Charcoal and wood are two of the most widely used materials for accelerator mass spectrometry AMS radiocarbon dating. AMS labs prefer to carbon date charcoal and wood because these materials do not need complex pretreatment. Willard Libby, the pioneer of radiocarbon dating , identified charcoal to be the most reliable material to carbon date. The time-width of an organism refers to its total growth and exchange period with the biosphere. The time-width affects the way radiocarbon age is converted into calendar age for a sample. If this is not the case, such as in wood, the radiocarbon age of the organism at death is not zero.

Carbon Dating Gets a Reset

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon. At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.

Radiocarbon dating also referred to as carbon dating or carbon 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 s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
