The Story of Carbon Dating Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon -14 there is left in an object . A man called Willard F Libby pioneered . . .
The process of carbon 14 dating was discovered by American chemist Willard Libby, a professor at the University of Chicago . Carbon 14 dating , consequently, changed the world of archaeology . Dating objects became relatively easy, although doing it precisely still takes some care . The rings of a tree can be used to calculate the age of a dead tree .
earth's carbon system . Radiocar-bon dating would be most suc-cessful if two important factors were true: that the concentration of carbon -14 in the atmosphere had been constant for thousands of years, and that carbon -14 moved readily through the atmosphere, biosphere, oceans and other res-ervoirs in a process known as the carbon cycle . In the absence of any historical data concerning the intensity of
Radiocarbon dating (also referred to as carbon dating or carbon -14 dating ) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon . The method was developed in the late 1940s at the University of Chicago by Willard Libby .
Carbon dating is one of the archaeology's mainstream methods for dating organic objects up to 50,000 years old . This method is based on the idea of radiative decay of Carbon -14 isotopes over thousands of years . Through physics, scientists have discovered that radioactive molecules decay at a specific rate dependent on the atomic number and . . .
History and Discovery . The discovery of carbon dates to prehistoric times and was used by ancient human civilizations as in the form of charcoal and coal . Diamonds were discovered in China in around 2500BCE . The name carbon has been derived from the word carbo (Latin for coal and charcoal) .

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 .
