Uses of radioactive dating

The method does not count beta particles but the number of carbon atoms present in the sample and the proportion of the isotopes. Samples that have been radiocarbon dated since the inception of the method include charcoal, wood, twigs, seeds, bones, shells, leather, peat, lake mud, soil, hair, pottery, pollen, wall paintings, corals, blood residues, fabrics, paper or parchment, resins, and water, among others.Physical and chemical pretreatments are done on these materials to remove possible contaminants before they are analyzed for their radiocarbon content.Liquid scintillation counting is another radiocarbon dating technique that was popular in the 1960s.In this method, the sample is in liquid form and a scintillator is added.Such artificially produced radioactive elements are called radioactive isotopes or radioisotopes.Here is some example of the production of radioisotopes: Radioisotopes have proved to be beneficial to mankind in the sphere of medicine and industry.

These are produced by natural radioactivity as by artificial transmutations,and have the some chemical properties as their inactive counter parts.The stable and non-radioactive elements can also be changed into radioactive elements .Such artificially produced radioactive elements are called radioactive isotopes.They emit different types of radiations, all the time, and hence continuously change from one type of element to another.The stable and non-radioactive elements can also be changed into radioactive elements by bombarding them with protons, neutrons or alpha particles.
