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.

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.

For instance, a date of 100,000 5,000 years ago means that there is a high probability the date is in the range of 95,000 and 105,000 years ago and most likely is around 100,000.

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.

This does not mean that radiometric dates or any other scientific measurements are unreliable.billion years, the chronometric age of a sample can be calculated.

This dating method can be used with samples that are as young as a few decades to as old as the earth and beyond.
