Bremsstrahlung losses in the high-temperature plasma thermal balance appears to be the soft X-ray radiation, which could not be directly converted into electricity, as is possible in the case of the charged particle energy or the cyclotron radiation. Bremsstrahlung is the main radiation mechanism at the reactor temperature of several keVs. For operating temperatures of the alternative fuel reactors, relativistic electron bremsstrahlung was calculated, and the approximating formulas were obtained. The radiation losses dependence on the target radius and the volumetric bremsstrahlung power of the compressible plasma on the target geometric parameters are presented, their graphs are plotted, and a comparative analysis is performed. When comparing main types of the thermonuclear systems with different magnetic configurations, conclusions were drawn on effectiveness of each of them, and the most energetically useful systems were identified.
