Carbon 14 blank ams radiocarbon dating
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.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...However, because it has too many neutrons for the number of protons it contains, it is not a stable atom.
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.
The ions produced are forced into a magnetic field where the different mass of the carbon isotopes causes a different deflection, allowing the quantity of each isotope to be measured.
This method is claimed to be more accurate than the older and slower method of counting the number of radioactive decay emissions from a quite large sample.
...[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".
