The method was developed fashionable the late s by Willard Libby , who received the Nobel Prize in Chemistry proper for his work in It is based on the truth that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.

The resulting 14 C combines with atmospheric oxygen to cut radioactive carbon dioxide , which is incorporated into plants near photosynthesis ; animals then obtain 14 C by eating the plants.

When the animal before plant dies, it stops exchanging carbon with its environment, then from that point onwards the amount of 14 C it contains begins to decrease at the same time as the 14 C undergoes radioactive decay. The older a specimen is, the less 14 C there is to be detected, and because the half-life of 14 C the period of time after which half of a given sample will enjoy decayed is about 5, years, the oldest dates that tin be reliably measured by that process date to around 50, years ago, although special homework methods occasionally permit accurate breakdown of older samples.

Research has been ongoing since the s to determine what the distribution of 14 C in the atmosphere has been over the past fifty thousand years. The resulting data, in the accumulate of a calibration curve, is now used to convert a given measurement of radiocarbon all the rage a sample into an estimation of the sample's calendar grow older. Other corrections must be made to account for the part of 14 C in unique types of organisms fractionation Prohibition, and the varying levels of 14 C throughout the biosphere reservoir effects.
