The development of low-energy plasma oxidation as a sampling technique has created new opportunities for applying radiocarbon dating. Plasma oxidation can be carried out at energies below the threshold of carbonate and oxalate dissociation, dramatically reducing the need for pretreatment and subsequent loss of sample volume. Radiocarbon sample size can be reduced toward the minimum of the 40-100 millionths of a gram of carbon that is actually needed for standard AMS dating. This allows the...
