Radiocarbon dating reference year

Buckland's immediate successors did a little better.They determined that the Red Lady was in fact a man, and that the ornaments resembled those found at much older sites in continental Europe.

Such stories misrepresent the truth and do a disservice to science and public knowlege.(Aardsma, 1994, page 2.)The original reference [Trautman and Willis, page 200.] in the second case (natural gas) immediately reveals that both Whitelaw and The Answers Book have, unfortunately, neglected several very important " The sensitivity of the equipment used to make the radiocarbon measurements on these natural gas samples was limited to 30,000 to 34,000 years---the equipment was unable to measure back further. In this example, old radiocarbon dates from living clams or snails are given as evidence which discredits the reliability of radiocarbon dating. Aardsma addressed this issue in a 1989 article: The shells of freshwater clams can, and often do, give anomalous radiocarbon results.However, the reason for this is understood and the problem is restricted to only a few special cases, of which freshwater clams are the best-known example.If this water is in contact with significant quantities of limestone, it will contain many carbon atoms from dissolved limestone.Since limestone contains very little, if any, radiocarbon, clam shells will contain less radiocarbon then would have been the case if they had gotten their carbon atoms from the air.
