relative biological effectiveness
relative biological effectivenessn. A measure of the capacity of a specific ionizing radiation to produce a specific biological effect, expressed relative to a reference radiation, such as radium gamma rays or 200-volt x-rays.relative biological effectivenessThe ratio of the number of rads of gamma (or X) radiation of a certain energy that will produce a specified biological effect to the number of rads of another radiation required to produce the same effect measures the "relative biological effectiveness" of the latter radiation.relative biological effectiveness
