It is not about the theory behind radiometric dating methods, it is about their , and it therefore assumes the reader has some familiarity with the technique already (refer to "Other Sources" for more information).As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.These are often characterised as the norm, rather than the exception.The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.This restriction extends to animals that consume seafood in their diet.To get to that point, there is also a historical discussion and description of non-radiometric dating methods.

This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.These are released as radioactive particles (there are many types).Learn about different types of radiometric dating, such as carbon dating.Understand how decay and half life work to enable radiometric dating.The rate of decay (given the symbol λ) is the fraction of the 'parent' atoms that decay in unit time.
