Although, organic materials as old as 100,000 years potentially can be dated with AMS, dates older than 60,000 years are still rare.

When a sample is heated to high temperatures in a laboratory, the trapped electrons are released and return to their normal positions in their atoms.Radiometric dates, like all measurements in science, are close statistical approximations rather than absolutes.This will always be true due to the finite limits of measuring equipment.It is also based on the fact that background radiation causes electrons to dislodge from their normal positions in atoms and become trapped in the crystalline lattice of the material.When odd numbers of electrons are separated, there is a measurable change in the magnetic field (or spin) of the atoms.Since the magnetic field progressively changes with time in a predictable way Whenever possible, paleoanthropologists collect as many dating samples from an ancient human occupation site as possible and employ a variety of chronometric dating methods.
