'''Radiometric dating''' is using a radioactive process to determine the age of an item.<ref>[http://pubs.usgs.gov/gip/geotime/radiometric.html Radiometric Time Scale] USGS</ref> Radiometric dating is mostly used to determine the age of rocks (though in the case of [[Radiocarbon dating]] can date wood, cloth, skeletons, and other organic material), and relies on the well-established function for exponential decay <math>F</math>_{<math>t</math>}<math>=e</math>^{<math>-kt</math>}.  Different radiometric techniques are calibrated in different ways; for example, radiocarbon dating is calibrated by dating wood that has been dated through the process of [[dendrochronology]].
