ABSTRACT
Abstract A model non-magnetic chamber was built with concrete reinforced with CFRP. The magnetic characteristics as an active shielding room for measuring the magnetic fields of brains were tested and evaluated. As a result, the response magnetic fields from CFRP is very small to compare with steel reinforcement. In addition, the response magnetism gradients is less than 10 6 of the applied magnetic fields. Therefore, CFRP reinforcement can be used in medical facilities where high degrees of non-magnetism are required for SQUID in active shielding.
