WebDec 28, 2024 · Last episode, we learned about nuclear isomers, because some people believe hafnium-178m can be weaponized. In stark contrast, tantalum-180m is the most stable stable isomer that can be found in nature. Theoretically it is radioactive, but its half-life is somewhere on the order of one quadrillion years. WebA total of 38 radioactive isotopes of lanthanum (excluding nuclear isomers) have been characterized, ranging in mass from 117 to 155 and in half-life from 23.5 milliseconds (lanthanum-117) to 1.02 × 10 11 years (lanthanum-138). The isotope lanthanum-140 has been detected as a fission product in snow after nuclear test explosions.
