Tritium is a naturally-occurring radioactive isotope of hydrogen that is often used to light up a sign … Web13 de abr. de 2024 · Since the radioactive half-life of tritium is 12.4 years, holding the water in tanks for seven half-lives, about 85 years, would reduce the tritium content to less than 1 per cent of its current value. This option leaves the carbon-14 which would still roughly have the same radioactivity due to its 5,730-year half-life.
