The strength of the Earth's magnetic field affects the amount of cosmic rays entering the atmosphere.

A stronger magnetic field deflects more cosmic rays away from the Earth.

These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.

For example, potassium-40 decays to argon-40; uranium-238 decays to lead-206 via other elements like radium; uranium-235 decays to lead-207; rubidium-87 decays to strontium-87; etc.

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.When a “date” differs from that expected, researchers readily invent excuses for rejecting the result.The common application of such posterior reasoning shows that radiometric dating has serious problems.To derive ages from such measurements, unprovable assumptions have to be made such as: There is plenty of evidence that the radioisotope dating systems are not the infallible techniques many think, and that they are not measuring millions of years. For example, deeper rocks often tend to give older “ages.” Creationists agree that the deeper rocks are generally older, but not by millions of years.Geologist John Woodmorappe, in his devastating critique of radioactive dating,[8] points out that there are other large-scale trends in the rocks that have nothing to do with radioactive decay.

Also, the Genesis flood would have greatly upset the carbon balance.
