"These phones operate using the same technology as wi-fi computer systems and mobile phones - with the base station acting like a miniature mobile phone mast.
A recent survey by the Dutch Electrohypersensitivity Foundation has found that digitally enhanced cordless telephones - Dects - are the main source of radiation in homes that have them.
The researchers claimed that they frequently cause headaches, fatigue, heart palpitations and concentration and sleep problems.
According to cancer specialist Professor Lennart Hardell from the University Hospital, in Orebro, Sweden: "The risks are the same as for mobiles, but they haven't been studied because researchers thought the Dect operated like a landline."
One of the few scientists to have included cordless phones in his studies, Professor Hardell's research suggests that habitual users have a three-fold risk of acoustic neuroma (a benign tumour between the ear and brain) and a four-fold risk of a malignant brain tumour."
