       The direct integration method for calculation of spectral energy losses by radiation Wλ and a radial energy flux of radiation Fλ is described sequentially for axial-symmetric LTE plasma of pulse high pressure cesium discharge. It is shown that the maximal Wλ and Fλ values are reached in that part of a spectrum, where a radial optical thickness of plasma column τR ~ 1. Comparison with calculations in a diffusion approximation is executed. It is shown that the results of calculations differ no more than for 25% in all considered modes of discharge.
