A recent Swiss study shows that the general public's RF exposure comes more from masts than from mobile phones, with DECT phones running a close third.
Frei et al (May 2009) produced a study looking at RF exposure experienced by the general population. About one third (32.0%) came from mobile phone masts, mobile phones were responsible for 29.1%, and DECT phones 22.7%.
This means that studies (such as the 13-country Interphone study investigating RF exposure and potential health effects resulting from such exposure) as a result of using mobile phones alone, without allowing for masts and cordless phone usage is flawed, and does not reflect reality. Masts and DECT phones account for more than 70% of people's of people's exposure to RF.
