Spontaneous breakdown or decay of atomic nuclei, termed radioactive decay, is the basis for all radiometric dating methods. Radioactivity was discovered in 1896 by French physicist Henri Becquerel. By 1907 study of the decay products of uranium (lead and intermediate radioactive elements that decay to lead) demonstrated to B. B. Boltwood that the lead/uranium ratio in uranium minerals increased with geologic age and might provide a geological dating tool.

U half-life is always ultimately determined from the determined. While uranium-235 contains 92 protons , 143 neutrons. Principles of radiometric dating. U atoms that decay over given time periods are directly counted.
