Sources were held at temperatures at and below 1 kelvin for periods of several days, and exhibited an upper limit of change in the alpha-decay half-lives of the order of 1 %. Alpha Particles Q) The half life of the nuclide Rn220 is 54 5 sec What mass of radon is equivalent to 1 millicurie - Chemistry - Chemical Kinetics The three long-lived nuclides are uranium-238 (half-life=4.5 billion years), uranium-235 (half-life=700 million years) and thorium-232 (half-life=14 billion years). The fourth chain has no such long lasting bottleneck isotope, so almost all of the isotopes in that chain have long since decayed down to very near the stability at the bottom.
