Professor Willard Libby produced the first radiocarbon dates in and was later awarded the Nobel Prize for his efforts. Well over forty different radiometric dating methods are in use, and a number of non-radiogenic methods not even mentioned here. Consider the list of all known radioactive isotopes with half-lives of at least one million years but less than one quadrillion years, and which are not themselves produced by any natural process such as radioactive decay or cosmic ray bombardment [ Nuclides ]: A recent survey of the rubidium-strontium method found only about 30 cases, out of tens of thousands of published results, where a date determined using the proper procedures was subsequently found to be in error. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature. Such contamination can occur if a sample is exposed to carbon compounds in exhaust gasses produced by factories and motor vehicles burning fossil fuels such as coal or gasoline. Over time 14C decays to nitrogen 14N. Anomalies As noted above, creationists make great hay out of "anomalies" in radiometric dating. The decay rates are poorly known, so the dates are inaccurate. When a fossil is sandwiched between two such volcanic deposits, their potassium-argon dates provide a minimum and maximum age.
