Research Methods: Development of three-dimensional models, scenarios of dismantling of unstable structures and calculation of accumulated doses using program codes. Results and their novelty. Removal work on shelter structures requires new approaches to substantiate personnel safety. This is due to the fact that during the dismantling the radiation conditions will change (deteriorate) as a result of dismantling the roof elements and other structures of the Shelter object that perform the shielding function. As there is no information on ionizing radiation sources that form radiation conditions on the roof of the Shelter, it is important to predict the change in the radiation situation due to the dismantling of structures. Therefore, it is now necessary to begin work on the introduction of modern methods of computer simulation of radiation conditions, virtual spatial analysis of staff actions and calculations of its radiation. Importance of work and conclusions. Transformation of the Shelter Object into an environmentally safe system involves a considerable amount of work. A considerable amount of these works will require finding of personnel in difficult radiation conditions, which requires justification of application of effective methods of personnel protection, optimization of work processes in the places of work performance, optimization of routes of access of staff to the places of work performance, etc. Product Description popup.authors Balan Oleg V.
