Radio carbon dating bible
According to Richard Gillespie of the Australian National University (the institution at which Prof. Even very small amounts of modern contamination can be fatal for old samples” (ibid., 345).
Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.One of the biggest factors in throwing off carbon dates is the fact that nuclear testing, which began around 1950, “blasted out radiation [into the atmosphere] that scientists see clearly as a spike in the radiocarbon record” (ibid.).Most problematic in absorbing this spike in radiation has been charcoal, which scientists use frequently in their dating of ancient finds., “The older an artifact is, the less certain scientists can be about its age” (Barry 2007: 344).Chris Turney of the University of Exeter in England similarly noted: “With radiocarbon, it’s not possible to obtain absolute dates—there’s always a bit of an unknown” (ibid).As Hurley points out: Without rather special developmental work, it is not generally practicable to measure ages in excess of about twenty thousand years, because the radioactivity of the carbon becomes so slight that it is difficult to get an accurate measurement above background radiation. 108) Cosmic rays form beta radiation all the time; this is the radiation that turns N-14 to C-14 in the first place. If we extrapolate backwards in time with the proper equations, we find that the earlier the historical period, the less C-14 the atmosphere had.
If we extrapolate as far back as ten thousand years ago, we find the atmosphere would not have had any C-14 in it at all.
This article will answer several of the most common creationist attacks on carbon-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon).
Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.
Kieth and Anderson show considerable evidence that the mussels acquired much of their carbon from the limestone of the waters they lived in and from some very old humus as well.
Carbon from these sources is very low in C-14 because these sources are so old and have not been mixed with fresh carbon from the air.
Radiocarbon dating methods are frequently used in determining the ages of ancient artifacts and fossils.
