Abstract: Spectral energy fluxes emerging from the surface of an axially symmetric column of inhomogeneous cesium high-pressure plasma have been calculated by direct integration of the radiation-transport equation. It is shown that, at a specified plasma temperature on the axis, irrespective of the radiation -formation mechanism and the radial distribution of the plasma parameters, the maximum energy fluxes arise when the radial optical thickness $\tau_R$ of the plasma column is close to unity. The asymptotic $\tau_R$ value, at which the discharge column radiation is the largest part of the Planck radiation, has been found.
