Magnetically shielded room

The first one of the two magnetically shielded rooms of the BioMag Laboratory (both built by ETS Lindgren, Euroshield Ltd.)


The site was selected on the basis of noise level (about 1 nT/(root Hz) at 2--5 Hz) and distance to Cardiology and Neurology Departments. The required shielding factor (30--80 dB from 0.1 to 100 Hz) was exceeded by 10--20 dB.

The MCG is used in the room of the figure. There is a ramp mechanism for wheeled bed. The room is illuminated by lamps on the roof of the cabinet via optic fibers. There are 15-inch holes for stimuli and cardiac monitor
