The ratio of carbon to carbon at the moment of death is the same as every other living thing, but the carbon decays and is not replaced. 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 radiocarbona radioactive isotope of carbon. Radiocarbon or Carbon dating is a technique used by scientist to date bones, wood, paper and cloth. M artin Kamen had worked for three days and three nights without sleep.
When we speak of the element Carbon, we most often refer to the most naturally abundant stable isotope 12 C.

Comparisons between the observed abundance of certain naturally occurring radioactive isotopes and their decay products, using known decay rates, can be used to measure timescales ranging from before the birth of the Earth to the present. The most common of the radioactive dating techniques currently in use involves the isotope 14 of carbon, the radiocarbon. After this reading this section you will be able to do the following :.
