[en] The results of calculations of the masses of the radial excited mesons in the framework of the MIT bag model are presented. Corrections to the mass which comes from ''magnetic'' moment interaction are discussed. The model predictions for the masses of the first radial excited strange mesons are given. Among experimentally observed particles there are only two which can be identified as radial excitation in light mesons. They are rho' (1250) and rho' (1600). The model predicts two particles with masses of 1550 MeV and 1610 MeV, which corresponds to the first radial excitation of rho-type
