Carbon dating antiques

The unreliability of carbon 14 date testing is a great concern to honest archaeologists.

Fourthly, for C14 to test accurately the artefact must have been protected from contamination.These atoms rapidly decay into radiocarbon-dioxide and along with ordinary CO2 are absorbed by living plants.As plants enter the human and animal food chains the C14 dioxide enters their living tissue.Organic matter, being porous, can easily be contaminated by organic carbon in groundwater.This increases the C12 content and interferes with the carbon ratio.
