Radiometric dating dictionary

The use of radiometric dating was first published in 1907 by Bertram Boltwood and is now the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.Radiometrische Datierung ist eine Methode der Altersbestimmung.Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they formed.The method compares the abundance of a naturally occurring radioactive isotope within the material and the abundance of its decay products, which form at a known constant rate of decay.

Radiometrische datering is een techniek om de ouderdom van materialen te bepalen.

Pierwotną zawartość izotopu oblicza się poprzez zsumowanie produktu jego rozpadu (stałego izotopu radiogenicznego) oraz reszty nierozpadniętego izotopu promieniotwórczego.

Radiometric dating is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

21.2 RADIOMETRIC DATING Alpha decay Daughter isotope e.g.

147 Sm 143 Nd a 2 Parent isotope The discovery of radioactivity and the radiogenic decay of isotopes in the early part of the 20th century opened the way for dating rocks by ... A Half-life, the time it takes for half of the atoms in a sample of radioisotope to decay. The use of these parent-daughter pairs of isotopes to tell geologic time is called radiometric dating, or isotope dating. in which N is the number of radioactive atoms of the parent isotope at time t after the rock formed, N0 is the original number of radioactive atoms, and l is the disintegration constant.
