PPT-INTERACTION OF X-RAYS WITH MATTER

Properties of X rays Travel in straight line Undergo reflection follow laws of reflection Undergo refraction follow laws of refraction Ionize the gas medium through which they pass INTERACTIONS. Wavelength the size of an atom. Frequencies above UV. Uses of X-rays. Used in airports to examine luggage for the presence of dangerous weapons or bombs or for illegal transit of goods. . used to detect structural deficits or cracks in metal objects such as bridges and aircraft that are likely to be missed by the human eye.
