WebAfter the dating elements have been isolated, they are loaded into a mass spectrometer and their relative isotopic abundances determined. The abundance of certain isotopes used for dating is determined by counting the number of disintegrations per minute (i.e., emission activity). The rate is related to the number of such atoms present through ...
