ICR creationists claim that this discredits C-14 dating. Answer: It does discredit the C-14 dating of freshwater mussels, but that's about all.

The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.

So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years.

The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

and is now the principal source of information about the absolute age of rocks and other geological features, including the age of fossilized life forms or the age of the Earth itself, and can also be used to date a wide range of natural and man-made materials.

An asterisk ( * ) by a name indicates that person is not known to be a creationist. "Well authenticated dates are known only back as far as about 1600 B. "There are two basic assumptions in the radiocarbon method.

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.

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