All those signal relay sites

So, so many of these relay devices on rooftops here..

I believe the jury is still out on how dangerous it is to live or work very close one...
 let me see if I can google something.... 

Internet article from the American Cancer Society says there is very little risk of getting cancer from living below one of these things...also, as the electronics involved :


"When a cellular antenna is mounted on a roof, it is possible that a person on the roof could be exposed to RF levels greater than those typically encountered on the ground. But even then, exposure levels approaching or exceeding the FCC safety guidelines are only likely to be found very close to and directly in front of the antennas. If this is the case, access to these areas should be limited.
The level of RF energy inside buildings where a base station is mounted is typically much lower than the level outside, depending on the construction materials of the building. Wood or cement block reduces the exposure level of RF radiation by a factor of about 10. The energy level behind an antenna is hundreds to thousands of times lower than in front. Therefore, if an antenna is mounted on the side of a building, the exposure level in the room directly behind the wall is typically well below the recommended exposure limits."

I still wouldn't want to live right below one of these things, I guess I am superstitious.
