Karazin popup.description2 A subject under investigation is dose field from some technical sources, first of all, in NPP. Radiation impact of these fields is determined by the design of a biological shield, with which the sources of radiation are equipped. Investigations and simulation of shield abilities of high heterogeneity objects are needed both in special measuring technique and the methods for modeling of radiation transport. For this purpose the methods can be used to form the spectrum and spatial distribution of the brensstrahlung radiation (BR). The methods for control of BR and other calculative methods for determination of detectors and radiation parameters are also suitable. A goal of this stage is working out a system for BR control, which can be used for the experimental investigation of gamma-ray transport through the heterogeneity in shield construction. For this the existed detectors have been analyzed under the conditions that have place near radioactive waste in NPP. The materials and designs have been chosenfor detector BR creation. A method of investigation is computer simulation of the processes in detectors and the analysis of the existed systems for BR measuring. A development of technique for BR parameters control is based on a modern technical achievements of this branch. On the second stage the characteristics were studied of radiation, which must been controlled as parameters of radiation impact of unit filled with radioactive waste. The main conditions were established for accelerated electrons BR control system. Also the method is developed for neutron field simulation from the cask filled with a spent nuclear fuel.
