The results of neutron radiography studies on convective drying of kaolin cylinders are presented. The sample shrinkage and loss of water during drying was easily observed on registered neutron radiograms. The saturation of the sample with water was estimated in terms of the neutron effective macroscopic cross-section. The results are comparable to those of gravimetric measurements and are discussed within the framework of simple theories of drying. The effect of the scattered neutrons is discussed in terms of the results of the MC simulations.
