Radiometric dating is also used to date archaeological materials, including ancient artifacts. If a material that selectively rejects the daughter nuclide is heated, any daughter nuclides that have been accumulated over time will be lost through diffusionsetting the isotopic "clock" to zero. One of the most widely used is potassium—argon dating K—Ar dating.

That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide. Some scientists prefer the terms chronometric or calendar datingas use of the dating methods accuracy "absolute" implies an unwarranted certainty of accuracy.
All of the current dating methods are going through refinement. Fluorine absorption Nitrogen dating Obsidian hydration Seriation Stratigraphy.
The carbon ends up as a trace component in atmospheric carbon dioxide CO 2. Our geologist would be very happy with this result.
