Start Carbon dating fossil fuels

Carbon dating fossil fuels

The aim is to find fossil fuels that have a or less; below that, neutrino activity can be reliably detected.

Presumably most of these bacteria never interact with the "modern" C.

(4) Lowe goes on to make recommendations about using only freshly mined dry coal stored under inert gas, and other recommendations about choice of "background" for radiocarbon labs.

The Problem: Accelerator mass spectrometry (AMS), a sensitive radiometric dating technique, is in some cases finding trace amounts of radioactive carbon-14 in coal deposits, amounts that seem to indicate an age of around 40,000 years.

(This research is part of the "Old Carbon Project" funded by the U. National Science Foundation's Particle and Nuclear Astrophysics Program and also by Canada's Natural Science and Engineering Research Council.

The team will be presenting results to date this September at the 9th International Conference on Accelerator Mass Spectrometry in Japan.) Finally, I did also get a copy of David Lowe's 1989 Radiocarbon paper. A summary: (1) old coal often has a little more C by radioactive decay.

I picked him to bother with my emails because he had recently written some nice review articles about the AMS technique in the Radiocarbon journal.
