and single photon emitted computed tomography (SPECT) are used for scans by distributing radioactive tracer molecules to produce a 3D image by emitting gamma rays within the body. Since exposure is low and only given in the least amount of radiotracers, it is safe and useful for examinations. A radioisotope used for diagnosis must emit gamma rays of sufficient energy to escape from the body and must have a half-life short enough for it to decay away soon after imaging is completed and doses administered

interactions of the tracers within the body, in the sequence of specific physiological processes. In vitro applications of radioisotopes have become a most important tool in biochemical analysis. Therapeutic uses of radioisotopes cover from external gamma-ray sources in teleradiotherapy to direct cell irradiation in metabolic therapy. Radioisotopes can be use in medicine in four different ways. They are: 1. Radioactive tracers for diagnostic purposes 2. Radiation source in therapy 3. Research and 4
