Of over 4,000 quotations in the books this Encyclopedia is based on, only 164 statements are by creationists. One is that the carbon 14 concentration in the carbon dioxide cycle is constant.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. 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 And if it is completely out of date we just drop it.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."Muscle tissue from beneath the scalp of a mummified musk ox found in frozen muck at Fairbanks Creek, Alaska, has a radiocarbon age of 24,000, while the radiocarbon age of hair from a hind limb of the carcass is 17,200.A life span exceeding 7,000 years for a specimen of this species is doubtful.Specifically, each nucleus will lose an electron, a process which is referred to as decay.This rate of decay, thankfully, is constant, and can be easily measured in terms of ‘half-life’.

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

Half-life refers to the amount of time it takes for an object to lose exactly half of the amount of carbon (or other element) stored in it.

This half-life is very constant and will continue at the same rate forever.

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.
