Abstract
The design of three-dimensional screens and the methods of their application for determining the parameters of scattering particles are described. A method for measuring non-normalized moments (up to the sixth order) is proposed using three-dimensional screens. It is shown that the non-normalized moment can be measured by the attenuation of the radiation power generated by the sequence of three-dimensional screens, the number of which determines the order of the measured moment. The non-normalized moments contain information on the equivalent cross section of scattering particles and the distribution function of the particles over the cross-sectional area
