Radioactive dating of organic materials mendatingmanual com
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.While not all objects have the same isotopes, both living and nonliving objects have some sort of decaying, radioactive isotope that can be used based on known decay rates. An isotope of some sort is located and isolated within an object.
The sample is ionized using the ionic generator and then passed through a magnetic field that separates the samples into different groups based on their mass and ionization levels.The method works best if neither the parent nuclide nor the daughter product enters or leaves the material after its formation.Anything which changes the relative amounts of the two isotopes (original and daughter) must be noted, and avoided if possible.However, samples must be taken from several different areas of the object being studied to ensure maximum accuracy.Also, radiometric dating relies on the principle that the isotope has remained in the object since its creation.

However, Carbon-14 tests are conducted on relatively young, organic objects because organisms only replenish Carbon-14 while they are alive.
