INTRODUCTION

George de Von Hevesy is the first person to use the radioactive compounds to determine the biological compounds. A radiotracer is defined as the chemical compound which contains the radioactive nuclei as an anion or a cation. The radioactivity is the emission of rays such as α, β and γ-rays. The examples of radionuclide are 3H and 14C which are frequently used for the analysis of the compounds:
