About me:
At a very steady rate, unstable carbon gradually carbon dating description to carbon This isotope lets scientists learn the ages of once-living things. Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens — for example, wooden archaeological artifacts or ancient human remains — from the distant past. It can be used on objects as old as about 62, years. An isotope is what scientists call two or more forms of the same element. But they still have the same chemical properties. A carbon atom is a carbon atom is a carbon atom ….

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 to form carbon dioxide and is incorporated into the cycle of living things. The carbon forms at a rate which carbon dating description 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.

Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine. Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive.
