Research within this area is on the track of efforts to reduce EM radiation in indoor spaces where people stay advanced in the way of finding the optimal structure for the performance of building materials that have a high shielding effectiveness (protection against EM radiation). It represents a continuation of the previous research of the structures of this research group, which included finding materials and particles that would reduce EM radiation inside construction (concrete, brick) blocks. These materials would thus become the basis for the construction of residential, public and business buildings with an extremely low level of electromagnetic field strength, which is reflected in an increase in the level of population health protection (EMZ protection), especially the most sensitive groups.
