Linear accelerator used in radiocarbon dating
Numéro d’image : 11826017
| MODEL RELEASED: Radiocarbon dating. Samples of carbon dioxide being loaded into a linear accelerator (linac) for radiocarbon dating. This analyses the amount of carbon-14 (14C) in the gas,produced by the combustion of the 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 are made | |
