To use radioactive dating for a substance you must know the substance's


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.

The beautiful scenery in Washington state hides a darker history. It was formed by a gigantic volcanic eruption that cooled the planet.

Radiometric dating methods are used to establish the geological time scale . [3] Among the best-known techniques are radiocarbon dating , potassium-argon dating and uranium-lead dating .
