Shielding is only part of the battle; the other part is what they're doing here: controlling incoming emissions.
Nothing can be perfectly shielded in the real world and instruments or controllers may need very long cables to connect to their respective sensors and actuators making shielding difficult.
Now add in that many of these instruments actually need to process an RF signal and so won't work if shielded, and it becomes a difficult problem to solve.
