How accurate are carbon 14 and other radioactive dating methods

The amount of thorium 230 found in the dead coral allows to measure how long it have been dead.

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.

Other methods scientists use include counting rock layers and tree rings.

CEA Radioactive hourglasses are used to date the relics of bygone civilizations, by measuring the amount of Carbon-14, whose decay rate allows for precise age calculations.The older the sample, the more carbon 14 will have decayed and the emptier the hourglass will be.Some corrections are necessary, since the amount of carbon 14 present in the atmosphere has varied over the last 40,000 years.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 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.

Carbon-14 is a radioactive carbon isotope present in the atmosphere, plants and living bodies.
