As a result, there is a changing ratio of carbon-14 to the more atomically stable carbon-12 involves actually counting individual carbon-14 atoms.

This allows the dating of much older and smaller samples but at a far higher cost.

decay or the rate of other cumulative changes in atoms resulting from radioactivity. The various isotopes of the same element differ in terms of atomic mass but have the same atomic number..

One half-life is the amount of time required for of the original atoms in a sample to decay.

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

For instance, if a site is believed to be over 100,000 years old, dendrochronology and radiocarbon dating could not be used.These energy charged electrons progressively accumulate over time.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.
