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 slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.Very small samples (less than 300 mg) are analyzed by accelerator mass spectrometry (AMS).

Only rarely does a creationist actually find an incorrect radiometric result (Austin 1996; Rugg and Austin 1998) that has not already been revealed and discussed in the scientific literature.Radiocarbon dating is the principal method for determining the age of carbon-bearing materials from the present to about 50,000 years ago.The method takes advantage of the natural occurrence of a radioactive isotope of carbon (C in samples of ancient carbon compounds and comparing this with the amount in modern materials, it is possible to determine the time of cessation of carbon exchange with the atmosphere.Creationists seem to think that a few examples of incorrect radiometric ages invalidate all of the results of radiometric dating, but such a conclusion is illogical.The evidence against a recent creation is overwhelming.Materials suitable for radiocarbon dating include charcoal, wood and other plant matter, soils and sediments, shells, bone, carbonates, dissolved inorganic carbonate (DIC), methane and hydrocarbons, and food products.
