Carbon dating formula half life

This decay is an example of an exponential decay, shown in the figure below.

Knowing about half-lives is important because it enables you to determine when a sample of radioactive material is safe to handle.

A useful application of half-lives is radioactive dating.The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.In this equation, the units of measure for N and No can be in grams, atoms, or moles.It does not matter as long as they are like measures.

The method of carbon dating makes use of the fact that all living organisms contain two isotopes of carbon, carbon-12, denoted 12C (a stable isotope), and carbon-14, denoted 14C (a radioactive isotope).
