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).

Since the flood was accompanied by much volcanism (see Noah's Flood…, How did animals get from the Ark to isolated places? ), fossils formed in the early post-flood period would give radiocarbon ages older than they really are.

In summary, the carbon-14 method, when corrected for the effects of the flood, can give useful results, but needs to be applied carefully.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

This will make old things look older than they really are.

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.

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.
