Scatter radiation, as described in Chapter 3, is primarily the result of the Compton interaction, in which the incoming x-ray photon loses energy and changes direction. Two major factors affect the amount and energy of scatter radiation exiting the patient: kilovoltage peak (kVp) and the volume of tissue irradiated. ram shower

WebEvery material has a "halving thickness." This is the thickness required to reduce the radiation intensity by half. So if the halving thickness of a material is 1 inch, then a 1 inch thick sheet will cut the radiation to 50%. Two inches will cut the radiation to 25%, 3 inches to 12.5%, and so forth.
