Relative Biological Effect (RBE)
{"Image DocumentName": "Relative Biological Effect (RBE)", "Image ImageDescription": "Many scientific investigations have been conducted to study the differing effectiveness of radiations under different experimental conditions. Analysis of the Relative Biological Effectiveness, RBE, is a useful way to compare and contrast the results observed in these studies. The relative biological effectiveness (or dose equivalent) for a given test radiation, is. calculated as the dose of a reference radiation, usually x-rays, required to produce the same biological effect with a dose, DT, of another radiation. Suppose that it takes 200mGy of x-rays but only 20mGy of neutrons to produce the same biological effect, the RBE would be 200/20 = 10 using x-rays as the reference radiation. For radiation protection purposes, the International Commission on Radiological Protection, ICRP, has described the effectiveness of radiations of differing qualities by a series of Quality Factors (ICRP 1977) and more recently by a series of Radiation Weighting Factors (ICRP 1991).", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
