If we are going to get on the cell phone issue, my understanind from an FCC colleague is that the issues relate to older cell phones, which they do not know how many people might use. Older analogue devices which used to produce 1.5 to sometimes 3 WATTS, (yes we used to hold those bricks to our heads) clearly are transmitting high power, ping for a tower and sending EMF which could get anywhere,
Now, how many people are really using such a device today, don't know. They don't really know either.
It reminds me of the complete abstinance from alcohol during pregnancy, which we KNOW isn't really the case, but it will catch all the people who would be a risk group.
