Web20 mei 2014 · At its most basic level, carbon dating is the method of determining the age of organic material by measuring the levels of carbon found in it. Specifically, there are two types of carbon found in organic materials: carbon 12 (C-12) and carbon 14 (C-14). It is imperative to remember that the material must have been alive at one point to absorb ... Radiocarbon dating (also referred to as carbon dating or carbon-14 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.
