Half-life by definition is the time required for a substance to reduce to half of its initial value.It is commonly used to describe how fast unstable atoms undergo radioactive decay.There are some additional methods to date inorganic materials such as potassium-argon dating and rubidium-strontium dating.These elements have a half-life of 1 billion years to 50 billion years of existence, respectively.

This process, called transmutation, is the change of one element into another as a result of changes within the nucleus.The radioactive decay and transmutation process will continue until a new element is formed that has a stable nucleus and is not radioactive.Transmutation can occur naturally or by artificial means.Through the food chain, carbon-14 reaches all living organisms.When something dies, it no longer absorbs carbon-14.
