To be able to determine radiocarbon many years it is important to obtain the quantity of radiocarbon in an example. This dimension are made both by calculating the radioactivity associated with test (the traditional method that is beta-counting or by straight counting the radiocarbon atoms making use of a way known as Accelerator Mass Spectrometry (AMS).
Dimension of this radioactivity regarding the test is effective in the event that test is huge, however in 9 months lower than 0.01per cent of this radiocarbon ions will decay, therefore inside a fair dimension time (typically 2-3 weeks) just a tremendously little percentage for the radiocarbon atoms tend to be recognized by this process.
