[en] The determination of heavy impurities concentration and their distribution according to a degree of ionization is an important problem for Tokamak devices. There are ions with the charge up to or over 10. Such ion radiate large massives of adjacent lines wich are satellites of the resonance line of the-live ion and group into pronounced maximums. Integral intensities of these maximums can be used for the diagnosis of impurity concentrations and their distribution according to a degree of ionization. Excitation channels of 2p-1s heavy impurities transition in a high-temperature discharged plasma are discussed. The form of iron and chromium X-ray K-lines formed by transitions in multichargd ions of different ionization ratio is calculated. The influence of such effects of non-equilibrium as escape of electrons, diffusion and recharging on neutral hydrogen atoms is investigated. Calculation results are compared with the experiments at Tokamak-type devices
