Most accurate radioactive dating the field relationships, as they are called, are of primary importance and all radiometric dates are evaluated against them. while this is not absolutely 100% foolproof, comparison of several dating methods will always show whether the given date is reliable. radiometric dating is also used to date archaeological materials, including ancient artifacts. if the fossils, or the dating of the fossils, could be shown to be inaccurate, all such information would have to be rejected as unsafe. snelling, say that if the dates are scaled and also adjusted for the type of radiometric test, creationists could use the dates. basic equation of radiometric dating requires that neither the parent nuclide nor the daughter product can enter or leave the material after its formation. dating, like any other experimental discipline, is subject to a variety of errors, ranging from human errors to rare anomalies resulting from highly unusual natural circumstances. million years) gives the impression that the method is precise and reliable (box below). isotopic systems that have been exploited for radiometric dating have half-lives ranging from only about 10 years (e. as biologist kenneth miller has observed, "the consistency of [radiometric] data .' online article, mentioned above, is an excellent resource for countering claims of creationists on the reliability of geologic dating.
More Bad News for Radiometric Dating in these cases, usually the half-life of interest in radiometric dating is the longest one in the chain, which is the rate-limiting factor in the ultimate transformation of the radioactive nuclide into its stable daughter. long-range and short-range dating methods have been successfully verified by dating lavas of historically known ages over a range of several thousand years. stimulating these mineral grains using either light (optically stimulated luminescence or infrared stimulated luminescence dating) or heat (thermoluminescence dating) causes a luminescence signal to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation absorbed during burial and specific properties of the mineral. however, the appendix concludes with this qualification: ‘also, the relative ages [of the radiometric dating results] must always be consistent with the geological evidence. here is a condensed summary of these items, quoted from wiens' article [wiens2002]:Claim: radiometric dating is based on index fossils whose dates were assigned long before radioactivity was discovered. if the rock ages are not ‘known’ in advance—does radio-dating give coherent results? instead of questioning the method, he would say that the radiometric date was not recording the time that the rock solidified. finally, correlation between different isotopic dating methods may be required to confirm the age of a sample. the methods are all based on radioactive decay:Fossils may be dated by calculating the rate of decay of certain elements. in uranium–lead dating, the concordia diagram is used which also decreases the problem of nuclide loss. would generally agree with the above methods and use them in their geological work.
