Radioactive isotopes are produced in the surface layers of the sample being investigated, by irradiating them with a charged particle beam of appropriate energy, intensity and irradiation time. The activated samples are installed in their normal working environment and subjected to typical wear, corrosion or erosion. The change in surface activity is then measured. The amount of wear (or corrosion or erosion) can be calculated from the activity change.
