Different radiometric dating techniques

Let us critically examine each of these claims and see if they hold up against the science.While doing so, we will have to learn about how radiometric dating works.A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will spontaneously transform into a different nuclide.This transformation may be accomplished in a number of different ways, including radioactive decay, either by emission of particles (usually electrons (beta decay), positrons or alpha particles) or by spontaneous fission, and electron capture.Radiometric dating is a technique used to date materials based on a knowledge of the decay rates of naturally occurring isotopes, and the current abundances.It is our principal source of information about the age of the Earth and a significant source of information about rates of evolutionary change.

Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.

There are many different kinds of radiometric dating and not all conclusions we will reach can be extrapolated to all methods used.

Also, different radiometric dating techniques independently converges with each other and with other dating techniques such as dendrochronology, layers in sediment, growth rings on corals, rhythmic layering of ice in glaciers, magnetostratigraphy, fission tracks and many other methods. There exists different versions, or isotopes of many elements.

So the claimed ages of many millions of years, which are based on today’s slow decay rates, are totally unreliable.

Does this mean we should throw out the radioactive clocks? The general principles of using radioisotopes to date rocks are sound; it’s just that the assumptions have been wrong and led to exaggerated dates.
