X-Ray Interaction With Matter
Chemistry
Energy
Radiation
An X-ray (composed of photons) has a lot of intrinsic energy and when it passes through matter that comes on its path, it would interact with the matter and either by absorbed by the matter (energy gets transferred to the matter) or be redirected in other directions (scattered). Various substances depending on their inherent properties…
