The concentration of the radioactive isotopes can be used to monitor the cosmic-ray bombardment rate, and the accumulation of the stable species (e.g., neon-21) measures the total time since this bombardment began i.e., the time since the meteoroid was excavated by collisions from an object that was large enough to shield it from cosmic rays.
