Fundamentals of radioactivity:

You have studied about the fundamentals of radioactivity, its discovery, how it arises, decay laws and units. Detailed features of natural and artificial radioactivity are discussed along with their four decay series- natural and artificial. A brief account of nuclear reactions was presented in terms of energetics and nuclear reaction cross section which are essential for the production of radioisotopes. Also discussed are the production of radioisotopes and preparation of radiotracers and radiolabelled compounds. Detection and measurement of radioactivity is briefly dealt. Three important methods for the detection and measurement of nuclear radiation based on its energy-gas ionization, scintillation and solid state semiconductor detectors with basics of instrumentation are discussed. Statistical aspects of radioactivity and background correction methods are also discussed.
