      Photon transport problems for high-temperature plasma require a simulation of the Compton scattering with respect to a relativistic electron motion. In such case the transport equations are characterized by a complex nature, macroscopic process cross-sections and secondary particle distribution density are expressed via integrals. To solve a photon transport equation by the Monte-Carlo method we propose a "majorizing cross-section" technique which permits to avoid the difficulties involved in evaluating cross-sections expressed by integrals.
      Some results are qiven which were obtained from a series of spectral calculations describing a 1-D system radiation, where taking into account the compton scattering on relativistic electrons affects sub- stant ially the data.
