When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "tooyoung" estimates of artifact age.
Scientists now realize that production of carbon14 has not been constant over the years, but has changed as the radiation from the sun has fluctuated.
the geological column and approximate ages of all the fossilbearing strata were all worked out long before anyone ever heard or thought about radioactive dating …
There are so many sources of possible error or misinterpretation in radiometric dating that most such dates are discarded and never used at all, notably whenever they disagree with the previously agreedon [index fossil] dates.” (Dr Henry Morris, creationist scientist and hydraulicist, Ph D in hydrology, geology and mathematics, Fellow of the American Association for the Advancement of Science and the American Society of Civil Engineers, former Professor of Hydraulic Engineering at Virginia Polytechnic Institute, 1974) Michael Oard, Ph. is a meteorologist and creationist scientist who writes, And when it comes to dating any individual rock today, the resulting “date” is forced to conform to predetermined evolutionist “dates” based on these imaginary 19th century indexfossil “dates”.
the global Flood of 2,348 BC) as global catastrophes reset all the radiometric/atomic “clocks” by invalidating the evolutionist’s main dating assumption that there have never been any global catastrophes.
The assumptions are similar to the assumptions used in carbon dating.Carbon14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.Any radiometric dates that show a supposedly “old” rock to be young are rejected “Few people realize that the index fossil dating system, despite its poor assumptions and many problems, is actually the primary dating tool for geologic time. In other words, radiometric dating methods are actually fit into the geological column, which was set up by [index] fossil dating over 100 years ago.”(Michael Oard, meteorologist and creationist scientist, 1984) All radiometric dating methods use this basic principle to extrapolate the age of artifacts being tested.These long time periods are computed by measuring the ratio of daughter to parent substance in a rock, and inferring an age based on this ratio.These isotopes have longer halflives and so are found in greater abundance in older fossils.Some of these other isotopes include: back to the last global catastrophe (i.e.The mathematical premise undergirding the use of these elements in radiometric dating contains the similar confounding factors that we find in carbon14 dating method.Most scientists today believe that life has existed on the earth for billions of years.Nuclear tests, nuclear reactors and the use of nuclear weapons have also changed the composition of radioisotopes in the air over the last few decades.This human nuclear activity will make precise dating of fossils from our lifetime very difficult due to contamination of the normal radioisotope composition of the earth with addition artificially produced radioactive atoms.

Carbon14, Radiometric Dating  CSI  Creation Studies Institute
Carbon14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. Carbon14 is a radioactive isotope of carbon. The halflife of carbon14 is approximately 5,730 years. The short halflife of carbon14 means it cannot be used to date fossils that are allegedly.…
Carbon Dating Definition, What is Carbon14 14C Dating?
Willard Libby developed radiocarbon dating as a method to measure radioactivity. Carbon14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C14 dating is only applicable to organic and some inorganic materials not applicable to metals. Gas proportional counting.…

Dinosaur Fossil Dating  Enchanted Learning Software
Dating a fossil in terms of approximately how many years old it is can be possible using radioisotopedating of igneous rocks found near the fossil. Unstable radioactive isotopes of elements, such as Uranium235, decay at constant, known rates over time its halflife, which is over 700 million years. An accurate estimate of.…
Nuclear Chemistry HalfLives and Radioactive Dating  dummies
Scientists look at halflife decay rates of radioactive isotopes to estimate when a particular atom might decay. A useful application of halflives is radioactive dating. This has to do with figuring out the age of ancient things. If you could watch a single atom of a radioactive isotope, U238, for example, you wouldn't be able to.…
