The Kullander report of the 6 month used ash stated that it "contains" 10% Cu and 11% Fe. It is not clear by what analysis that assessment was made, but it was likely EDAX (Energy Dispersive X-ray Spectral analysis), normally made via SEM. Such analysis is a surface measurement. In the case of dense materials like Ni and Cu, the penetration depth for most of the X-ray spectra is only about 100 nanometers. So Kullander was probably reporting on the surface concentration.
