The approach was a sensation when it was introduced.

The chemist who developed carbon dating, Willard Libby, won the Nobel Prize for his work.

In order to ascertain the ages of samples which were formed in equilibrium with different reservoirs to these materials, it is necessary to provide an age correction.

Implicit in the Conventional Radiocarbon Age BP is the fact that it is not adjusted for this correction.

By the year 2100, the atmosphere will have a radiocarbon age of 2,000 years old. If Graven's calculations are correct, carbon dating as we know it today will no longer be reliable by the year 2030.

Which means scientists won’t be able to use carbon dating to distinguish between new materials and artifacts that are hundreds or thousands of years old.

Samples for dating need to be converted into a form suitable for measuring the content; this can mean conversion to gaseous, liquid, or solid form, depending on the measurement technique to be used.

Cosmic rays are positively charged atoms moving at enormous speeds.

Samples used for radiocarbon dating must be handled carefully to avoid contamination.

Not all material can be dated by this method; only samples containing organic matter can be tested: the date found will be the date of death of the plants or animals from which the sample originally came.

The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.

This atom is not stable, and will break down, releasing nuclear energy in the process.
