Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology.
The marine reservoir effect is a phenomenon affecting radiocarbon dating. Because much of the carbon consumed by organisms in the ocean is older than that consumed by organisms on land, samples from marine life and from organisms that consumed a lot of sea-based foods while alive may appear older than they truly are when tested.
Pretreatment — It is important to understand the pretreatment applied to samples since they directly affect the final result. You are welcome to contact us to discuss the pretreatment or request that we contact you after the pretreatment and prior to dating.
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 by Willard Libby , who received the Nobel Prize in Chemistry for his work in
The physics of decay and origin of carbon 14 for the radiocarbon dating 1: We can indirectly date glacial sediments by looking at the organic materials above and below glacial sediments.
The basis of radiocarbon dating includes the assumption that there is a constant level of carbon 14 in the atmosphere and therefore in all living organisms through equilibrium. Carbon 14 is a naturally occurring isotope of the element carbon and is called radiocarbon.
