The following points highlight the three main purposes of radioisotopes in medical science. The purposes are: 1. Experimental 2. Diagnostic 3. Therapeutic. Purpose # 1. Experimental: (i) The research work needs radioisotopes to investigate absorption, mobilization, storage, and distribution of different substances in the body. (ii) The substance under investigation is 'tagged' with a radioactive isotope which acts as a [...]
