Efficiency of hybrid monitoring of air radiation contamination

The idea of hybrid monitoring of pollution transport in atmosphere including the united measuring and model monitoring was suggested earlier. An attempt of quantitative estimation of the efficiency of the hybrid monitoring of NPP effluent transport in the atmosphere is made. A method for calculation of errors in estimations of wind velocity and plume axis position for all its points is suggested, and numerical estimates for the hybrid monitoring efficiency are given. The results obtained were used in projects of automated systems for NPP environment radiation monitoring
