In recent years, forensic scientists have started to apply carbon-14 dating to cases in which law enforcement agencies hope to find out the age of a skeleton or other unidentified human remains.

In contrast, from 1955 to 1963, atmospheric radiocarbon levels almost doubled.Adult teeth are formed at known intervals during childhood.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.To determine year of death, the researchers used radiocarbon levels in soft tissues.

Unlike tooth enamel, soft tissues are constantly being made and remade during life.

Atmospheric dispersion tends to create uniform levels of carbon-14 around the globe, and researchers believe that these would be reflected in human tissues regardless of location.
