The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past.

This is because the amount and strength of cosmic radiation entering the earth's atmosphere has varied over time.

There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.

The unstable nature of carbon 14 (with a precise half-life that makes it easy to measure) means it is ideal as an absolute dating method.

Radiocarbon doesn’t work well on objects much older than twenty thousand years for such objects have small amounts of C-14 left in them.

Carbon dating methods have three basic assumptions that may not necessarily be true: 1-The assumption that the starting point of dating is Zero.

The following article is primarily based on a discussion of radiocarbon dating found in The Biblical Chronologist Volume 5, Number 1. Radiocarbon dating is based on a few relatively simple principles. The vast majority of these are C (pronounced "c twelve"), the stable isotope of carbon.

Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left.

This tendency to decay, called radioactivity, is what gives radiocarbon the name radiocarbon.

The atmosphere contains many stable carbon atoms and relatively few radiocarbon atoms.

He claimed that it was capable of dating animal, plant and human remains of fairly “recent’ origin. As they say on Star Trek, we are all carbon based units.

Laboratory research has shown that the radioactive decay of Carbon-14 occurs in a half-life of 5,73040 years through beta decay that causes the Carbon-14 to revert back to Nitrogen-14.

date of organic material - but an approximate age, usually within a range of a few years either way.
