You've got old information, Jeannot. Modern AMS technology can detect it accurately down to around 0.025 pMC, 1/10 of the levels that we are talking about in the RATE samples. |
Dave is on to something when he talks about increased carbon dating accuracy:

New technologies, like laser-fusion and argon-argon dating methods have been refined to the point where the age of a volcanic particle as small as a grain of salt can be determined with great precision and accuracy.
Alas, poor Dave's larger argument about a young Earth is deeply undermined by these new techniques. They are still supporting and adding detail to a very old Earth. If things change, the Earth is going to start looking older, not younger. That's were the new discoveries not filtered by creationists are pointing.
