Carbon dating system accuracy

Because this break down occurs at a known rate it is theoretically possible to compare the amount of regular carbon and the amount of radioactive carbon and estimate just how long an organism has been dead.Although the theory of radiocarbon dating is interesting, there are several inherent problems with the process.It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said.

If one of these rays collides with an atom, it would create a secondary cosmic ray and become an energetic neutron.

In order for carbon dating to be accurate, we must know what the ratio of carbon-12 to carbon-14 was in the environment in which our specimen lived during its lifetime.

during the industrial revolution more carbon-12 was being produced offsetting the ratio a bit).

They have their work cut out for them, however, because radiocarbon (C-14) dating is one of the most reliable of all the radiometric dating methods. - What is the level of accuracy of this dating method?

Why are there discrepancies in results when using this method?
