MODEL RELASED: Radiocarbon dating. Control console of a linear accelerator (linac) used in radiocarbon dating. This analyses the amount of carbon-14 (14C) in carbon dioxide,produced by the combustion of a sample in oxygen. The linac is used as the mass of 14C is so close to that of nitrogen-14 from the sample. The ratio of radioactive 14C to stable carbon-12 may be related to the time since the death of the animal or plant being investigated. Convention states that 14C has a half-life of 5568 years (+/- 30 years),but this is now thought to be too short. Dates are given either as radiocarbon dates,or solar dates after corrections have been made | |
