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).
Can I get something radiocarbon dated?
Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of 5730 years. In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly. To obtain a truly absolute chronology, corrections must be made, provided by measurements on samples of know age.
How long does it take to radiocarbon date something?
C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to approximately 50,000 years ago, although special preparation methods occasionally make accurate analysis of older samples possible.
