I might soon have to spend some hours in a classroom with Wi-Fi - and possibly students that connect wirelessly to the router. I wonder if this shirt would reduce the radiation on me in such a classroom...?
A - The RF protection clothes will help, to some extent, depending on the type of fabric, on the location of the RF source and on the level and type of the person sensitivities. If there is only one WIFI router and if it is installed on the ceiling or upper part of the wall, then an RF Protection Hat and an RF Protection Jacket or an RF Protection Shirt will help. If the class is full with cellphones, tablets and wireless laptops, then it is more hard to say. The idea should be to avoid such environments.
