It can be used for the dating organic material up to 75,000 years old. Libby (1947); his radioactive-carbon dating provided an extremely valuable tool for archaeologists, anthropologists, and earth scientists.

Libby's conclusion, with allowance for SYNONYMS OR RELATED TERMS: radiocarbon dating CATEGORY: technique DEFINITION: The occurrence of natural radioactive carbon in the atmosphere allows archaeologists the ability to date organic materials as old as 50,000 years.

dating technique relies on the progressive decay or disappearance of the radioactive parent with time.

This is now a common method for estimating the age of a carbonaceous archaeological artifacts.

The radioactivity of an artifact's content determines how long ago the specimen was separated from equilibrium with the atmosphere-plant-animal cycle.

in which the proportion of carbon isotopes is counted directly (as contrasted with the indirect Geiger counter method) using an accelerator mass spectrometer.The method drastically reduces the quantity of datable material required.. Libby showed the essential uniformity of carbon-14 in living material and went on to measure the radiocarbon level in organic samples dated historically -- materials as old as 5,000 years from sources such as Egyptian tombs.
