ectricity and Magnetism An electromagnetically-shielded room is designed so that at a frequency o=10 rad s the intensity of the extermal radiation that penetrates the room is 1% of the incident radiation. If d=x10° (Om) is the conductivity of the shielding material its 87 minimum thickness should be (given that In10= 2.3) (a) 4.60 mm (b) 2.30 mm ()0.23 mm (d0.46 e
