One of the tools available to scientists who study ancient history (natural and human) is carbon-14 dating (also known as carbon dating or radiocarbon dating). This method is used, within limits, to determine the ages of objects (bone, charcoal, plant material, etc.) that contain carbon.
As long as an organism consumes carbon-containing materials, it will maintain a constant 14C/12C ratio. Organisms die and II decay through natural processes. Any decrease in the total amount of carbon due to decompo-sition will not affect the 14C/12C ratio.
Carbon with 6 protons and 8 neutrons is called carbon-14 (14C). This is an unstable radioactive isotope. About 1 in 1012 carbon atoms in the atmosphere is 14C. In the process the 14N becomes 14C, and a H+ ion (a proton) is released.

Carbon dating 1 Carbon-14 is a radioactive isotope that occurs naturally. Scientists use carbon-14 to help find the age of old pieces of wood. This technique is called carbon dating. It uses the idea of half-life. (a) Which of these describes half-life? Put a cross ( ) in the box next to your answer. (1)
To discover the year of death, subtract the current year from the age. Round each answer to the Using the "report your findings" worksheet, notify the museum of your results.
Carbon Dating Practice Problems focus mainly on determining the age of ancient objects using the half-life and activity of the 14C nuclei.
