This means that half of the c14 has decayed by the time an organism has been dead for 5568 years, and half of the remainder has decayed by 11,136 years after death, etc.

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.

AMS technology has allowed us to date very small samples (such as seeds) that were previously undatable.

Since there are practical limits to the age range of the method, most samples must be younger than 50,000 years and older than 100 years.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.
