As a result of cosmic radiation a small amount of atmospheric nitrogen is transformed into radioactive nuclei which find their way into trees and plants.
As a result of cosmic radiation a small amount of atmospheric nitrogen is transformed into radioactive nuclei which find their way into trees and plants. By comparing the ratio of radioactive and stable nuclei, the age can be determined for samples up to 40,000 years old. It was developed by a team led by Willard Libby.
