For the shorter-lived uranium-series radionuclides, there needs to be a physical removal from uranium. In particular, how objective were the determinations by the radioisotope ages comparisons? All normal matter, such as everything on Earth, the Moon, meteorites, etc. For this reason, there is some uncertainty as one goes back towards , years. Thorium decays with a half-life of Ironically it is the slow decay rate of isotopes such as 87 Rb used for deep-time dating that makes a precise measurement of that decay rate so difficult. Ages determined by different methods would be in violent disagreement.
