They can split up or ‘decay’ and release radiation.Such isotopes are called radioactive isotopes or radioisotopes.If these dates are correct, this calls the Biblical account of a recent creation of life into question.
Both are, however, 'children' of the same parent -- the Zero Point Energy.
Because of this, and because the speed of light is in the numerator of every reduced radio decay rate equation, any changes in the speed of light are indicating changes in atomic decay rates. Importantly, the original short half-life elements were also a contributor and they have gone now.

When a radioactive isotope decays, it forms a different atom with a different number of protons.
