Caption: MODEL RELEASED. Mass spectrometer. Researcher working on an accelerator mass spectrometer (AMS) used for carbon dating. All living material incorporates a radioactive isotope of carbon, carbon-14 (14C), and a stable isotope, carbon-12 (12C), into its tissue at a known ratio. When the tissue dies the amount of 12C remains constant, but 14C decays. Measuring the amount of 14C compared to 12C in a sample indicates how long ago the tissue died. The AMS converts atoms from a sample into a beam of ions. It then measures the mass of the ions by the application of electric and magnetic fields. Photographed at Oxford Radiocarbon Accelerator Unit, University of Oxford, UK.
