Shortly after Becquerel's find, Marie Curie, a French chemist, isolated another highly radioactive element, .The realisation that radioactive materials emit rays indicated a constant change of those materials from one element to another.

Kelvin defended this calculation throughout his life, even disputing Darwin's explanations of evolution as impossible in that time period.I found several good sources, but none that seemed both complete enough to stand alone and simple enough for a What is radiometric dating?Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock.' It relies on three basic rules, plus a couple of critical assumptions.Radiometric dating methods are the strongest direct evidence that geologists have for the age of the Earth.All these methods point to Earth being very, very old -- several billions of years old.

(For a brief science review, see sidebar and figure 1.) The timepiece that allows dating is the “radioactive” decay of certain kinds of atoms from one form into another.
