With a background in radon and radiation safety, we are capable of evaluating and reporting on radon gas levels, how they compare with EPA standards and whether a mitigation solution is called for.

EMF Testing for Electrical Wiring Issues Indicated by Excessive EMF Fields

Whether you believe in the safety hazards of EMF or not, the most common source of high EMF fields inside the home is improper wiring which fails to conform to current NEC code. ScanTech can detect and direct repairs on electrical wiring that manifests as an abnormal magnetic field.

We are often called out to site before a structure or complex is erected in order to survey and communicate any possible issues and the potential impact of nearby power lines, substations, transformers, cell towers and other EMF/RF generating sources. We also make construction recommendations for minimizing electromagnetic field emissions for safety and electromagnetic Interference concerns with sensitive manufacturing and research equipment.

Indoor air quality testing for VOC levels regarding Certificate of Occupancy permits according to City of Dallas Green Ordinances. Also known as the 804.2 Post-Construction, Pre-Occupancy Baseline IAQ Testing which is a 4 hour test for 500 uG / m^3 or less of VOCs.

Typical EMF & RF Sources in the Home

Homes have several potential sources for high EMF and RF sources including:

  •  External high voltage power lines (both primary and secondary feeders) which can produce elevated levels – particularly in densely populated urban areas / cities such as Dallas, Fort Worth, Houston, Austin, etc. or in homes near utility easements
  •  The main 120/240 volt feed entering the home through the power drop
  •  Breaker boxes
  •  Fluorescent lights (some also have an RF component as well which can cause equipment interference)
  •  High output halogen lamp banks such as those used in track lighting (uses a lot of current)
  •  Appliances with motors or heating elements (washers, dryers, refrigerators, etc.)
  •  AC Adapters
  •  Wiring Errors
  •  Outside Air Conditioning Compressors and Pool Equipment
  •  Wireless Routers, Cell Phones, Bluetooth and Cordless Phones (radio frequency only)
  •  Smart Meters (but fairly low level)
  •  Dimmers (though the range tends to be very short, but I have seen them wreak havoc with sensitive electronic equipment)

The focus should primarily be in areas exposed to EMFs where occupants spend 90 % of their time or greater – this sample schematic gives examples.

Smart Meters: Home Safety with regard to Actual RF Testing

Smart Meter, RF, Safety

Model GE I-210 Smart Meter

The controversy of Smart Meters is getting so prevalent that I feel a compulsion to share some of my data with respect to certain claims and fears that the public has about this deployed technology. There are a number of website and organizations dedicated to banning this device for various reasons. Some of them deal with potential privacy invasion issues or the theory that the power company can somehow selectively turn off certain appliances without your permission.

While I cannot comment on the political or civil liberties aspects of the Smart Meter debate, I have now done enough measurements to get an idea of just how much energy these devices are putting out and probable public exposure.

The short answer is: not that much.

Now before you think that I am on the side of the utility or power companies, I actually have some criticism of at least one power company’s portrayal of how low the levels from Smart Meters are:

Smart Meter RF Safety Homes

Smart Meter RF Comparison Chart (BTW, I do NOT entirely agree with this)

For one, I cannot believe that a Smart Meter puts out less RF than what emanates from a human body (I have no idea where they are getting that notion from – even brainwaves are severely attenuated outside of the body which is why electrodes are needed for EEGs) or the earth itself – at least not at point blank range.

And this brings up another hidden factor – at what distance from the source are these measurements taken? Because radiated power from an ideal isotropic antenna falls of with the square of the distance, if you even move the measurement meter a few feet from an RF source, the power levels drop dramatically.

Also, they are using milliWatts per cm^squared instead of the more typical microWatts/cm^2 (or uW/cm^2) which is more routine for measuring low level RF at a moderate distance. I suspect the reason why is because in using the milliWatts convention (in which 1 milliWatt or mW is = 1000 microWatts) you get to put all of those zeros after the decimal place and make the numbers seem even smaller.

There are specific reasons why I have chosen to point these specific concerns out besides just being picky – they also inform the reader to pay attention to the context in which this data is presented.

I just got done measuring my Smart Meter and at a distance of 3 feet which is as close as anyone would even causally walk past it, I only get a maximum of 1.5 uW/cm^2. That only occurs in a very short burst (less than one second) every minute or so, so the actual exposure averaged over time would be far less. (closer to the nanoWatt range) Please note that such an intermittent burst is NOT the same as the pulsed signals that you read about as being harmful. Those are frequencies are continuously pulsed in at least the MHz or GHz range – what I am talking about is more like a substantial fraction of Hertz or 0.016 Hz if it is one second out of every 60.

My cell phone when running at full power puts out over 2 uW/cm^2 and it is right next to my head when making a call. While the frequencies involved are somewhat different, the RF dosage is roughly comparable except that the cell phone is consistently much closer to my body for more extended periods of time. I doubt I spend more than 30 minutes a week being within 10 feet of my Smart Meter.

What non-technical critics also fail to realize is that the metal backing of the case on the Smart Meter which is in between the RF and the occupants inside the home is grounded and right next to the point source – therefore shielding much of what is already fairly low level RF.

Also what many people seem to forget is that the Smart Meter mounting locations are at the main power feed or drop into the home where the magnetic field tends to be the strongest. Therefore as a very respected EMF consultant pointed out recently, it is not the RF from the Smart Meter that should be such a concern, but the elevated magnetic fields that you get in the vicinity of any major power feed into the home.

But the bottom line is that if someone is convinced that a Smart Meter installation at their home is a threat to their health or the well-being of their family, then there is no sense in arguing the point.


My primary role is not to change someone’s mind, but to help them find peace of mind with a set of feasible solutions. Have you ever had something that seemed small, like a cupboard door that doesn’t hang quite right, or an argument with a coworker that just stuck with you all the rest of the day? We are unsettled because of the feelings of things not being symmetrical or completely in our control and regardless of the actual relevance or meaning, it causes stress and stress is definitely a factor in disease, accidents and our enjoyment of life.

So for legal Smart Meter mitigation, what I CAN recommend is a particular form of shielding that is currently approved by the local utility here in Dallas, Texas (ONCOR) that can be placed over your meter. By my measurements it reduces the RF by at least 95 % and I know someone who has at this writing has ONCOR’s express permission to install them. (installing one yourself can get you into trouble with the utility company if you remove the locktag to access the backside of the meter)

Please contact me at www.scantech7.com for details if you are interested.

BTW, trying to make one yourself such as a solid Faraday cage will probably block the data signal and also get you into trouble with the electrical company. The price of one installed by this particular gentlemen compares very favorably with other units sold on the Internet. Furthermore, it is rugged and designed to be vandal resistant so even if RF protection is not of interest, it may be a good investment for commercial customers looking to reduce the costs of malicious destruction.
