This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C is by far the most common isotope, while only about one in a trillion carbon atoms is C C is produced in the upper atmosphere when nitrogen N is altered through the effects of cosmic radiation bombardment a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope. The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous. It is naturally unstable and so it will spontaneously decay back into N after a period of time. It takes about 5, years for half of a sample of radiocarbon to decay back into nitrogen.

What Half Life Means for Evolution

No other element has played as large a role as carbon on our planet. Though the element has as many as 15 isotopes, only three are naturally occurring, while the rest are artificially transmuted elements, ephemeral in nature, lasting from a few nanoseconds to a few minutes. Carbon, the most abundant isotope of the element is forged in the fiery belly of a red giant star, at a temperature exceeding million Kelvin, through the fusion of Helium nuclei. Since all life on Earth is based on carbon, you could say that we are literally stardust. Would you like to write for us? Well, we're looking for good writers who want to spread the word.

Radiocarbon dating also referred to as carbon dating or carbon 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 s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
