Studies ia a three-dimensional problem of radiation transfer and radiative heat exchange in a system consisting of bounded gray bodies separated by an absorbing and anisotropically scattering medium. Solutions are given for a generalized and three specific statements of the problem. The generalized statement is described by a system of two integral equations containing generalized characteristics of the boundary and volume radiation. With the aid of closure equations derived from the second law of thermodynamics it is shown that all statements of the problem have a unique solution. A new method is given for the numerical calculation of local characteristics of the radiation field in a continuously discrete case. New concepts are introduced, such as local and average resolving angular coefficients of radiation, attenuation methods of the medium, etc. Author
