Their results were 'two to three times less accurate than implied by the range of error they stated.' They thought the variations might have been caused by poor laboratory standards allowing contamination of the samples.Some scientists believe the problem runs far deeper than this, as the following quote shows: In the light of what is known about the radiocarbon method and the way it is used, it is truly astonishing that many authors will cite agreeable determinations as "proof" for their beliefs...Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.

Thirty-one of the labs gave results that the British group called unsatisfactory.

The normal carbon atom has six protons and six neutrons in its nucleus, giving a total atomic mass of 12.Radiocarbon dating is frequently used to date ancient human settlements or tools. It is a stable atom that will not change its atomic mass under normal circumstances.This limit is currently accepted by nearly all radiocarbon dating practitioners.It follows that the older a date is, even within this 'limit', the greater are the doubts about the date's accuracy.

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