Web23 Jul 2024 · Nuclear Transmutation Decay Reactions, Alpha Decay, Beta Decay, and Gama Decay. July 23, 2024. written by Adeel Abbas. Nuclear transmutation is the conversion of one radioactive element into another radioactive element. In nuclear transmutation, different types of radiation are produced. 234Th is an isotope of thorium whose nuclei contain 144 neutrons. 234 Th has a half-life of 24.1 days, and when it decays, it emits a beta particle, and in doing so, it transmutes into protactinium -234. 234 Th has a mass of 234.0436 atomic mass units (amu), and it has a decay energy of about 270 keV ( … See more Thorium (90Th) has seven naturally occurring isotopes but none are stable.
