Applications of Radioactive Isotopes

The aim of this lecture is to present on Applications of Radioactive Isotopes. A radioactive tracer is a very small amount of radioactive isotope added to a chemical, biological, or physical system to study the system. A series of experiments using tracers was carried out in the 1950s by Melvin Calvin at the University of California at Berkley, to discover the mechanism of photosynthesis in plants.
