Radioisotopes and Their Biomedical Applications

Abstract

Radionuclides also termed as radioisotopes are elements that possess radioactivity. It means upon decay they emit radiations like alpha, beta or gamma particles and transformed their nuclei to a stable state. This decaying property of radioisotopes is called half-life. Thus radioisotopes could be used for numerous biomedical purposes such as cancer and tumour treatment, imaging, biochemical assays, biological labelling, sterilization, clinical diagnostics, radioactive dating etc.
