The shielding effectiveness of building material – brick filled with mineral wool

摘要

Initially, people were exposed to radiation originating from Earth and the cosmos, a rapid increase in artificial sources of electromagnetic radiation began at the end of the 20th century. This paper deals with research in electromagnetic shielding field. Experiment in this paper is focused on measurement of shielding effectiveness. Measured object was brick filled with mineral wool. Measurements were made for filled bricks with a thickness of 30 cm, 38 cm, 44 cm and 50 cm. The measurement shows that the shielding effectiveness increases with the increasing thickness of the material.
