Route optimization during works in non-stationary radiation fields with obstacles

In this paper, we state the radiological protection requirements for radiation workers and describe the essence and the limits of application (realization) of one of the main radiation protection principles, the principle of optimization. We demonstrate the potential of path optimization in minimizing the dose uptake of the staff who move around and work in areas with nonstationary radiation fields. We also establish and implement an interpolation algorithm based on radial basis functions for mapping the radiation levels on premises. Finally, we describe the algorithm to determine the optimal routes, which account for obstacles based on the Dijkstra algorithm, then state the results of a computational experiment on the Uran supercomputer and discuss the performance of this algorithm.
