Thick steel plates are used for shielding massive MRIs. Cyclotrons use lead bricks and thick concrete for shielding. Second floor concrete slabs can be stiffened for sensitive equipment but it’s costly. Understand maintenance requirements for MRIs. Annual field replacement and cryo renewal can be necessary, depending on use of equipment.
