  Results of investigations of the near-horizontal muons in the range of zenith
angles of 85-95 degrees are presented. In this range, so-called "albedo" muons
(atmospheric muons scattered in the ground into the upper hemisphere) are
detected. Albedo muons are one of the main sources of the background in
neutrino experiments. Experimental data of two series of measurements conducted
at the experimental complex NEVOD-DECOR with the duration of about 30 thousand
hours "live" time are analyzed. The results of measurements of the muon flux
intensity are compared with simulation results using Monte-Carlo on the basis
of two multiple Coulomb scattering models: model of point-like nuclei and model
taking into account finite size of nuclei.
