RADIATION DETECTOR

The radiation detection according to an embodiment of the present invention comprises a plurality of control lines extending in a first direction, a plurality of data lines extending in a second direction orthogonal to the first direction, photoelectric conversion parts provided in each of a plurality of regions demarcated by the plurality of control lines and the plurality of data lines, a plurality of noise detection parts arranged and provided on the outside of the regions in which the plurality of photoelectric conversion parts are provided, a control circuit for inputting a control signal to first thin film transistors respectively provided to the plurality of photoelectric conversion parts and second thin film transistors respectively provided to the plurality of noise detection parts, a signal detection circuit for reading image data signals from the plurality of photoelectric conversion parts and reading noise signals from the plurality of noise detection parts, and an image formation circuit for forming a radiation image on the basis of the read image data signals and the read noise signals. At least any one of the following is the case: the signal detection circuit does not read the image data signals from the photoelectric conversion parts that are adjacent to the noise detection parts, the image formation circuit does not use the image data signals read from the photoelectric conversion parts that are adjacent to the noise detection parts during formation of the radiation image, or the photoelectric conversion parts that are adjacent to the noise detection parts are not electrically connected to at least either the control circuit or the signal detection circuit.
