So that you can determine radiocarbon ages it is important to get the level of radiocarbon in an example. This dimension may be made either by calculating the radioactivity for the test (the standard beta-counting technique) or by straight counting the radiocarbon atoms making use of a way called Accelerator Mass Spectrometry (AMS).

Dimension regarding the radioactivity of this test is effective in the event that test is big, however in 9 months lower than 0.01per cent associated with radiocarbon ions will decay, therefore in a measurement that is reasonable (typically a couple weeks) just a tremendously little percentage associated with the radiocarbon atoms are detected by this technique.
