Prices start at just $126 for radiocarbon analysis of previously prepared graphite, and increase to $460 for a standard analysis including a common extraction protocol (used for sub-fossil charcoal, peat, seeds and others).

How accurate is wood carbon dating?

Any charcoal or wood sample that is carbon dated will have an apparent age, which may result in errors of up to hundreds of years unless short-lived tree species or twigs are selected for radiocarbon dating.
