Decay & Half Life Plexus-NSD

The discovery of the radioactive properties of uranium in by Henri Becquerel subsequently revolutionized the way scientists measured the age of artifacts and supported the theory that Earth was considerably older than what some scientists believed. However, one of the most widely used and accepted method is radioactive dating. All radioactive dating is based on the fact that a radioactive substance, through its characteristic disintegration, eventually transmutes into a stable nuclide. When the rate of decay of a radioactive substance is known, the age of a specimen can be determined from the relative proportions of the remaining radioactive material and the product of its decay. In , the American chemist Bertram Boltwood demonstrated that he could determine the age of a rock containing uranium and thereby proved to the scientific community that radioactive dating was a reliable method.

Radioactive Decay: A Sweet Simulation of a Half-life

In geochronology …significantly since the development of radiometric dating, a method of age determination based on the principle that radioactive atoms in geologic materials decay at constant, known rates to daughter atoms. Radiometric dating has provided not only a means of numerically quantifying geologic time but also a tool for determining the… In Devonian Period: Occurrence and distribution of Devonian deposits Radiometric dating of granitic intrusions associated with the Caledonian orogeny yields ages between about million and million years. The igneous activity that produced such intrusions constituted the final stages of subduction and obduction that is, overthrusting of the edge of one lithospheric plate… In geochronology: Early attempts at calculating the age of the Earth …the discovery of naturally occurring radioactivity by the French physicist Henri Becquerel in and the subsequent recognition by his colleagues, Marie and Pierre Curie, that compounds of radium which occur in uranium minerals produce heat.

Measurement of N, the number of 14 C atoms currently in the sample, allows the calculation of t, the age of the sample, using the equation above. The above calculations make several assumptions, such as that the level of 14 C in the atmosphere has remained constant over time. The calculations involve several steps and include an intermediate value called the "radiocarbon age", which is the age in "radiocarbon years" of the sample: Radiocarbon ages are still calculated using this half-life, and are known as "Conventional Radiocarbon Age". Since the calibration curve IntCal also reports past atmospheric 14 C concentration using this conventional age, any conventional ages calibrated against the IntCal curve will produce a correct calibrated age.
