We present a relation for continuous slowing down approximation (CSDA) ranges for electrons of substances such as bones, muscles, fat and water in terms of energy from 30 keV to 1000 keV and have been fitted by three parameters. These parameters depend upon the total energy, density and effective atomic number of the absorber. It has been found that this method gives better agreement with the available experimental data.
