Unreliability of Radiometric Dating and Old Age of the Earth How radiometric dating works in general : Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is called the daughter element.
2 Re: Rb-sr radiometric dating
Radiometric dating - Wikipedia 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 were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

Datazione radiometrica - Wikipedia La datazione radiometrica (o radiodatazione) è uno dei metodi per determinare l'età di oggetti antichi.Essa si basa sul raffronto tra le abbondanze osservate di un opportuno isotopo radioattivo e dei suoi prodotti di decadimento (noto il tempo di dimezzamento, ed è la principale fonte di informazioni sull'età della Terra e sulla velocità dell'evoluzione delle specie viventi).

Age of the Earth: strengths and weaknesses of dating methods It follows that uranium-lead, potassium-argon (K-Ar), and Rubidium-Strontium (Rb-Sr) decay can be used for very long time periods, whilst radiocarbon dating can only be used up to about 70,000 years.
9 Re: Rb-sr radiometric dating
Rubidium–strontium dating - Wikipedia The rubidium-strontium dating method is a radiometric dating technique used by scientists to determine the age of rocks and minerals from the quantities they contain of specific isotopes of rubidium (87 Rb) and strontium (87 Sr, 86 Sr).. Development of this process was aided by German chemists Otto Hahn and Fritz Strassmann, who later went on to discover nuclear fission in December 1938.
