Carbon 14 for dating objects
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?
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.
Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.
It follows that the older a date is, even within this 'limit', the greater are the doubts about the date's accuracy.
However, because it has too many neutrons for the number of protons it contains, it is not a stable atom.
