Releasing Particles Radioactivity occurs when an atomic nucleus breaks down into smaller particles. For carbon the half-life is a mere ± 30 years (see radiocarbon dating). It is important that the radioactive isotope be contained within the sample being.

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. The method was developed in the late s by Willard Libbywho received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxidewhich is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.
