The age of artefacts radioactive dating
Because of the somewhat short half-life of 14C, radiocarbon dating is not applicable to samples with ages greater than about 50,000 years, because the remaining concentration would be too small for accurate measurement.Thermoluminescence dating: this method is associated with the effect of the high energy radiation emitted as a result of the decay or radioactive impurities.
Prior to the development of radiocarbon dating, it was difficult to tell when an archaeological artifact came from.This is called Therefore the characteristic property of the radioisotope, namely its radioactivity can act as a tag or label, which permits the fate of the element or its compound containing this element to be traced through a series of chemical or physical changes.Some of the application of tracer techniques are discussed below.It also allows the estimation of the age of geological samples using the decay of long lived nuclides.All radioactive decays follow first order kinetics.
