Although one can simply measure older samples for longer times, there are practical limits to the minimum sample activity that can be measured.At the present time, for a 1 milligram sample of graphite, this limiting age is about ten half-lives, or 60,000 years, if set only by the sample size.A unique characteristic of 14C is that it is constantly formed in the atmosphere.Production and decay 14C atoms are produced in the upper atmosphere where neutrons from cosmic rays knock a proton from nitrogen-14 atoms.These newly formed 14C atoms rapidly oxidize to form 14CO..Photosynthesis incorporates 14C into plants and therefore animals that eat the plants.Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.It makes no sense at all if man appeared at the end of billions of years.

Because this decay is constant it can be used as a “clock” to measure elapsed time assuming the starting amount is known.

In AMS, the filiamentous carbon or "graphite" derived from a sample is compressed into a small cavity in an aluminum "target" which acts as a cathode in the ion source.

The surface of the graphite is sputtered with heated, ionized cesium and the ions produced are extracted and accelerated in the AMS system.

Some of these atomic arrangements are stable, and some are not.

The unstable isotopes change over time into more stable isotopes, in a process called radioactive decay.
