The critical issue is how much exposure at what intensity equates to risk? Microwave radiation is measured in units known as microtesla (µT). In some countries, exposure is strictly limited by enforcing phone companies to use low-frequency phones. For example, in Switzerland phones emit only 4µT, com-pared to UK phones which emit sometimes over 5,000µT! Many countries have buffer zones around mobile phone masts. With clusters of leukaemia occurring around electricity pylons,' " there' s little doubt that being close to devices emitting EMF is a health hazard.

But while there is a clear pattern of risk emerging, much research is being suppressed and much research is still to be done, so at this point it' s hard to quantify the risk. My advice is not to use mobile phones, and if you do, use them as little as possible and don' t keep them on your body. Keep them in a bag so your expo-sure is less. Also, don' t use hands-free phones at home, especially next to the bed, because the base station is permanently transmitting.
