Probably, the three worst culprits in the home are the wireless baby monitors, the cordless phone, and the Wi-Fi, because they're on all the time, whether you're using them or not. With the phone, you can have it wired. You can still buy wired phones. You would have to have multiple ones.
When it comes to the baby monitors and the cordless phones, in Europe the baby monitors are voice activated, which means there's no radiation until the baby cries. We've been trying to get these into Canada and we haven't been successful so far.
Also in Europe, the cordless phones that you have there do not radiate until you actually use them. We had them here in Canada. They were banned by the FCC and Canada simply followed suit. It's almost impossible to get them unless you go to Europe and buy them.
When it comes to Wi-Fi, you can simply connect the ethernet connection. There's also something called a home plug, which means that you can put the information onto the electrical wires in your home and use your computer in any outlet, so you can still get Internet access anywhere in your home without having microwave radiation.
