The most frequently cited formula published by Cox and Dalrymple deals with the isotope ratios, instead of isotope peaks heights, considered as independent variables.

The atoms of crystalline solids, such as pottery and rock, can be altered by this radiation.

Specifically, the electrons of quartz, feldspar, diamond, or calcite crystals can become displaced from their normal positions in atoms and trapped in imperfections in the crystal lattice of the clay molecules.

Following death, however, no new carbon is consumed.

Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.

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.

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.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.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.However, paleoanthropologists rarely use it to date sites more than several million years old.
