Physics in archaeology

A brief account is given of the application of physical methods in archaeology. The applications are grouped under three main headings: the location, analysis and dating of finds. Under location the resistivity, magnetic and electromagnetic survey methods are included and, for use in locating cavities in walls, the sonic survey and neutron back-scattering survey are described. The analytic techniques include x-ray fluorescence, neutron activation and β-ray back scattering. Finally, under dating, the radiocarbon, thermo-remanent magnetism and thermoluminescent techniques are described.
