The relatively short half-life of carbon-14, 5,730 years, makes the reliable only up to about 50,000 years.

The technique often cannot pinpoint the date of an archeological site better than historic records, but is highly effective for precise dates when calibrated with other dating techniques such as tree-ring dating.

An additional problem with carbon-14 dates from archeological sites is known as the "old wood" problem.

It is possible, particularly in dry, desert climates, for organic materials such as from dead trees to remain in their natural state for hundreds of years before people use them as firewood or building materials, after which they become part of the archaeological record.

This is a radiometric technique since it is based on radioactive decay.

Cosmic radiation entering the earth’s atmosphere produces carbon-14, and plants take in carbon-14 as they fix carbon dioxide.

Thus dating that particular tree does not necessarily indicate when the fire burned or the structure was built.

For this reason, many archaeologists prefer to use samples from short-lived plants for radiocarbon dating.The new test gives publishers control over pricing, offers, subscriber relationships, and 100% of the revenue.
