Abstract: A radiation measurement apparatus 10 includes a visible image acquisition unit 11 that takes a visible image, a radiation intensity acquisition unit 12 that measures intensity distribution of radiation incoming from a direction being substantially equal to an image picking up direction of the visible image acquisition unit, and an intensity display unit 15A that displays an image acquired by overlaying the intensity distribution of radiation, which is represented by using a plurality of colors being allocated to the intensity distribution of radiation on the visible image.

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 image, a counting unit that calculates the number of the alpha ray based on a result of counting the photon derived from the light emission of gas excited by the alpha ray, and is possible to sufficiently eliminate background light (noise light) even if background light is strong, and therefore observe weak light emission.

Abstract: A two-dimensional radiation display device includes: a data acquisition unit that acquires two-dimensional radiation data detected a plurality of times from a plurality of radiation detectors; a data division processing unit that divides the two-dimensional radiation data into data regions of each section of specified direction; an integration processing unit that integrates the two-dimensional radiation data that is detected a plurality of times, for each section of specified direction; a data synthesis processing unit that synthesizes the integration values integrated for each section of specified direction into two-dimensional data including radiation distribution; and an image output unit that outputs two-dimensional data indicating radiation distribution as display data in accordance with a prescribed display format.

Abstract: A radiation detection apparatus is provided with a detection element group which includes a plurality of detection elements arranged on a support substrate, a shield body of which a pinhole is formed on front surface and a slit is formed on back surface, the shield body putting the detection element group therein, a signal processing substrate which processes a detection signal respectively detected by each detection element, is provided outside of the shield body, and has a dimension being larger than a width of the slit, and a relay substrate which goes through the slit and connects each detection element with the signal processing substrate.

Abstract: A radiation measurement apparatus includes a radiation sensor that generates a detection signal, a first counter unit that counts the number of the detection signal, an oscillator that generates periodic signal with predetermined period, an AND circuit that outputs logical product obtained by performing AND operation between the detection signal and the periodic signal, a second counter unit that counts the number of a signal output from the AND circuit, and a display unit that displays a value counted by the first counter unit when a value counted by the second counter unit is less than predetermined value and a value being different from the value counted by the first counter unit when the value counted by the second counter unit is not less than predetermined value.
