WebIts isotope tellurium-128 has a half-life of 2.2 x (10 to the power of 24) years, which is around 160 trillion times the age of the Universe. It decays via double beta decay, in which a pair of protons change into neutrons or vice versa. ... The previous record holder, bismuth-209, still has the longest half-life via alpha decay. All records ... The half-life of bismuth-209 was confirmed in 2012 by an Italian team in Gran Sasso who reported (2.01 ± 0.08) × 10 19 years. They also reported an even longer half-life for alpha decay of bismuth-209 to the first excited state of thallium-205 (at 204 keV), was estimated to be 1.66 × 10 21 years.
