Any of several methods for determining the age of archaeological and fossil remains,rocks,etc,by measuring some property of the organic or inorganic matter that changes with time. This property may be dependent on some aspect of nuclear decay,such as the decay of the radiocarbon or the uranium series ,thermo luminescence ,or electron spin resonance. These aspects are studied by radiometric dating techniques. The property may alternatively be dependent on a chemical change with a time dependent rate constant ,such as amino acid racemization. Radiocarbon dating or carbon dating is a method for determining the age of objects up to years old containing matter that was once living,such as wood. Atmospheric carbon consists mainly of the stable isotope C and a radioactive carbon dating physics but constant proportion of C ,a radio nuclide of half life years resulting from the bombardment of atmospheric nitrogen by neutrons produced by the action of Cosmic rays.
Radiocarbon or Carbon dating is a technique used by scientist to date bones, wood, paper and cloth. Carbon is a radioisotope of Carbon. The unstable Carbon is transported down to the lower atmosphere by atmospheric activity such as storms.
Radioactive carbon dating physics
More about radioactive carbon dating physics:
Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis. Cosmic ray protons blast nuclei in the upper atmosphere, producing neutrons which in turn bombard nitrogen, the major constituent of the atmosphere. This neutron bombardment produces the radioactive isotope carbon The radioactive carbon combines with oxygen radioactive carbon dating physics form carbon dioxide and is incorporated into the cycle of living things. The carbon forms at a rate which appears to be constant, so that by measuring the radioactive emissions from once-living matter and comparing its activity with the equilibrium level of living things, a measurement of the time elapsed can be made. Presuming the rate of production of carbon to be constant, the activity of a sample can be directly compared to the equilibrium activity of living matter and the age calculated. Various tests of reliability have confirmed the value of carbon data, and many examples provide an interesting range of application. Carbon decays with a halflife of about years by the emission of an electron of energy 0.
InAntoine Becquerel discovered that a uranium-rich rock emits invisible rays that can darken a photographic plate in an enclosed container. Scientists offer three arguments for the nuclear origin of these rays. First, the effects of the radiation do not vary with chemical state; that is, whether the emitting material is in the form of an element or compound. Second, the radioactive carbon dating physics does not vary with changes in temperature or pressure—both factors that in sufficient degree can affect electrons in an atom. Third, the very large energy of the invisible rays up to hundreds of eV is not consistent with atomic electron transitions only a few eV.
Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest OK, maybe the coolest is using radioactive carbon to determine the age of old bones or plants. To understand this, you must first understand radioactivity and decay.
