Radiometric dating is a method of determining the age of an artifact by assuming that on average decay rates have been constant see below for the flaws in that assumption and measuring the amount of radioactive decay that has occurred.
Because radiometric dating fails to satisfy standards of testability and falsifiability , claims based on radiometric dating may fail to qualify under the Daubert standard for court-admissible scientific evidence. Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks.
Therefore, in any material containing a radioactive nuclide, the proportion of the original nuclide to its decay products changes in a predictable way as the original nuclide decays over time.
This predictability allows the relative abundances of related nuclides to be used as a clock to measure the time it takes for the parent atom to decay into the daughter atom s. Calculate the mass of Cs that will be left after 90 years.

Search for: Key Points The best-known techniques for radioactive dating are radiocarbon dating, potassium-argon dating and uranium-lead dating.
This technique may allow dating the age of formation of the crystal, and also that of any overgrowths which may have formed as growth rings throughout that crystals history through crustal recycling.
It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and it can be used to date a wide range of natural and man-made materials.
