Creation Radiometric Dating and the Age of the Earth | Biblical Science Institute

Scientists use certain elements present in a certain abundance to calculate an approximate age for rocks. One of the decay ratios used is Uranium decaying through a series of alpha and beta decays to Lead. The number in superscript preceding the element name indicates the atomic mass, the sum of its protons and neutrons. Alpha decay releases a Helium nucleus two protons and two neutrons from the parent atom to create two atoms: the released Helium and a daughter product that has an atomic number two less than the original and an atomic mass four less than the original. Using the amount of the remaining Uranium, the amount of Lead that has built up, and the original amount of Lead which is not created by any known decay process, scientists can calculate an approximate age based on the decay rate of Uranium and the ratios of Uranium to Lead and Lead to Lead.

Creation 101: Radiometric Dating and the Age of the Earth

Uranium—lead dating , abbreviated U—Pb dating , is one of the oldest [1] and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over 4. The method is usually applied to zircon. This mineral incorporates uranium and thorium atoms into its crystal structure , but strongly rejects lead when forming. As a result, newly-formed zircon deposits will contain no lead, meaning that any lead found in the mineral is radiogenic.

The figure they could come up with was million years, only to be refuted by a more advanced study that came half a century later. The then new study put the earth to an estimated age of around 3 billion years. But sadly, this claim was also invalidated. The work must have been debilitating considering the lack of technology and sparseness of scientifically sound individuals during the time. So how did they figure out the number?
