Basis of Radiocarbon Dating Problems with Radiocarbon Dating The Earth's Magnetic Field Table 1 Effect of Increasing Earth's Magnetic Field Removal of Carbon From the Biosphere Water Vapour Canopy Effect on Radiocarbon Dating Figure 1 Apparent Radiocarbon Dates Heartwood and Frozen Time Early Post-Flood Trees Appendix Radiocarbon Date Table HOW ACCURATE IS RADIOCARBON DATING? 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.

Surely 15,000 years of difference on a single block of soil is indeed a gross discrepancy!

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?

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.

Such enthusiasts continue to claim, incredible though it may seem, that "no gross discrepancies are apparent".

However, because it has too many neutrons for the number of protons it contains, it is not a stable atom.

Every 5,730 years, approximately half of this radioactive carbon spontaneously converts itself back into nitrogen by emitting an electron from a neutron.

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.
