This guy looks like Canelo Alvarez. 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 14 C , a radioactive isotope of carbon. The method was developed by Willard Libby in the late s and soon became a standard tool for archaeologists. Suspension bondage Libby received the Nobel Prize in Chemistry for his work in The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.Carbon makes up about 1 part per trillion of the carbon atoms around us, and this proportion remains roughly constant due to continual production of carbon- 14 from cosmic rays. The half life of carbon is about 5, years, so if we measure the proportion of C in a sample and discover it's half a part per trillion , i.e. Amongst accelerator laboratories there has been mooted the theoretical possibility of extended range dating to 75 yr +, at present this seems difficult to attain because of the problems in accurately differentiating between ions that mimic the mass and charge characteristics of the C14 atom. Beukens () for instance.

Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.
