Service program package for calculating the radiation conditions at NPP environment

The algorithms underlying the complex of programs designed for calculating the distribution of radioactive effluent near the Earth concentrations at NPP environment are described. The programs permit to calculate a single specific concentration of effluents blown out from the point source located at any height within the limits from the ground upto several hundreds metres and ann average annual effluent concentration near the Earth. The complex comprises special programs for calculating the effluent jet rise and NPP cooling tower torch. The programs are written in the FORTRAN language
