Yes, thorium does undergo beta decay. Specifically, Thorium-234 decays through beta emission to become Protactinium-234. This is part of the decay chain of Uranium-238, leading eventually to stable Lead-206.

FAQs & Answers

  1. What is beta decay? Beta decay is a type of radioactive decay in which an unstable atomic nucleus transforms into a more stable one by emitting a beta particle, which can be an electron or a positron.
  2. What is the decay chain of Thorium-234? Thorium-234 decays through beta emission to Protactinium-234, and this decay chain is a part of the larger decay process of Uranium-238, ultimately leading to stable Lead-206.
  3. What types of decay can Thorium undergo? Thorium can undergo several types of decay, including beta decay, where it transforms into different isotopes, and alpha decay, which is a common decay mode for heavier thorium isotopes.
  4. Is thorium used in nuclear energy? Yes, thorium has potential applications in nuclear energy, particularly in thorium-based reactors that can utilize thorium's ability to breed fissile uranium-233.
