Carbon-14 is a naturally occurring isotope of the element carbon.
So the amount of carbon 14 is very small - but it is detectable. After 57,300 (ten half lives) only 1/1024 (1/2^10) of the original carbon 14 is left - which limits its usefulness to objects less than 60,000 years old. The method makes the following assumptions: 1) The ratio of carbon 14 to stable carbon is constant.Other suggestions that decay rates are affected by neutrino fluxes or other factors have generally been discounted. 6) The sample represents carbon 14 in the atmosphere at the time. A wooden artifact for example may have been cut from wood taken from the core of a 100 year old tree.In this case the carbon 14 age would be 100 years older than the date of manufacture.Many isotopes have been studied, probing a wide range of time scales.C and counting the amount of each) allows one to date the death of the once-living things.
