And how could the excessive disagreement between the labs be called insignificant, when it has been the basis for the reappraisal of the standard error associated with each and every date in existence?
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...Usually a proton is knocked out of the nitrogen atom’s nucleus and is replaced with the neutron.The proton takes an electron with it and becomes an atom of hydrogen.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 nitrogen atom, which began with seven protons and seven neutrons, is left with only six protons and eight neutrons.As the number of protons decides the chemical nature of an atom, the atom now behaves like a carbon atom.The new version will be released when this work is completed. 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.They do so because occasional dates appear to be useful.
