• This paper deals theoretically with the steady radiative teat transfer from a point source in a uniform flow of an optically thick gas. The gas is assuned to be grey, inviscid, non-heat conducting and the radiation field to be in local thermodynamic equilibrium. The Mach number is assumber to be small and the intensity of the heat source is assumed to be weak. Thus the analysis is based on the linearized equations. The point heat source is considered as a limit of a black sphere whose radius tends to zero and whose temperature tends to infniy to give a finie effect to the radiation field. A method of solution is developed in which the diffusive asymptotic field and the radiation region adjacent to the heat source are considered successively. The spherical symmetric radiation region is studied in detail. Numerical discussions are also made of the distribution of the temperarature in the radiation region.
