The carbon-14 decays with its half-life of 5,700 years, while the amount of carbon-12 remains constant in the sample.

However, the principle of carbon-14 dating applies to other isotopes as well.

Potassium-40 is another radioactive element naturally found in your body and has a half-life of 1.3 billion years.

It turns out that the origin and concentration of C in fossil fuels is important to the physics community because of its relevance for detection of solar neutrinos.

Apparently one of the new neutrino detectors, the Borexino detector in Italy, works by detecting tiny flashes of visible light produced by neutrinos passing through a huge subterranean vat of "scintillation fluid".

The Problem: Accelerator mass spectrometry (AMS), a sensitive radiometric dating technique, is in some cases finding trace amounts of radioactive carbon-14 in coal deposits, amounts that seem to indicate an age of around 40,000 years.

Though this result is still too old to fit into any young-earth creationist chronology, it would also seem to represent a problem for the established geologic timescale, as conventional thought holds that coal deposits were largely if not entirely formed during the Carboniferous period approximately 300 million years ago.

Radiocarbon dating relies on the amount of radiocarbon, or carbon-14, remaining in an object to determine its approximate age.

Radiocarbon is a radioactive form of carbon that's created when nitrogen reacts with cosmic rays in the upper atmosphere.

I picked him to bother with my emails because he had recently written some nice review articles about the AMS technique in the Radiocarbon journal.
