The results of application of gamma-spectrometric technologies for carborne radiation survey in the NPP vicinity are presented [1-7]. The methods presented were developed at Nuclear Radiation Monitoring Laboratory, Moscow Engineering Physics Institute. The methods presented were developed at Nuclear Radiation Monitoring Laboratory, Moscow Engineering Physics Institute. The principal feature of the methods developed is that no prior information about any gamma-emitting source characteristics (radionuclide combination, etc.) and radiation background data are to be used for sources localization and identification. The methods can be applied when the car is moving and under conditions of strong spatial variations in the radiation background. The gamma-spectrometric methods developed are fundamentally ahead of the dosimetric ones in terms of sensitivity and information content. The special methods for gamma-spectrometric data processing and analyzing were developed and implemented in the SMS Na Avto software and SAS Na Avto software.
