These energy charged electrons progressively accumulate over time.

Such contamination can occur if a sample is exposed to carbon compounds in exhaust gasses produced by.

In addition, any argon that existed prior to the last time the rock was molten will have been driven off by the intense heat.

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

rock, soil, and clay produce constant low amounts of background ionizing radiation.

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.
