We live in a tiny new build terrace house. We don't have any wireless stuff because we get by fine without it and I am suspicious of the safety of them as there have been a fair few scary programmes/news articles. The houses either side of ours have recently had new people move in. Both of whom seem to have wirelss, dect phones etc. DC's rooms are so small that we don't get much distance between the neighbours rooms. DD sleeps about two meters away from a wall - that's the only way a bed will fit in there and I know there is a phone point on the other side because all these houses have the same phone points. I know that there is a dect phone a few meters away from her room two because the neighbour invited us in one day.
I stupidly have googled and scared myself. Most of the websites that are anti this stuff are also selling very expensive screening/detection products.
Please tell me I am being stupid to worry about this, that your homes are the same as mine and I should definately not go off and spend money I dont have on screening stuff!!!
