Abstract

Neutron imaging techniques are non-destructive tools that can help to understand the processes involved in manufacturing and restoration of cultural heritage artefacts. The interaction of neutrons with matter is markedly different from the interaction of other types of radiation, enhancing features where light elements are involved. Imaging of relative levels of neutron absorption is based on photography of scintillations produced in a ZnS screen doped with LiF, where Li is used as a neutron to charged particle converter. In this work we present studies made in the Portuguese Research Reactor applied to the characterization of restorations with resin, absorption of natural oils, and water retention.
