The barrel represents the earth's atmosphere in which the carbon-14 accumulates.The water leaking out the sides of the barrel represents the loss (mainly by radioactive decay) of the atmosphere's supply of carbon-14.The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an "isochron") by means of standard linear regression methods of statistics.The following material has been taken from a sheet entitled Several Faulty Assumptions Are Used in all Radiometric Dating Methods.Carbon 14 is used for this example:, which was put out by Dr. is presently only 1/3 of the way to an equilibrium value which will be reached in 30,000 years. Knowing how faulty creationist "facts" can be, let's do a little research of our own.There are about two dozen decay pairs used for dating.
When the carbon dioxide, containing C14 as well as stable C12 and C13, is taken in by plants it is no longer exposed to the intense cosmic ray bombardment in the upper atmosphere, so the carbon 14 isotope decays without being replenished.In a related article on geologic ages (Ages), we presented a chart with the various geologic eras and their ages.In a separate article (Radiometric dating), we sketched in some technical detail how these dates are calculated using radiometric dating techniques.other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.
Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.
