We can find many EMF / EMR sources in the outdoors. If it is in the city or in the big outdoors. The sources are usually part of infrastructure.

Outside the house
While you are outside the house, on a trip, on your way to work, or if your house or working place is close by to an EMF/EMR(Electromagnetic Fields/Electromagnetic Radiation) source, you may be exposed to outdoor EMF/EMR sources in high and low frequencies.
- Low-frequency sources:
- High and low voltage Electric power lines.
- Electric substations.
- Street power converters.
- Electric transportation power lines.
- High-frequency sources:
- Wireless communication facilities.
- Cell phone masts.
- TV and radio broadcasting stations.
- WiFi and WiMax regional communication equipment.
- “Smart City” components
- Military communications, Radar and Electronic warfare equipment.
How to limit exposure?
You have some control over the EMR sources in your home and workplace by keeping a safe distance, minimizing the use and unplugging the source of EMR when not in use. When you are outside you have almost no active control over the EMR sources. What you have control over, is yourself, and yourself only. Using some products that are available on the market, you can control your exposure and reduce it to the minimum possible.
- Keep a safe distance from antennas (more than 100 meters for a non-EHS person, several hundred meters for EHS person).
- Use shielding products to reduce the penetration of the EMR to your house via the windows and opening.
- In extreme conditions (like in case that your house is next to a mobile phone mast) you can paint your external walls with RF electromagnetic blocking paint.
- For EHS – Wear an “EMR protective hat” (make it yourself or buy it over the net).
- For EHS – Wear clothes made out of EMR blocking cloth.
EMF / EMR sources outside the house
- Cell towers aside the roads
- Cell tower on buildings
- Power lines
- Power conversion/transmission centers emitting ELF radiation along the roads
- Army/Security/Air fields/Sea ports radars and infrastructure
