Medical equipment radiation shielding

Application scenario: The MRI equipment needs to shield against external electromagnetic interference, and the insulating surface must not pose any threat to patient safety. 

Implementation Plan: 

The conductive surface forms a shielding layer, attenuating the environmental electromagnetic waves. 

The insulating surface is in close contact with the equipment casing and complies with medical insulation standards. 

Test data: Shielding effectiveness: 75 dB (20 MHz to 1 GHz).
