Examples of isotopes used in radiometric dating

This assumption is backed by numerous scientific studies and is relatively sound.

However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.

Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.

Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.

his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.

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).

In early twentieth century, Thomson’s plain cake model prompted Rutherford to replace it by Saturn model where he described the atom as consisting of a small central nucleus surrounded by electrons and rotating in rings.

This view was supported by a study of the behaviour of a beam of alpha particles and directed on a thin gold metal foil.

To get to that point, there is also a historical discussion and description of non-radiometric dating methods.

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.

The example used here contrasts sharply with the way conventional scientific dating methods are characterized by some critics (for example, refer to discussion in "Common Creationist Criticisms of Mainstream Dating Methods" in the Age of the Earth FAQ and Isochron Dating FAQ).

A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.
