Explore: Fluorine Radioisotopes

Fluorine-18 (18F, also called radiofluorine) is a fluorine radioisotope which is an important source of positrons. Its half-life is 109.734 minutes, less

than trace quantities; therefore, fluorine is a monoisotopic and a mononuclidic element. The longest-lived radioisotope is 18 F with a half-life of 109

Fluorine is a chemical element; it has symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as pale yellow diatomic

A trace radioisotope is a radioisotope that occurs naturally in trace amounts (i.e. extremely small). Generally speaking, trace radioisotopes have half-lives

decay products of such: As well as being extracted from nuclear waste, radioisotopes can be produced deliberately with nuclear reactors, exploiting the high

only two known synthetic radioisotopes, tennessine-293 and tennessine-294. Approximately six million metric tons of the fluorine mineral fluorite are produced

example, the synthetic fluorine-18 and oxygen-15 are widely used in positron emission tomography. Most synthetic radioisotopes have a short half-life

synthesized via electrophilic fluorination with [18F]F2. Subsequently, a "nucleophilic synthesis" was devised with the same radioisotope. As with all radioactive

Fluorine may interact with biological systems in the form of fluorine-containing compounds. Though elemental fluorine (F2) is very rare in everyday life

device. An example is fludeoxyglucose in which fluorine-18 is incorporated into deoxyglucose. Some radioisotopes (for example gallium-67, gallium-68, and radioiodine)
