Symposium on uses of radioactive carbon dating

Radiocarbon is then taken in by plants through photosynthesis, and these plants in turn are consumed by all the organisms on the planet.

Therefore, radiocarbon dates need to be calibrated with other dating techniques to ensure accuracy.

Plants are not the only organism that can process Carbon-14 from the air.

The Mayan calendar used 3114 BC as their reference.

More recently is the radiocarbon date of 1950 AD or before present, BP.

When it comes to dating archaeological samples, several timescale problems arise.

For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).Absolute dating represents the absolute age of the sample before the present.Historical documents and calendars can be used to find such absolute dates; however, when working in a site without such documents, it is hard for absolute dates to be determined.Limitations and calibration: When Libby was first determining radiocarbon dates, he found that before 1000 BC his dates were earlier than calendar dates.He had assumed that amounts of Carbon-14 in the atmosphere had remained constant through time.The Greeks consider the first Olympic Games as the beginning or 776 BC.
