Carbon Dating - The Premise
Carbon dating is a dating technique predicated upon three things:

  • The rate at which the unstable radioactive C-14 isotope decays into the stable non-radioactive N-14 isotope,
  • The ratio of C-12 to C-14 found in a given specimen,
  • And the ratio C-12 to C-14 found in the atmosphere at the time of the specimen's death.

­You probably have seen or read news stories about fascinating ancient artifacts. At an ar­chaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old. A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 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? In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating .

Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old. It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.
