'''Radiometric dating''' is a method of determining the age of an artifact by measuring the amount of radioactive decay that has occurred.<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 a particular form of radiometric dating - called [[Radiocarbon dating]] - can date wood, cloth, skeletons, and other organic material. It relies on the well-established function for exponential decay <math>F</math>_{<math>t</math>}<math>=e</math>^{<math>-kt</math>}.
