For example if there are only 25% of the carbon-14 atoms to carbon-12 atoms that there are in the atmosphere then the sample must be 2 half-lives old.This technique is better because you use all the carbon-14 atoms, not just the ones that happen to be decaying at the time.This relationship has occurred most noticeably in the break up and formation of continents and the resulting effect on climate. Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more than 50,000 years old.Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.

Plate tectonics and the carbon cycle are intertwined in several different ways.This restriction extends to animals that consume seafood in their diet.As stated previously, carbon dating cannot be used on artifacts over about 50,000 years old.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.

Because of this you can use a much smaller sample: as little as a few milligrams.
