Fig. 5From: Multi-modal tomography to assess dechlorination treatments of iron-based archaeological artifactsHistogram of linear attenuation coefficients for nail B before and after treatment. The histogram a shows a clear difference for higher attenuation values, corresponding to chloride-based material. The X-ray histogram shows no clear difference. a Neutron linear attenuation coefficient histogram, b X-ray linear attenuation coefficient histogramBack to article page
