Practical uses of carbon dating

But soon these discarded discs could take on a different role: ...The amount of carbon-14 in the atmosphere has not changed in thousands of years.In this method, the activity of radioactive carbon ( carbon-14) present in bones, wood, or ash found in archaeological sites is measured.

The amount of carbon-14 in the wood decreases with time as it decays into nitrogen with a half-life of about 5700 years.

By comparing how much carbon-14 there is in the dead organism with the amount in a living one, the age of the dead organism can be estimated.

Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.

Carbon-14 is a radioactive isotope used to date organic material.

Its presence in organic materials is used extensively as basis of the radiocarbon dating method to date archaeological, geological, and hydrogeological samples.
