Digitally enhanced cordless telephones - Dects - are the main source of radiation at home where people spend a lot of time, causing frequent headaches, fatigue, heart palpitations, concentration and sleep problems, according to a recent survey by the Dutch Electrohypersensitivity Foundation. 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. ''The risks are the same as for mobiles, but they haven't been studied because researchers thought the Dect operated like a landline,'' Daily Mail quoted cancer specialist Lennart Hardell from the University Hospital, Sweden as saying.
''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,'' stated Prof Hardell.
Its more harmful as the base station is powering up 24-hours-a-day and the handset is picking up and sending signals whenever it's held to the head, with the signal travelling through walls and ceilings too.
