Abstract: Three or more tubular radiation detectors are arranged around an irradiation axis of radiation directed to a sample from an irradiation unit such that the end face thereof is opposed to the position irradiated with radiation. The radiation emitted from the sample enters the radiation detector through an end face and is detected. In the radiation detector, the length in the direction parallel to the straight line which is on the plane orthogonal to the irradiation axis and is perpendicular to the central axis continuously decreases from a position along the central axis to the end face. The size of each radiation detector around the irradiation axis is reduced as it approaches the end face, preventing the radiation detectors from interfering with one another and allowing the radiation detector to be closer to the sample compared to the conventional case. This makes it possible for the radiation detection apparatus to detect radiation from the sample with high efficiency.
