Carbon dating age of fossil

If a fossil contains 60% of its original carbon, how old is the fossil? That means this is how long it takes for half the nuclei to decay.After 5600 years, if we start with a gram, we end up with half a gram. Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.And if the artifact is organic—like wood or bone—researchers can turn to a method called radiocarbon dating.Carbon-dating Carbon dating, like other radiometric dating methods, requires certain assumptions that cannot be scientifically proved.These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.This restriction extends to animals that consume seafood in their diet.

Beyond that timespan, the amount of the original C formed by irradiation of nitrogen by neutrons from the spontaneous fission of uranium, present in trace quantities almost everywhere.Therefore dates must be calibrated based on Radiometric dating in general, of course, poses a huge problem for people who believe that the universe is 6000-odd years old.A favorite tactic of Young-Earthers involves citing studies which show trace amounts of Indeed, this results from a unique decay mode known as "cluster decay" where a given isotope emits a particle heavier than an alpha particle (radium-226 is an example.) This fact is extremely inconvenient and creationist literature, accordingly, usually does not mention it.The fluctuation of the amount of C-14 in the atmosphere over time adds a small uncertainty, but contamination by "modern carbon" such as decayed organic matter from soils poses a greater possibility for error. Thomas Seiler, a physicist from Germany, gave the presentation in Singapore.He said that his team and the laboratories they employed took special care to avoid contamination.
