Radiocarbon dating is so well-known because it can be applied to nearly any organism that was living at some time.

Therefore, the amount of radioactive carbon in the system will only decrease and form Nitrogen.
In some cases, an organic sample is indeed being analyzed, but for some reason it has been contaminated by radioactive carbon or is undatable by radiocarbon methods for some other reason.
In this case determining the age of the surrounding earth or rock materials can be very helpful in determining the age of the sample.
