Calculation of stopping powers for positrons through matter

In this work, the stopping power of the positron in Al, Si, Ag, Cu, and Pb elements were determined by using different methods. It is difficult to obtain the exact result of stopping power for the positrons. Hence many attempts have been done by the researchers to obtain empirical formulations to estimate the stopping powers of the positron in the elements. It was found that each method provides a proper result depending on the the energy range of the positron.Stopping power of the positron have a wide application in radiation dosimetry.. The knowledge of the ranges and stopping powers of this particle in matter has useful applications for the study of biological effects, radiation damage dosoge-rates and energy dissipation at various depths of an absorber. It has also useful applications in the design of detection systems, radiation technology, semi-conductor detectors, shielding and choosing the proper thickness of the target.
