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.
There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
It may be used to date a wide range of natural and man-made materials.
Whilst there is some truth in this for the standard radiometric dating techniques, the process of isochron dating completely removes these objections. I can't emphasise enough how important it is to understand this process in order to gain complete confidence in radiometric dating.
Radiometric dating (often called radioactive dating) is a way to find out how old something is.
The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. It is the main way to learn the age of rocks and other geological features, including the age of the Earth itself.
All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.
Elements exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.
