A new series of radiocarbon measurements from Japan's Lake Suigetsu will give scientists a more accurate benchmark for dating materials, especially for older objects, according to a research team that included Oxford University's Radiocarbon Accelerator Unit. The research team extracted cores of beautifully preserved layers of sediment, containing organic material such as tree leaf and twig fossils , from the bottom of the Japanese lake where they had lain undisturbed for tens of thousands of years. As an article in the journal Science explains, the findings are hugely significant because they provide a much more precise way to examine radiocarbon ages of organic material for the entire 11,,year time range. For example, archaeologists should now be able to pinpoint more accurately the timing of the extinction of Neanderthals or the spread of modern humans into Europe.

In the Catholic Church gave permission for a piece of the Shroud of Turin to be cut out and tested to determine its age by means of radio carbon dating. Dank moderner Messverfah re n Radiokarbonmethode i st es heute möglich, Rückschlüsse auf die Sonnenaktivität in früheren Jahrhunderten und Jahrtausenden zu ziehen. Thanks to modern measuring techniques radiocarbon dating it i s nowadays possible to come to accurate conclusions about the activities of the sun in previous centuries and thousands of years ago.
