PROBLEMS WITH RADIOCARBON DATING During the last 30 years, a new method of determining C14/C12 ratios has been developed.It uses accelerator mass spectrometry to determine the amounts of C14 and C12 in a small sample which is vaporised in the test.The carbon dioxide is absorbed by plants, and the plants are eaten by animals, thus contaminating every living thing on earth with radioactive carbon. As time passes, the C14 in its tissues is converted back into nitrogen.If we know what the original ratios of C14 to C12 were in the organism when it died, and if we know that the sample has not been contaminated by contact with other carbon since its death, we should be able to calculate when it died by its C14 to C12 ratio.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.It is the supposed accuracy of the new method that allows measurements sensitive enough to date objects claimed to be more than twenty or thirty thousand years old.A recent test by the British Science and Engineering Research Council has shown that the accuracy of the new technique is greatly overrated.

The implications of pervasive contamination and ancient variations in carbon-14 levels are steadfastly ignored by those who base their argument upon the dates....[Some authors have said] they were "not aware of a single significant disagreement" on any sample that had been dated at different labs.Such enthusiasts continue to claim, incredible though it may seem, that "no gross discrepancies are apparent".Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.Cosmic rays are positively charged atoms moving at enormous speeds.
