Tritium (3H) is the most stable radioisotope of hydrogen. That is, of all radioactive isotopes of hydrogen, tritium is the least radioactive. It has a proton and 2 neutrons in its nucleus. Tritium decays through beta minus decay and changes to helium-3. It has a half-life of 12.32 years.
Zirconium is radioactive ! Natural zirconium has two radioactive isotopes: 94Zr has a half-life of 1.10Ã1017 years and 96Zr has a half-life of 2.4Ã1019 years. But the specifâ¦ic activity is without health importance, because the half times are very long.
