Few archaeologists who have concerned themselves with absolute chronology are innocent of having sometimes applied this method. ." In spite of its flaws, it is far more accurate than radiodating. In other words, the whole picture is now consistent with the non-equilibrium model. C., there are no suitable [historically dateable] materials for calibration purposes, and so it is not possible to trace the curve back further in time . "Conventional C-14 calibration has the effect of `stretching out' radiocarbon time and slowing down, for example, the rate of man's cultural development. And if it is completely out of date we just drop it. Before this, the atmospheric activity is observed to decrease in such a way that, by about 2000 B. Clearly, the trend for older samples to have progressively lower delta % levels is observed.Wood fragments from the gravel in which the remains were buried have a radiocarbon age of approximately 5,000 years.The bones would not have survived 6,000 solar years of exposure, nor could they be expected to remain in an articulate relationship during erosion and reburial by natural processes."A mastodon skeleton, found at Ferguson Farm near Tupperville, Ontario, provided a radiocarbon age of 8,900 for the collagen fraction of bones and a radiocarbon age of 6,200 for high organic-content mud from within the skull cavities. Flint, "Radiocarbon Dating," in Science, February 8, 1957, p. Only if all the factors producing C-14 in living tissue are unchanged, can past radiodating results be reliable "An earlier increase in neutrino levels] must have had the peculiar characteristic of resetting all our atomic clocks.It is unlikely that this skeleton could have survived exposure for 2,700 solar years before emplacement in peat."—Robert H. Waterbolk, "Groningen Radiocarbon Dates III," in Science, December 19, 1958, p. "Local variation, especially in [marine] shells, can be highly significant . The most significant problem is that of biological alteration of materials in the soil. To produce an error of 50 percent in the age of a 10,000 year old specimen would require the replacement of more than 25 percent of the carbon atoms. This would knock our C-14, potassium-argon, and uranium-lead dating measurements into a cocked hat! Arnold and I had was that our advisors informed us that history extended back only 5,000 years . You read books and find statements that such and such a society or archaeological site is [said to be] 20,000 years old. Olsson introduce their report with these words: "C-14 dating was being discussed at a symposium on the prehistory of the Nile Valley.At normal [present] growth rates, between 500-2,000 solar years would be required for the development of an eighteen-inch peat layer.

You will have a better understanding of the following statements by scientists if you will also read the web page, . The other is that the cosmic ray flux has been essentially constant—at least on a scale of centuries."—*J. Kulp, "The Carbon 14 Method of Age Determination," in Scientific Monthly, November 1952, p. "Hair from the Chekurovka mammoth that was found in the Lena River delta region of Russia has a radiocarbon age of 26,000 [years] while the radiocarbon age of peat only eighteen inches above the carcass is 5,610.

von Fange, "Time Upside Down," in Creation Research Society Quarterly, June 1974, p. "Although it was hailed as the answer to the prehistorian's prayer when it was first announced, there has been increasing disillusion with the [radiocarbon] method because of the chronological uncertainties—in some cases absurdities—that would follow a strict adherence to published C-14 dates . What bids to become a classic example of `C-14 irresponsibility' is the 6,000 year spread of 11 determinations for Jarmo, a prehistoric village in northeastern Iraq which, on the basis of all archeological evidence, was not occupied for more than 500 consecutive years."—*C. Reed, "Animal Domestication in the Prehistoric Near East," in Science, 130 (1959), p. "A survey of the 15,000 radiocarbon dates published through the year 1969 in the publication, Radiocarbon, revealed the following significant facts: "[a] Of the dates of 9,671 specimens of trees, animals, and man, only 1,146 or about 12 percent have radiocarbon ages greater than 12,530 years.

By contrast, this revised approach has the effect of `compressing' radiocarbon time,' and speeding up the rate of man's cultural development."—Erich A.

The level of atmospheric Radiometric dating in general, of course, poses a huge problem for people who believe that the universe is 6000-odd years old.

A favorite tactic of Young-Earthers involves citing studies which show trace amounts of Indeed, this results from a unique decay mode known as "cluster decay" where a given isotope emits a particle heavier than an alpha particle (radium-226 is an example.) This fact is extremely inconvenient to young-earthers, and creationist literature, accordingly, usually does not mention it.
