10-4, 2.3x10-4 and 3.4x10-4 respectively. Possibility of alpha-ray counting by Imaging Plate was examined using alpha-ray emitted from 60Np. As a result, when the incident alpha-ray was perpendicular to Imaging Plate, the number of incident alpha particles could be measured by counting spot images in the picture taken by the Imaging Plate. When the incident alpha-ray was diagonal, the number of incident alpha particles could be estimated by comparing the picture of the sample with the picture of standard alpha-ray source.
