Define radiocarbon dating
C and counting the amount of each) allows one to date the death of the once-living things.
Perhaps you have heard of Ice Man, a man living in the Alps who died and was entombed in glacial ice until recently when the ice moved and melted.
The researchers found that if they assumed tooth enamel radiocarbon content to be determined by the atmospheric level at the time the tooth was formed, then they could deduce the year of birth.
They found that for teeth formed after 1965, enamel radiocarbon content predicted year of birth within 1.5 years.
The researchers found that certain soft tissues — notably blood, nails and hair — had radiocarbon levels identical to the contemporary atmosphere.
Everyone born after that would be expected to have the same level of carbon-14 that prevailed before the nuclear testing era.To determine year of birth, the researchers focused on tooth enamel.Adult teeth are formed at known intervals during childhood.The researchers found that year-of-death determinations based on nails were accurate to within three years.The generally poor post-mortem preservation of soft tissues would be a limiting factor to this approach.
