By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. After a creature's death the isotope would slowly decay away over millennia at a fixed rate. On impact in the cups, the ions set up a very weak current that can be measured to determine the rate of impacts and the relative concentrations of different atoms in the beams.

Find out what it means for an isotope to be radioactive and how. If we were to measure the ratio of 14 C to 12 C today, we would find a value of about one 14 C atom for each one-trillion 12 C atoms.
