Archaeologists have long used carbon dating also known as radiocarbon dating to estimate the age of certain objects. Traditional radiocarbon dating is applied to organic remains between and 50, years old and exploits the fact that trace amounts of radioactive carbon are found in the natural environment. 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 dating to cases in which law enforcement agencies hope to find out the age of a skeleton or other unidentified human remains.

Radiocarbon dating, or carbon dating, is a scientific method that can accurately determine the age of organic materials as old as approximately 60, years. First developed in the late s at the University of Chicago by Willard Libby, the technique is based on the decay of the carbon isotope. The invention of radiocarbon dating elegantly merged chemistry and physics to develop a scientific method that can accurately determine the age of organic materials as old as approximately 60, years.

You probably have seen or read news stories about fascinating ancient artifacts. An archaeologist finds a child mummy high in the Andes and says the child lived more than 2, years ago. How do scientists know how old an object or human remains are? What methods do they use and how do these methods work?
