tritium
Radioactive hydrogen variant
Tritium is a radioactive isotope of hydrogen with two neutrons instead of none.
It occurs naturally in trace amounts but is produced artificially for use in nuclear weapons, fusion research, and self-luminous devices like watch dials and exit signs.
Tritium's half-life of about twelve years makes it useful for applications requiring steady, low-level radiation.
