Optimization of Biological Shield Configurations for the Facility Analyzing Elemental Composition of Rocks by the GEANT4 Toolkit

Resumo

A method for optimizing the configuration of the shield from ionizing radiation for the facility analyzing the elemental composition of rocks, which is installed at the Department of Applied Nuclear Physics of the National Research Nuclear University MEPhI. Optimization is performed by the methods of mathematical simulation of the distribution of the equivalent dose rate generated during the facility operation. The Geant4 toolkit is used as the simulation environment. The influence of construction elements of the facility and the objects at the laboratory on the dose value is analyzed. In addition, the simulation results are validated by comparison to the data of dosimetry measurements. In conclusion, the possibility of using the algorithm presented for the design of biological shields from ionizing radiation sources is shown.
