Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporate

Ale's Stones at Kåseberga, around ten kilometres south east of Ystad, Sweden were dated back to approximately 1,400 years ago using the carbon-14 method on organic material found at the site.
Apatite crystals are widely used in fission track dating.
Uranium–lead dating

Uranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million ye
Radiometric dating
…are used in geochronology to establish the geologic time scale. Among the best-known techniques are radiocarbon dating, potassium–argon dating and uranium–lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates…
