A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will spontaneously change into a different nuclide by radioactive decay.

The decay may happen by emission of particles (usually electrons (beta decay), positrons or alpha particles) or by spontaneous nuclear fission, and electron capture.

it is produced solely by a process of radioactive decay after the formation of the mineral.

Thus the current ratio of lead to uranium in the mineral can be used to determine its age.

It can be used to date rocks that formed from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range.

The dating method is usually performed on the mineral zircon.

How radiometric dating works in general Why methods in general are inaccurate Why K-Ar dating is inaccurate The branching ratio problem How Errors Can Account for the Observed Dates Why older dates would be found lower in the geologic column especially for K-Ar dating Do different methods agree with each other on the geologic column?

Possible other sources of correlation Anomalies of radiometric dating Why a low anomaly percentage is meaningless The biostrategraphic limits issue Preponderance of K-Ar dating Excuses for anomalies Need for a double-blind test Possible changes in the decay rate Isochrons Atlantic sea floor dating Dating Meteorites Conclusion Gentry's radiohaloes in coalified wood Carbon 14 dating Tree ring chronologies Coral dating Varves Growth of coral reefs Evidence for catastrophe in the geologic column Rates of erosion Reliability of creationist sources Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium.

This transformation is accomplished by the emission of particles such as electrons (known as beta decay) or alpha particles.

It may be used to date a wide range of natural and man-made materials.

Fossils may be dated by taking samples of rocks from above and below the fossil's original position.

Various methods exist differing in accuracy, cost and applicable time scale.

Additionally, elements may exist in different isotopes, with each isotope of an element differing only in the number of neutrons in the nucleus.

If these dates are correct, this calls the Biblical account of a recent creation of life into question.
