How does radiocarbon dating work all plants and animals on earth are made principally of carbon during the period of a plant's life, the plant is taking in carbon dioxide through photosynthesis, which is how the plant makes energy and grows. 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 (14 c), a radioactive isotope of carbon.
Conventional carbon dating estimates the age of an artifact based on its content of carbon-14 (c-14), a naturally occurring, radioactive form of carbon comparing the c-14 levels in the object to levels of c-14 expected in the atmosphere for a particular historic period allows scientists to estimate the age of an artifact.

The most suitable types of sample for radiocarbon dating are charcoal and well-preserved wood, although leather, cloth, paper, peat, shell and bone can also be used because of the somewhat short half-life of 14c, radiocarbon dating is not applicable to samples with ages greater than about 50,000 years, because the remaining concentration would be. Carbon dating chinese antiques this is used for organic materials such as chinese works of art constructed from: wood ivory bone textiles (for example, canvas) carbon dating measures the amount of carbon 14 to determine the time of death of the organism in the case of a tree, then this would be when it was cut down and cotton.
