Numerical models for analysis and adjustment of magnetic field in medical centers. I. Simulation of geomagnetic field disturbances

https://doi.org/10.21638/11701/spbu10.2022.306Abstract
The study investigates possible disturbances of the Earth’s geomagnetic field associated with ferromagnetic structures of clinical buildings. An original methodology has been applied for 3D field mapping of hospital areas in the Senegalese Radiotherapy (RT) Centre. The RT unit will be located in a bunker with thick steel walls to ensure safety of patients and staff. Steel reinforcement will provide the shielding effect lowering the field level in the therapy room. A detailed numerical model has been created to simulate an expected field map in the RT bunker. The model reflects the actual geometry and reinforcement pattern of the building as well as adopted national standards for hypomagnetic field environment. The field maps generated with the EM codes KLONDIKE and KOMPOT form a basis for validation in comparative computations with the other codes (COMSOL Multiphysics, etc).
