This can reduce the problem of contamination. Multiple papers have been published both supporting and opposing the criticism. Physical Review. Radiocarbon dating. It will therefore have the same proportion of 14 C as the atmosphere, or in the case of marine animals or plants, with the ocean.
While the moment in time at which a particular nucleus decays is unpredictable, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-lifeusually given in units of years when discussing dating techniques.
Climatic geomorphology Denudation chronology Stratigraphy Paleontology Paleoclimatology Paleogeography. The development of radiocarbon dating has had a profound impact on archaeology. Memoirs of the Society for American Archaeology 8: Earth and Planetary Science Letters. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide.
