K–Ar dating was used to calibrate the geomagnetic polarity time scale.Thermoluminescence testing also dates items to the last time they were heated.For example, techniques based on isotopes with half lives in the thousands of years, such as Carbon-14, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.

Because of these and other factors, Thermoluminescence is at the most about 15% accurate.Argon, a noble gas, is not commonly incorporated into such samples except when produced in situ through radioactive decay.The date measured reveals the last time that the object was heated past the closure temperature at which the trapped argon can escape the lattice.This is a radiometric technique since it is based on radioactive decay.
