199+ Ways to Lower Your EMF Exposure Today:


Common External EMF Sources


EMFs Originating from a Variety of Outside Sources

10 External EMF Sources

This section focuses on external EMF sources to be aware of.

Not every home will have each of these to take into consideration, but it’s good to be aware of what sources may be a hindrance in achieving a low EMF home environment.

Many of these are helpful in noting when in the process of looking for a home or apartment to purchase or to rent.

Unfortunately, some of these sources (cell towers) can be added to areas with ease and therefore the EMF landscape can change rapidly.


Cell Phone Towers

Cell phone towers are the backbone of the wireless communication industry. As you can imagine they give off a sizeable amount of radio frequency radiation.

If possible, we advise people not to live next to, work close to or frequent areas (children’s playgrounds, for example) that are adjacent to these.

This is especially true after the National Toxicology Program study.

5G Small Cells

5G cell towers are starting to be rolled out in urban areas. These cell towers are much smaller than the previous generation towers and can be placed on street lamps and telephone poles.

Be aware of these as they’re being rolled out in your local area or if you’re searching for housing.  This isn’t something you’d want adjacent to your apartment window.

A Low EMF Solution

As with all radio frequency radiation, the fields emanating from these can be blocked with RF shielding material. Learn about “How to Shield Against 5G.”


Power Plants

Power plants will have very elevated levels of magnetic fields from the generation and distribution of the electricity they produce.

These are hard to miss when looking for a new place to live, but try and find a home or apartment away from power plants and the large transmission lines originating from them.

A Low EMF Solution

The advice here is one of our most common pieces of wisdom: Distance yourself from the source.


Electrical Substations

These are less noticeable than the power plants, but can still produce surprisingly high levels of magnetic fields.

We always advise keeping a distance from these when selecting housing, playgrounds or other areas you’ll be spending time in frequently.


A Low EMF Solution

As with power plants and transmission lines, keep your distance from these, if possible.


High Powered Transmission Lines

This category includes the massive metal structures constructed for the transmission of electricity over larger areas.

It’s always worth testing, but these will almost always have extremely elevated magnetic fields and are very difficult to shield.

If possible, we recommend that you don’t live, work or regularly play near these behemoths.

A Low EMF Solution

These can be measured with a guassmeter. Visit our Best EMF Meters page to learn more.

Overhead & Underground Electrical Distribution Lines

Distribution lines are the smaller overhead and underground lines in your neighborhood that bring electricity into your home.

These can be all over the place in regard to the magnetic field intensity, so you’ll want to have these surveyed. An EMF specialist can help you with this or you can DIY with a gaussmeter.

Digital Broadcast Towers and Dishes

These towers broadcast digital AM/FM/TV signals. The older analog radio signals weren’t as worrisome, but the newer pulsed, digital signals are similar Rf radiation to cell phones and wi-fi.

If possible, these are worth avoiding in domestic and professional settings.

A Low EMF Solution

The RF radiation from these can be shielded against, but the easiest solution is distance.


Airport Radar

Civil and military radar installations can produce high levels of microwave RF radiation. We recommend people avoid these if possible.

Like all forms of RF radiation, radar can be shielded against with varying degrees of success.

Here’s an article on radar published by the World Health Organization.

Current on Plumbing & Other Utility Lines

Electrical current, instead of completely returning to the power company in the same manner it entered a home, will sometimes exit a home through utility lines.

Commonly, this occurs through metal water pipes to the utility pipes in the streets.

From there, it can actually go from the utility pipes in the street up your metal water pipes and into your home and then cause elevated magnetic fields.

It sounds bizarre, but it’s not uncommon.

It also happens on other utility lines, like cable television and telephone lines.

The expertise of an EMF consultant comes in handy in these situations, but you can purchase a clamp meter and test for excess current on you utility lines yourself.

We’ll publish our page on How to Prevent Magnetic Fields from Excess Current soon.

Visit our page on The Best EMF Meters of 2020 to learn more about clamp meters.

A Low EMF Solution

Decent clamp meters are affordable and are invaluable in determining if you have current coming in from your neighbors or wiring errors of your own.


Your Neighbors

Your neighbors, both residential and commercial (if you live in an urban area), can be responsible for EMFs in your home in a number of ways.

Some examples include:

– Placing their wireless router near a shared wall.
– Placing a cell phone booster right next to your home.
– As mentioned in the previous section, if they have a wiring error in their home, this can cause electrical current to travel up utility lines and into your home, causing elevated magnetic fields.

A Low EMF Solution

If you’re on good terms with your neighbors and explain your concerns to them, many times they’ll be happy to move their tech products farther away. You may even be persuasive enough to get them to stop using the tech altogether.

If that doesn’t work, you can always contact an EMF professional to see what your shielding options are.
