Fluorine, a highly reactive nonmetal, has various isotopes that find applications in diverse fields. Fluorine-18 is used in medical imaging, enabling the detection and diagnosis of diseases. In dental health, fluoride strengthens teeth, preventing decay. Fluorine-21 aids in geological dating, determining the age of rocks. Its properties and applications are studied in nuclear chemistry, medical physics, geology, and material science. Organizations like the IAEA, NIST, and ACS are involved in regulating, standardizing, and promoting research on fluorine’s use.
