Short summary
This paper discusses the applicability of neutron imaging techniques for probing the internal microstructure of pyritized fossil woods upon wetting and drying, two phenomena occurring in museum cabinets and endangering the specimens. We tracked the water diffusion through samples in situ and obtained information on wood pore size, network and internal structure. The differences help to understand the distinct macroscopic behaviors and determine the consequences of moisture variations in museums.
