Carbon dating of bacteria

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. He only discussed radium, and discounted this as a major effect based on low concentrations of radium in coal (and yet my own brief stint of research has turned up many abstracts showing that concentrations of radionuclides vary widely in coal - some of these are pre-1989 so I don't know why Lowe didn't address this more carefully). on the Fundamental Aspects of Modern Physics, 2000, Luderitz, Namibia.

However, the relationship between the cell volume and its dry weight (in particular, carbon) does not depend only on the cell size and the conditions of its growth but also on the fixation and staining methods used.

Though this result is still too old to fit into any young-earth creationist chronology, it would also seem to represent a problem for the established geologic timescale, as conventional thought holds that coal deposits were largely if not entirely formed during the Carboniferous period approximately 300 million years ago.

Since the halflife of carbon-14 is 5,730 years, any that was present in the coal at the time of formation should have long since decayed to stable daughter products. "Ion Beam Preparation Systems for Atomic Isobar Reduction in Accelerator Mass Spectrometry." 2001.

(In fact that's the more common use of scintillant.

I use scintillant every day in my own work to detect H-tagged hormones.
