Decay Mode and Half-life of Uranium 234

Decay mode and Half-life of Uranium 234

  • Uranium 234 decays via alpha decay to 230Th.
  • The half-life of uranium 234 is 246 000 years.
  • Uranium 234 occasionally decays by spontaneous fission with very low probability of 0.0000000017%.
  • Its specific activity is much higher ~0.0063 Ci/g.
Uranium 238 decay.
Uranium 238 decays via alpha decay (by way of thorium-234 and protactinium-234) into 234U.
