Learn about different types of radiometric dating, such as carbon dating.Understand how decay and half life work to enable radiometric dating.For example, the element Uranium exists as one of several isotopes, some of which are unstable.When an unstable Uranium (U) isotope decays, it turns into an isotope of the element Lead (Pb).This is then transformed into isotopic ratios and then used to date the material.The machinery you use has to be tuned and calibrated to which isotopes you want to measure and needs to be set with the correct running conditions.
It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for "young Earth" theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques.
These are often characterised as the norm, rather than the exception.
I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.
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.
To get to that point, there is also a historical discussion and description of non-radiometric dating methods.
