Lead Isotopes

The use of lead isotopes in archaeology, initially as a technique to identify the source of the metal (primarily silver and copper) used for artifacts, but lately on a wider range of material and even human dental enamel, has gone through a typical cycle of enthusiastic adoption followed by a slower reevaluation of the best ways in which to deploy the technique.
