List two effects of scatter radiation
WebHow ionizations affect cells. Radiation-induced ionizations may act directly on the cellular component molecules or indirectly on water molecules, causing water-derived radicals. Radicals react with nearby molecules in a very short time, resulting in breakage of chemical bonds or oxidation (addition of oxygen atoms) of the affected molecules. WebThe effect of scattered radiation on x-ray image contrast is reviewed. Without scatter control, the information content of x-ray images is severely compromised. Typical grid …
