I meant to say “RF” sorry…I recently purchased a Trifield TF2 EMF meter to check the RF radiation around our home. I’m concerned about my family and our house is on top of a large hill over the trees in direct line of sight of cell towers, and various TV and radio antennas. Most of these antennas are around 3-5 miles away but due to being on a hill I can see that far. There is one cell tower about 2,000 meters away but it is not in direct line-of-sight. Anyway, basically we were surprised when we turned it on the readings at our house were around 0.5-5.0 milliwatts per square meter. At the bottom of our driveway which is around 200 ft lower elevation and throughout the subdivision the readings are around .02-0.2 mW/m2. If I go drive to the large cell towers around town and the one closest to our house the readings directly under them are around the same as at my house… some higher some lower. This doesn’t make sense to me but I am not by any means an expert in EMF measurement. This has bothered us enough were we have thought of selling the house. I thought we were far enough away from the towers but is the line of sight that is the problem or am I picking up something else that isn’t a concern? Any ideas? Thanks!

Hi Derek, welcome to the forum. Obviously I can only offer suggestions and impressions from what you have said, but if the readings are definitely in MILLIwatts (and not MICROwatts) then they seem higher than I would expect from a tower 3 miles away. I would be looking for a more local source of radiation. In this situation a directional meter is very useful. They tend to be expensive, but you might be able to hire one, or hire a person who has one and knows how to use it (such as a Building Biologist). Sometimes masts are hidden in artificial trees or inside buildings.
Personally I would not assume that the source of a signal of that power is something ‘of no concern’, but it would obviously be helpful to know exactly what it is so you can make an informed decision about how concerned you should be. It might be something which could be screened (there is info about screening on the main site here).
I’m assuming you have removed or switched off all possible sources of radiation in the house when doing the measurements, such as cordless phones, wifi, baby monitors, mobile phones, smart TV’s etc. Do you have a wireless smart meter? They can produce high levels of radiation.

I confirmed on the manual and the RF measurements are in milliwatts per square meter (mW/m2). Our house is actually under construction being built so there is no power in the house. I guess I should have checked this out before building… oh well. Anyway, the power company said they don’t use smart meters at the temporary power meter which is over 150 ft from my house. I took some additional readings yesterday outside the house and they are even higher than inside the house. I have several outside around 7.0-15.0 mW/m2. From what I understand this seems extremely high. As I mentioned at the bottom of my driveway and all around the subdivision the readings are around .02-0.2 mW/m2. I also went on the back side of the hill down around 20 ft lower than where my house is and the readings are in the .05 range. There must be something to me being up high and all the towers being line-of-sight is all I can come up with even though they are mostly miles away. Also, I guess their strengths would be combined. I am just surprised that it is as bad as living within 50 ft of a large cell tower. I certainly don’t want to live next to that the rest of my life with my family and if being up high is the equivalent I guess I don’t want to live there either. Any other thoughts? Thanks for your response.

Very strange…. There’s little I can add to my previous post. You are right – the power from multiple towers is cumulative.
Just a couple of thoughts. Is there a local building biologist/expert who could tell you if this is normal for your area? To me it would suggest that the towers you are seeing must be transmitting at very high power.
A couple of web sites to check for information:
Geovital (see videos below)
Oram Miller – http://www.createhealthyhomes.com/
If you are in the process of building you may have an opportunity to build in some protection. Here are a couple of videos suggesting how you could approach it (ignoring the commercial content – though they might be useful people to contact at some point).
I know that the y-shield paint is effective, as a friend used it to block wifi etc from a neighbour. Whether it would be sufficiently effective in your situation is something you would need to discuss with a specialist.

I thought I would let you guys know I figured out where the RF is coming from. It is mainly from 4 2,000 ft tall broadcast TV towers putting out at least 4 million watts. I confirmed the effective power radiated on the FCC website. I had no idea the broadcast towers were so powerful. The power they put out dwarfs every other source from what I have researched. I’m seeing cell towers with 30,000 watts and FM radio towers with 50,000 or 100,000 watts but each tower putting out a 1,000,000 watts each is insane. Especially when you consider a grouping of 4 together.

Nice detective work! Of the scientists I follow the only one who consistently mentions broadcasting facilities seems to be Trevor Marshall. He puts them in the same category as cell towers etc, and points out that issues have been known with these since the start of TV and particularly FM broadcasting. Unfortunately he doesn’t seem to have a blog, and only does brief comments on Twitter. If you’re sufficiently interested it might be worth looking through his previous comments – @trevmar on Twitter. Not much recently, but here’s a sample:
‘NB: British Telecom is not just warning about cellphones and Cancer, but ALL “radio frequency emissions and health risks.” BT knows that AM,FM Radio (etc) can also damage health (not just phones cause Cancers). ‘
I suspect these frequencies are harder to block…….. especially at these power levels.
