Cordless phones are now the standard in most households and, like mobile handsets, they emit microwave radiation - from both the base unit and the handset itself - that is alleged to cause brain tumours, breast cancer, dementia, DNA damage, concentration problems, memory loss, mood and behavioural changes and fertility problems.

What you can do:
Install a landline telephone that plugs into the wall-socket and remains attached to it by a wire and try to use it for most calls. If you can’t do without a cordless phone, buy an analogue model, as their base units emit radiation only when the phone is active.
Avoid the newer digital phones (Digital Enhanced Cordless Telephones, or DECTs) as their base units emit radiation 24 hours a day, whether you are using them or not.
