radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon in which trace radioactive impurities were selectively incorporated when they were formed the method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products which form at a known constant rate of decay.

radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.

Scientists look at halflife decay rates of radioactive isotopes to estimate when a particular atom might decay a useful application of halflives is radioactive dating this has to do with figuring out the age of ancient things if you could watch a single atom of a radioactive isotope u238 for example you wouldnt be able.

radioactive isotopes will decay in a regular exponential way such that onehalf of a given amount of parent material will decay to form daughter material in a time period called a halflifea halflife is not onehalf the age of the rock when the material is liquid or gaseous the parent and daughter isotopes can escape but when the material solidifies they cannot so the ratio of parent to.

To demonstrate that the rates of decay of unstable nuclei can be measured that the exact time that a certain nucleus will decay cannot be predicted and that it takes a very large number of nuclei to find the rate of decay this is the second lesson in a threelesson series about isotopes.

Carbon dating is used to determine the age of biological artifacts up to 50000 years old this technique is widely used on recent artifacts but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.
