New carbon dating method
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.Over the second half-life, of the atoms remaining decay, which leaves of the original quantity, and so on.In other words, the change in numbers of atoms follows a geometric scale as illustrated by the graph below.other carbon isotopes in the same ratio as exists in the atmosphere.
rock, soil, and clay produce constant low amounts of background ionizing radiation.

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.
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.
