Definition for carbon dating

One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites.

Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.

Plants take in atmospheric carbon dioxide by photosynthesis, and are ingested by animals.

So, every living thing is constantly exchanging carbon-14 with its environment as long as it lives. The carbon in its body will remain until it decomposes or fossilizes.

Carbon dating is the result of cosmic radiation which bombards the Earth’s atmosphere, which constantly produces more 14C isotopes from 14N.

have revealed that the remains recovered - three leg bones and an arm bone from the left side of the body and fragments of skull and jaw with four teeth - belonged to a man believed to have been aged 30 to 40 whose maximum height would have been 5ft 5in.

After cessation of life, it decays with a half-life 5-57 x 103 years . The Science Dictionary is the most comprehensive source of science definitions online with over 38K science terms written and created by our global team of scientists and academic professionals.The percentage of 12 C to the remaining 14C shows the time period passed since cessation of life. A radiometric dating method for determining the age of life forms which have died in the relatively recent past, having a limit of accuracy of about 60,000 years.So, using carbon dating for fossils older than 60,000 years is unreliable.Carbon dating was developed by American scientist Willard Libby and his team at the University of Chicago.Some chemical elements have more than one type of atom. Carbon has two stable, nonradioactive isotopes: carbon-12 (12C), and carbon-13 (13C).In addition, there are trace amounts of the unstable isotope carbon-14 (14C) on Earth.The amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730 years.So, scientists can estimate the age of the fossil by looking at the level of decay in its radioactive carbon.At high geomagnetic latitudes, the carbon-14 spreads evenly throughout the atmosphere and reacts with oxygen to form carbon dioxide.Carbon dioxide also permeates the oceans, dissolving in the water.
