Abstract
The non-destructive inspection method includes: a water absorbing or drying step of changing a water-content state of a test piece; a transmission image capturing step of irradiating, with a radiation, the test piece absorbed water or dried for a predetermined time in the water absorbing or drying step and capturing a transmission image created by visualizing the radiation transmitted through the test piece; and an evaluation step of evaluating the test piece on the basis of the water-content state of the test piece determined from the transmission image captured in the transmission image capturing step.
Claims16
A non-destructive inspection method comprising:
- a water absorbing or drying step of changing a water-content state of a test piece from a dried state or a water-saturated state;
- a transmission image capturing step of irradiating, with a radiation, the test piece absorbed water or dried for a predetermined time in the water absorbing or drying step and capturing a transmission image created by visualizing the radiation passed through the test piece;
- and
- an evaluation step of evaluating the test piece on the basis of a volume change of the test piece correlating with the water-content state of the test piece determined from the transmission image captured in the transmission image capturing step.
