For example, a study of the Amitsoq gneisses from western Greenland used five different radiometric dating methods to examine twelve samples and got agreement to within 30 million years on an age of 3,640my.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 change into a different nuclide by radioactive decay.The decay may happen by emission of particles (usually electrons (beta decay), positrons or alpha particles) or by spontaneous nuclear fission, and electron capture.When the organism dies, it stops exchanging carbon with the atmosphere, and the ratio of carbon-14 to carbon-12 begins to decrease with the half-life of 5,730 years.Measurement of this ratio determines the age of the specimen.
