Problems with radio carbon dating

BASIS OF RADIOCARBON DATING Radiocarbon dating compares the amount of normal carbon with the amount of radioactive carbon in a sample.

What effect would the declining strength of the earth's magnetic field and a catastrophic worldwide flood have on radiocarbon dates?

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.

When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.

This collision is less destructive than the initial collision that produced them.

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.

As the number of protons decides the chemical nature of an atom, the atom now behaves like a carbon atom.

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.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.

...[Some authors have said] they were "not aware of a single significant disagreement" on any sample that had been dated at different labs.
