Carbon dating method

In this interactive, learn how radiocarbon dating works, what it takes to determine a date in the lab, and why it's challenging to pinpoint a date precisely. Rather, it's a way to determine the age of organic remains such as bone, teeth, and seeds by finding out how much carbon-14 is left in the remains. At the very least you'll find out what it's like to date a 9,000-year-old skeleton such as Kennewick Man's.

And if the artifact is organic—like wood or bone—researchers can turn to a method called radiocarbon dating.The minerals that are used for thermoluminescence dating are mainly quartz and feldspar.The last time a crystal was reheated and its electrons were released is known as a "clock resetting event".Natural radioactivity causes latent thermoluminescence to build up so the older an object is, the more light is produced.Therefore, thermoluminescence dating is actually determining the last time a crystal was heated and electrons were released.
