About one carbon nucleus in a trillion contains two extra neutrons, giving a mass of 14.

This carbon-14 is radioactive and decays with a half-life of 5730 years.

It is also called “radiocarbon” because it is unstable and radioactive relative to carbon-12 and carbon-13.

Carbon consists of 99% carbon-12, 1% carbon-13, and about one part per million carbon-14.

In principle, any material of plant or animal origin, including textiles, wood, bones and leather, can be dated by its content of carbon 14, a radioactive form of carbon in the environment that is incorporated by all living things.

Because it is radioactive, carbon 14 steadily decays into other substances.

This creates an error in the "raw" age of about 2 percent.

New research shows, however, that some estimates based on carbon may have erred by thousands of years.NOTE: Sample size required by the lab is a conservative estimate.Normal pretreatment procedures can remove 30% to 70% of the original material sent. Accelerator mass spectrometry (AMS) is a technique for direct measurement of the concentration of radioisotopes.A radiocarbon measurement can be obtained on a sample of ~0.5 mg of carbon, and measured to 40 years in uncalibrated radiocarbon age in a measurement time of 30–40 minutes on each sample.
