Visualization of water permeation into granite by neutron radiography

A. Cho, M. Matsubayashi and S. Hasegawa


Neutron radiography experiments were performed to visualize water permeation into granite. Four types of cubic granite samples, 40 mm in length, were placed on a wet sponge, and neutron radiographs were taken every 10 min. The developments of water permeation front could be observed by subtracting the brightness of the two consecutive images.
