Radiocarbon dating dates back

"[d] Deep ocean deposits supposed to contain remains of most primitive life forms are dated within 40,000 years.

"[b] Only three of the 15,000 reported ages are listed as `infinite.' "[c] Some samples of coal, oil, and natural gas, all supposedly many millions of years old have radiocarbon ages of less than 50,000 years.

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.

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.

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.

Carbon-14 is a naturally occurring isotope of the element carbon.Results of carbon-14 dating are reported in radiocarbon years, and calibration is needed to convert radiocarbon years into calendar years.Uncalibrated radiocarbon measurements are usually reported in years BP where 0 (zero) BP is defined as AD 1950.Radiocarbon measurements are based on the assumption that atmospheric carbon-14 concentration has remained constant as it was in 1950 and that the half-life of carbon-14 is 5568 years.Calibration of radiocarbon results is needed to account for changes in the atmospheric concentration of carbon-14 over time.
