(b) If the decay rate increased, atoms such as uranium, thorium, and samarium that decay by emitting alpha [helium nuclei] particles would have higher alpha emission energies.The alpha particles would then travel further in the mineral and damage a larger spherical halo in the mineral lattice.
The rubidium-strontium, potassium-argon, and uranium-lead decay pairs all gave ages of 72.5±0.2 million years.– Perhaps it is mainly concordant dates that get published and discordant dates are ignored.
