One of the implied assumptions in radiocarbon dating is that levels of atmospheric carbon-14 have remained constant over time.This turns out not to be exactly true, and so there is an inherent error between a raw "radiocarbon date" and the true calendar date.To correct for this, scientists have compared radiocarbon dates from objects who's age is known by other means, such as artifacts from Egyptian tombs, and growth rings from ancient trees.First, the older the object, the less carbon-14 there is to measure.Radiocarbon dating is therefore limited to objects that are younger than 50,000 to 60,000 years or so.
