Description

let US summarize the most important achievements and conclusions of the thesis: - the conditions necessary for optimization of the neutron radiography investigation of the process of water migration in several porous technical materials and for limiting the image-degrading impact of scattered neutrons have been established. optimal object-screen distance has been experimentally determined to be about 2 cm (chapter 4). the effective macroscopic cross section of neutron attenuation by water has been confirmed to be 3.34 +0.01 cm-1 in accord with earlier experimental findings.- first steps of implementation the monte Carlo simulation of the neutron scattering in systems investigated have been done-the msn algorithm has been elaborated and verified . the monte Carlo simulation of the neutron interaction process with the simulated water plates and water step-wedge was carried out to provide a qualitative understanding of the experimental data
