A radioactive isotope of hydrogen with a mass number of 3. Although small amounts of tritium occur naturally, most tritium is prepared synthetically. It was used in the mid-20th century for luminous dials on watches, clocks, and instruments. It is still used as a tracer in biochemical research, as a gas in some neon-type signs, and as a starting compnent in hydrogen bombs.
