Tritium (from Ancient Greek τρίτος (trítos) 'third') or hydrogen-3 (symbol T or 3 H) is a rare and radioactive isotope of hydrogen with a half-life of ~12.3 years. The tritium nucleus (t, sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of the common isotope hydrogen-1 (protium) contains one proton and no neutrons, and that of non-radioactive hydrogen ...
Tritium is only a health threat if ingested or inhaled. Since tritium is a gas, if a tritium tube breaks, the gas dissipates in the air and is diluted to safe concentrations. Tritium has a half-life of 12.32 years, so the brightness of a tritium light source will decline to half its initial value in that time.

Many of the fission products are either non-radioactive or only short-lived radioisotopes, but a considerable number are medium to long-lived radioisotopes such as 90 Sr, 137 Cs, 99 Tc and 129 I. Research has been conducted by several different countries into segregating the rare isotopes in fission waste including the "fission platinoids" (Ru ...
Between 1.5 to 2.1 kilograms (3.3 to 4.6 lb) of tritium were recovered annually at the Darlington separation facility by 2003, of which a minor fraction was sold. [25]: 10 Consequently, the Canadian Nuclear Laboratories in 2024 announced a decades-long program to refurbish existing CANDU plants and equip them with tritium breeding facilities.
As long as it still tastes okay, if you spot some clumps, just shake or tap the package to break things up—and consider refreshing your salt stock in the near future.
However, GTLS contain radioactive tritium gas that has a half-life of slightly over 12.3 years. [13] Additionally, phosphor degradation will cause the brightness of a tritium container to drop by more during that period. The more tritium that is initially inserted in the container, the brighter it is to begin with, and the longer its useful life.
