In 1960, he was awarded the Nobel Prize in chemistry for this work.One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites.When plants fix atmospheric carbon dioxide ( allows the age of the sample to be estimated.He demonstrated the accuracy of radiocarbon dating by accurately estimating the age of wood from a series of samples for which the age was known, including an ancient Egyptian royal barge of 1850 BC.) on Earth.Carbon-14 has a relatively short half-life of 5730 years, meaning that the amount of carbon-14 in a sample is halved over the course of 5730 years due to radioactive decay.
The level of atmospheric C is not constant due to human activity, in part because of human combustion of fossil fuels and in part because of above-ground testing of the largely defensive weapon of the thermonuclear bomb.
