A radioactive tracer, also called a radioactive label, is a substance containing a radioisotope. Tracers can be used to measure the speed of chemical processes and to track the movement of a substance through a natural system such as a cell or a tissue.[1] Radioactive tracing was developed by George de Hevesy.
In medicine tracers are applied in autoradiography and nuclear medicine, including single photon emission computed tomography (SPECT), and positron emission tomography.
