This discovery meant that there are three naturally occurring isotopes of carbon: Whereas carbon-12 and carbon-13 are stable isotopes, carbon-14 is unstable or radioactive.

Carbon-14 is produced in the upper atmosphere when cosmic rays bombard nitrogen atoms.

Modern AMS (accelerator mass spectroscopy) methods require tiny amounts, about 50 mg.

This is the clock that permits levels of c14 in organic archaeological, geological, and paleontological samples to be converted into an estimate of time.

The measurement of the rate of radioactive decay is known as its half-life, the time it takes for half of a sample to decay.

Pre-treatment seeks to remove from the sample any contaminating carbon that could yield an inaccurate date.

Acids may be used to eliminate contaminating carbonates.
