RADIATION DETECTION DEVICE, RADIATION TESTING SYSTEM, AND METHOD FOR ADJUSTING RADIATION DETECTION DEVICE

摘要

An X-ray detection device 10 is a device that detects X-rays having transmitted through a test subject, and comprises a filter 50 that attenuates some of X-rays, a detector 20 that detects the transmitted X-rays partially attenuated by the filter 50, a housing 30, and a holder 40 that has one slit 42. The detector 20 includes a line sensor 21, and a line sensor 22 disposed in parallel and close to the line sensor 21. The holder 40 holds the filter 50 at a predetermined position so that the filter 50 can cover a part of the slit 42, and the line sensor 22 detects the X-rays attenuated by the filter 50.
