Therefore, the radioactive isotope can be present in low concentration and its presence detected by sensitive radiation detectors such as Geiger counters and scintillation counters.George de Hevesy won the 1943 Nobel Prize for Chemistry "for his work on the use of isotopes as tracers in the study of chemical processes".Radioisotopes of hydrogen, carbon, phosphorus, sulfur, and iodine have been used extensively to trace the path of biochemical reactions.A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue, Radioactive tracers form the basis of a variety of imaging systems, such as, PET scans, SPECT scans and technetium scans.An extensive list of radioactive tracers used in hydraulic fracturing can be found below.Tc in autoradiography and nuclear medicine, including single photon emission computed tomography (SPECT), positron emission tomography (PET) and scintigraphy. pylori in the stomach, the patient's breath would contain labeled carbon dioxide.Substances which emits radiation is known as radioactive substances and this property of substances to emit radiation is called as radioactivity.

C decays by beta-decay, with a half-life of 5730 y.

There are two main ways in which radioactive tracers are used The commonly used radioisotopes have short half lives and so do not occur in nature. One of the most important processes is absorption of a neutron by an atomic nucleus, in which the mass number of the element concerned increases by 1 for each neutron absorbed.
