A radiation detection device 80 according to an embodiment is a radiation detection device for a foreign substance inspection using a subtraction method, including a first radiation detector 32 and a second radiation detector 42 that detect radiation transmitted through a specimen S, a timing control section 50 that controls detection timings, and an image correction section 34, wherein a first pixel width Wb1 in an orthogonal direction orthogonal to an image detection direction of each pixel of the first radiation detector 32 is smaller than a second pixel width Wb2 in the orthogonal direction of each pixel of the second radiation detector 42, the timing control section 50 synchronizes detection timings of the second radiation detector 42 to detection timings of the first radiation detector 32, and the image correction section 34 sums Wb2/Wb1 pixel data successive in an image from the first radiation detector 32. |
