Radiation detection device

Abstract

The radiation detection device is equipped with a sample holding unit; an irradiation unit for irradiating a sample held on the sample holding unit with radiations; a detection unit for detecting the radiations generated from the sample; an illumination unit for irradiating the sample with light; an observation unit for observing the sample; and a light transmitting plate for allowing the light from the illumination unit, with which the sample held on the sample holding unit is irradiated, to be transmitted therethrough. The light transmitting plate is disposed at a position between the sample holding unit and the irradiation unit, and has an opening portion for allowing the radiations from the irradiation unit, with which the sample is irradiated, to pass therethrough and a scattering portion for scattering light.
