Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.

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.AMS dating, for example, involves burning a sample to convert it to graphite.Advantages of AMS Radiocarbon Dating over Radiometric Analysis by LSC:(a) small sample size needed (as little as 20 mg) thus it is recommended for radiocarbon dating of blood particles, grains, seeds, small artifacts, or very expensive or rare materials;(b) takes less time than radiometric method (less than 24 hours);(c) higher precision than radiometric techniques.The rate of decay (given the symbol λ) is the fraction of the 'parent' atoms that decay in unit time.For geological purposes, this is taken as one year.
