Tritium
Tritium
Tritium (pronounced /ˈtrɪtiəm/ or /ˈtrɪʃiəm/) is a radioactive isotope of hydrogen. The term originates from the Greek word "tritos" meaning "third", indicating its atomic number.
Description
Tritium is a hydrogen isotope with two neutrons and one proton. It is radioactive, decaying into helium-3 through beta decay with a half-life of approximately 12.32 years. Tritium is produced naturally in the atmosphere when cosmic rays collide with air molecules. It is also a byproduct in nuclear reactors.
Uses
Tritium is used in research, fusion reactors, and in the self-powered lighting devices known as tritium illumination. It is also used in the production of hydrogen bombs.
Health Effects
Exposure to large amounts of tritium can pose health risks. Tritium can replace regular hydrogen atoms in water to form tritiated water, which can be harmful if ingested or absorbed through the skin.
