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.

What makes gamma-ray observations distinctive?. MVSc. PhD. Interaction with matter. X-rays are actually photons travelling with the speed of light.. Interaction.. How a photon interacts with matter on which it falls/impinges.. Matter may be tissue/cells/or non-biological material (here, we are considered with biological material only).. X Rays. Are electromagnetic radiations having wavelength of order of 1. Are highly energetic radiations which are emitted when energetic electrons are made to incident on a metallic target.. Were discovered by German Physicist W.C. Roentgen in1895..
