Abstract
A radiation detection apparatus includes a selecting unit that allows a light having a light emission wavelength and a polarization direction to pass thorough the selecting unit, an optical system that forms an image of the light, a photon detecting unit that observes the image formed by the optical system, and detects the photon in whole range of the entire image, a counting unit that calculates the number of the alpha rays based on a result of counting the photons derived from the light emission of gas excited by the alpha rays, whereby it is possible to sufficiently eliminate background light (noise light) even if background light is strong, and therefore observe weak light emission.
