Now, new applications for the technique are emerging in forensics, thanks to research funded by NIJ and other organizations.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.Archaeologists have long used carbon-14 dating (also known as radiocarbon dating) to estimate the age of certain objects.Traditional radiocarbon dating is applied to organic remains between 500 and 50,000 years old and exploits the fact that trace amounts of radioactive carbon are found in the natural environment.

By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.In contrast, from 1955 to 1963, atmospheric radiocarbon levels almost doubled.Since then they have been dropping back toward natural levels.Usually, atoms have an equal number of protons and neutrons.If there are too many or too few neutrons, the atom is unstable, and it sheds particles until its nucleus reaches a stable state.
