Governments and the mobile phone industry are researching the effects, including:
● the effects of radio waves on blood pressure and the brain, such as the abilities to concentrate, remember and learn the connections between mobile phone use and brain cancer long - term effects of mobile phone use, looking at health histories of people who have used mobiles since the 1980s. They will be looking at both current mobile phones and the new generation of 4G phones. The results from these studies will help us understand more about the world beyond mobile communications.
