There are over forty such techniques, each using a different radioactive element or a different way of measuring them.

It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.

For this reason, many archaeologists prefer to use samples from short-lived plants for radiocarbon dating.

The development of accelerator mass spectrometry (AMS) dating, which allows a date to be obtained from a very small sample, has been very useful in this regard.

Dating is a science and discipline which requires extensive training.

misguided religious sceptics believing in the truly bizarre heresy and bida of young earthism should read an excellent article on modern geological radiometric dating Radiometric Dating A Christian Perspective Dr. Wiens quote " Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.

It is possible, particularly in dry, desert climates, for organic materials such as from dead trees to remain in their natural state for hundreds of years before people use them as firewood or building materials, after which they become part of the archaeological record.

the verification of local geochronology is crucial to the accurate dating of any one particular feature or assembly.One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains.This is a radiometric technique since it is based on radioactive decay.Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy.Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.

Coins found in excavations may have their production date written on them, or there may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.
