It cannot be used to date volcanic rocks, for example.

The rate of decay of N in 5,730 years (plus or minus 40 years).

It does not give dates of millions of years and when corrected properly fits well with the biblical flood.

There are various other radiometric dating methods used today to give ages of millions or billions of years for rocks.

This also has to be corrected for.[2] Second, the ratio of C in the atmosphere at that time to be estimated, and so partial calibration of the “clock” is possible.

Accordingly, carbon dating carefully applied to items from historical times can be useful.

That is, they take up less than would be expected and so they test older than they really are.

Furthermore, different types of plants discriminate differently.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.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.Unless this effect (which is additional to the magnetic field issue just discussed) were corrected for, carbon dating of fossils formed in the flood would give ages much older than the true ages.
