The isotopes can also be used in plants to measure the amount of radioactivity in the leaves.Isotopes are variations of chemical elements containing different numbers of neutrons.One popular radioactive dating method is called carbon dating -- the dating of organic materials.Because the life of a radioisotope isn't affected by any influence outside of the nucleus, its predictable rate of decay acts like a clock.By studying carbon and oxygen isotope data, it's possible to determine where in the Mediterranean various olive oils come from, and how "natural" fruit juice products are.Unusual isotopes can be used as markers in chemical reactions.Isotopes are used as sources of radiation in medicine, sterilization, nondestructive control, etc.- Isotopes can be used as tracers - Isotopes can be used as energy source - Isotopes are used for radioactive dating - Isotopes are used…

Carbon-13 has 6 protons, just like other carbon isotopes, but it has 7 neutrons.The amino acids are incorporated into the proteins being studied and, because they behave identically to one another despite their differing nuclear composition, newly synthesized proteins can be more closely studied alongside their controlled (naturally occurring) counterparts.Radioactive isotopes are often used to measure the age of materials containing carbon.Because of the different number of neutrons, carbon-12 and carbon-14 differ with respect to radioactivity.Carbon-14, on the other hand, undergoes radioactive decay:e (half-life is 5720 years)The other common isotope of carbon is carbon-13.
