The dating of rocks by the radioactive decay of certain minerals is undoubtedly the main argument today for the dogma of an old earth but the bible clearly teaches a recent creation of both the heavens and the earth, so christians have often tried to reinterpret this doctrine to accommodate the long ages required by radioactive dating.

When a nucleus undergoes radioactive decay – or decays, radioactively – it changes its state to one of a lower energy, and emits a particle (sometimes more than one), a gamma ray, or both (and one type of radioactive decay involves the absorption, or capture, of an electron as well emission of a.
