Radiocarbon dating is the principal method for determining the age of carbon-bearing materials from the present to about 50,000 years ago.The method takes advantage of the natural occurrence of a radioactive isotope of carbon (C in samples of ancient carbon compounds and comparing this with the amount in modern materials, it is possible to determine the time of cessation of carbon exchange with the atmosphere.

The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.

Free 5-day trial Ever wondered how scientists know the age of old bones in an ancient site or how old a scrap of linen is?

The technique used is called carbon dating and in this lesson we will learn what this is and how it is used. Carbon dating, or radiocarbon dating, is a method used to date materials that once exchanged carbon dioxide with the atmosphere. In the late 1940s, an American physical chemist named Willard Libby first developed a method to measure radioactivity of carbon-14, a radioactive isotope.

Dating a dictator can be a scary and dangerous endeavor.

But it also offers an opportunity to meet the authoritarian oppressor of your dreams, provided that the proper precautions are taken.
