Last Friday i went to give a lecture about electromagnetic radiation in a building where a cellphone antenna was contracted next to it on a neighbored building. The people that came to the lecture were very upset with the cellphone antenna, but they all had smart phones. In the living room of the apartment the lecture and meeting was done in there was a wireless routed, a DECT phone and 3 kids, one with a 10" tablet, the second with a iPhone and the third with a Samsung Galaxy smartphone, all surfing WIFI and playing internet games.
The RF levels inside the living room were very high, about 5mW/m2. after the WIFI router and the DECT phone were turned off (the kids stopped playing for a minuet) the levels drops to 0.2mW/m2 just next to the windows.
People are not aware that all these smartphone, tablets and other wireless devices emit RF radiation. all the worry abouth is the cellphone antenna.
