Gantry Room should provide radio
frequency (RF) shielding and be
constructed of non-magnetic materials.
Coordinate RF Shielding requirements
with the equipment manufacturer and
have them reviewed by a registered
health physicist.
b. Floors
Floors in offices, conference rooms and
waiting areas should be carpet with a 100
mm (4") high resilient base.
Floors in toilet rooms should be ceramic
tile with a ceramic tile base. If metal
toilet stalls are used, be certain they are
remotely located
Floors in most other spaces should be
vinyl composition tile with a 100 mm (4")
high resilient base.
Floors in MRI Gantry Rooms require a 40
mm (1-1/2") deep depression to
accommodate the RF shielding.
