AMS dating is important because using it you can date very small sizes carbon samples. Both Carbon and Carbon are stable, but Carbon decays by very weak beta decay to nitrogen with a half-life of approximately 5, years. In we could only calibrate radiocarbon dates until 26, years. Dating history When living things die, tissue is no longer being replaced and the radioactive decay of 14C becomes apparent. Instead of spending large amounts of time solving the problem of "when" something happened, archaeologists could now concentrate on investigating "how" and "why" things happened.
Thus Carbon is found in very low levels in the fossil fuels produced from plants and the animals that eat them. The rings could still tell how many years the tree lived, but not necessarily when. In this method, the carbon sample is first converted to carbon dioxide gas before measurement in gas proportional counters takes place. How Does Carbon Dating Work Carbon is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. In little more than a day, the entire population of Pompeii was wiped out by a volcanic eruption of Vesuvius in 79 A.
