Derivation of an effective algorithm for the fast estimation of cloudshine doses/dose rates induced by a large mixture of radionuclides discharged into the atmosphere. Special modification of the classical Gaussian plume approach is proposed for approximation of the near-field dispersion problem. . An efficient approach is introduced for treatment of a wide range of energetic spectrum of the emitted photons when the usual multi-nuclide approach is replaced by a new multi-group scheme. The proposed procedure is predetermined such as a proper tool for online data assimilation analysis in the near-field areas.
