Examples of radiocarbon dating

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. These techniques can allow measurement of dates up to 60, and in some cases up to 75, years before the present. Because the radiocarbon is radioactive, it will slowly decay away. There are several other possible sources of error that need to be considered. The ratio of 14 C to 12 C is approximately 1. Older dates have been obtained by using special sample preparation techniques, large samples, and very long measurement times.

To learn more, please view our Privacy Policy. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. A much larger effect comes from above-ground nuclear testing, which released large numbers of neutrons and created 14 C. Concepts Deep time Geological history of Earth Geological time units. Subsequently, a sample from the fossil forest was used in an interlaboratory test, with results provided by over 70 laboratories. For decades after Libby performed the first radiocarbon dating experiments, the only way to measure the 14 C in a sample was to detect the radioactive decay of individual carbon atoms.
