1. what type of insulation/material if a box is made of will protect in 100% effectiveness it's content from all type of waves/signals/energies that exist(anything you can think of or imagine) and that comes in contact with it?
2. how do I measure/detect all type of waves/signals(the exact types) that come in contact with that box and figure out their source?
3. are some signals/waves/energies impossible to be blocked no matter what material we put?
