| 摘要 |
This nondestructive inspection device (1) comprises an X-ray irradiator (20), a low-energy detector (32), a high-energy detector (42), a low-energy transmittance calculating unit (72), a high-energy transmittance calculating unit (74), a detecting unit (76), and a correcting unit (78). The calculating unit (72) calculates a value indicating the transmittance of transmitted X-rays in a low-energy range. The calculating unit (74) calculates a value indicating the transmittance of transmitted X-rays in a high-energy range. The detecting unit (76) detects details on the positional deviation of the X-ray irradiator (20) on the basis of the ratio between the transmittances calculated by the respective calculating units (72, 74). If the detecting unit (76) detects details on the positional deviation of the X-ray irradiator (20), the correcting unit (78) corrects X-ray luminance data, which have been detected by the detectors (32, 42), in accordance with said details on the positional deviation. |
