Carbon dating works by basing an age calculation on the ratio of radioactive carbon (C) in the atmosphere before nuclear bomb testing to the same ratio in the sample. Using a formula that compares that ratio to a standard modern ratio produces a “percent modern carbon” (p MC) value that scientists use to estimate carbon ages for carbon-containing materials.

Carbon-14 (C at levels detectable by modern instruments.[i] Carbon dating of historical objects of known age is sometimes accurate back to about 1,000 BC, as verified by historical records.[ii] Carbon-14 dating begins with sound, repeatable science when researchers record isotope ratios.

For example, in AD 774–775 there was an increase of 1.2% in the C content of tree rings, which was about 20 times as high as the background rate of variation.[ix] This “spike” was followed by a decline that lasted several years.Several unknown factors can seriously impact carbon ratios.Just a partial list of these factors includes: Factor 1: Forest fires.By measuring the ratio of carbon-12 to carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of the artifact.Carbon dating assigns ages to once-living materials such as wood, bone, teeth, and shells.

In order to date the artifact, the amount of Carbon-14 is compared to the amount of Carbon-12 (the stable form of carbon) to determine how much radiocarbon has decayed.
