The Health Protection Agency (formerly National Radiological Protection Board) issues different reports and information booklets on different aspects of (amongst others) mobile phone effects. According to their 2010 statement "there are thousands of published scientific papers covering research about the effects of various types of radio waves on cells, tissues, animals and people. The scientific consensus is that, apart from the increased risk of a road accident due to mobile phone use when driving, there is no clear evidence of adverse health effects from the use of mobile phones or from phone masts".
