In this section we will explore the use of carbon dating to determine the age of fossil remains. Carbon dating is based upon the decay of 14C, a radioactive isotope of carbon with a relatively long half-life ( years). While 12C is the most abundant.

If you're seeing this message, it means we're having trouble loading external resources on our website. Radiocarbon dating is a method for determining the age of an object containing organic .. Calculating radiocarbon ages also requires the value of the half-life for C. In Libby's paper he used a value of ± 47 years, based on. 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.

Unstable nuclei decay. The technique of comparing the abundance ratio of a radioactive isotope to a The isotope 14C is radioactive, and beta-decays with a half-life of 5, years. 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.

When we speak of the element Carbon, we most often refer to the most naturally abundant stable isotope 12 C. Although 12 C is definitely essential to life, its unstable sister isotope 14 C has become of extreme importance to the science world. Radiocarbon Dating is the process of determining the age of a sample by examining the amount of 14 C remaining against the known half-life, 5, years. The reason this process works is because when organisms are alive they are constantly replenishing their 14 C supply through respiration, providing them with a constant amount of the isotope.

Theoretically, if one could detect the amount of carbon in an object, one could establish that object's age using the half-life, or rate of decay, of the isotope.
