The article presents rated data for analysis of efficiency of concrete shielding against slant penetration of bremsstrahlung of 5.0 MeV electrons with due account of the angle-energy distributions of radiation from targets. Initial angle-energy distributions for aluminum, iron and tungsten targets have been obtained by direct Monte-Carlo simulation of interactions with the help of the program SCIN_PC. Then the value of air kerma was computed analytically and kerma attenuation by concrete shielding was estimated with application of available reference information. Kerma values at checkpoints behind the concrete shielding of the existing bench, which is intended mainly for electron accelerators of smaller energy, have been estimated. Bench operating restrictions for adjustment works with the ILU-10 accelerator have been formulated
