Radioactive and relative dating
It is important to remember the difference between the two different kinds of rock.
They can provide fairly precise information about the age of a rock layer.
Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).
The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.
The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.
This restriction extends to animals that consume seafood in their diet.
In many cases, the daughter nuclide is radioactive, resulting in a decay chain.

In theory, the age of any of these minerals can be determined by: 1) counting the number of daughter isotopes in the mineral, and 2) using the known decay rate to calculate the length of time required to produce that number of daughters.
Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
However, to read any clock accurately we must know where the clock was set at the beginning.
