Is radiometric age dating accurate

In fact, they track because radiometric data is accurate.

An expert scientist summarizes: "The first radiometric dates, generated about 1920, showed that the Earth was hundreds of millions, or billions, of years old.

The coral record verifies that radiometric methods are accurate. For the purposes of assessing accuracy, each of the methods is assumed to be applied in accordance with the established methods and technology.

By analogy, a stop watch will not keep accurate time if it is not wound, if it is not in good repair, or if the operator forgets to press the button.

Age estimates can be cross-tested by using different isotope pairs.

Results from different techniques, often measured in rival labs, continually confirm each other.

Coral growth patterns are also seasonal and provide a long independent date history. The dates obtained by different radiometric isotope pairs cross-check each other.

Methods are precise insofar as they are properly used.

A good explanation of all of the dating methods used for samples up to about 200,000 years old, together with their accuracies and references to the scientific literature is contained in [1] Walker, Mike, "Quaternary Dating Methods," John Wiley & Sons, 2005

The actual accuracy of radiometric dating is about 2%, but there is no point in splitting hairs for this debate as to whether it is 2% or 3%.

An error of 90% would, for example, still disprove Young Earth Creationism.There are about two dozen decay pairs used for dating.
