Swedish Radiation Protection Authority (SSI) Fourth annual report from SSI's Independent Expert Group on Electromagnetic Fields - March 2007

March 2007

This is the fourth annual report from the Swedish Radiation Protection Authority’s (SSI) Independent Expert Group (IEG) on Electromagnetic Fields and focuses on recent research on mobile phone telephony and health risks.

An update on the key issue of exposure from base stations states: "The few studies that have been published on health risks among populations living near transmitters have had major methodological shortcomings [IEGEMF 2003; IEGEMF 2005; IEGEMF 2006 (current report)]. However, the exposure to the general population that results from transmitters is very weak and one would not expect such exposure to produce a health risk as discussed in the previous report [IEGEMF 2003]. Indeed, one would assume that if RF exposure at low levels is associated with a health risk it would be considerably easier to detect it in studies of mobile phone users, or highly exposed occupational groups. The overall conclusion is that exposure from transmitters is unlikely to be a health risk." (p35/36)

61% of UK adults access the internet from mobiles

Mobile phones cannot work without a network of base stations (masts). There are approximately 52,500 base station sites (excluding microcells) in the UK. Only a third of these are large, free standing masts. A YouGov survey for MOA (Sept 2014) showed that nearly 8 out of 10 people recognise the link between masts and good mobile coverage. Mobile telecommunications are vital for the UK’s economic competitiveness and in promoting social inclusion. There are now 89.9 million mobile subscriptions in the UK. In Q1 2015 61 per cent of UK adults used their mobile phones for internet access. Tablet ownership is 54% of UK households.

No Established Health Effects

Mobile phones operate by using radio waves, similar to those that have been widely used for decades, for example in radio, TV and radar signals. A large number of studies over the last two decades have found no clear evidence of adverse health effects from the use of mobile phones or from phone masts.
