On the one hand, radio waves intrude our living area from the outside (through signals from mobile phones, TV, radio, radar, etc.), on the other hand, they are generated "on site" (WLAN, cordless phones, baby monitors, smartphones and all devices that begin with "smart", such as smart boxes called Alexa, Siri & Co, smart meters, etc.).
We cannot reduce radiation from transmitters, but we can shield it. And by being mindful of new technologies, we are able to contribute a great deal to a healthier life.
