Tritium is the heavy isotope of hydrogen and can therefore participate directly in a wide range of biological functions. It is formed through natural processes but is also generated through human activity in nuclear reactors, fusion, and weapons. In addition, it has some commercial applications. Its occurrence, chemical and physical properties, and speciation are unique in comparison to other radionuclides. This article summarizes what is currently known about tritium with regard to the isotope's occurrence, chemistry, speciation, remediation, separation, and the analytical techniques used for its detection and quantification. The potential impact of tritium on human health is also described.
