There has been quite a lot of publicity about the research showing that using digital cordless (DECT) phones results in similar adverse health effects as using a mobile phone, including the risk of developing brain tumours [1,2]. This research seems to be scientifically sound and the evidence for problems is growing.

We have had concerned parents on the phone to us, explaining that their children do not use their mobile phones at home, due to the possible health effects, so they talk for long periods of time on the cordless phones instead.

Children, particularly teenagers, can appreciate the privacy of a cordless phone. They can shut themselves in their bedroom, the bathroom, anywhere to make their calls away from prying ears. Unfortunately, it may have unforeseen consequences that neither they nor their parents could have anticipated.

DECT phone base units transmit 24-7, even when they are not being used to make actual phone calls. We have written a much more detailed article on DECT phones in our article library.
