X-rays help to uncover who painted a centuries-old masterpiece in Albania (Chinese Edition)

Albanian researchers have used X-rays to discover who painted a delicate, centuries-old masterpiece of Saint George, one of Christianity's most famous saints. Their methods included non-destructive testing (NDT) and non-destructive assay (NDA) involving X-rays, which are widely used to study materials and the quality of objects, from analysing cultural artefacts and biomedical samples like blood and hair, to finding cracks or cavities in oil pipes and aeroplane parts.
