Health Considerations – Electromagnetic Radiation: Radio Frequencies are Everywhere

If you are concerned about the massive proliferation of wireless radio antennas – cellular 3g, 4G, and the upcoming 5G; WiFi, Bluetooth, and smart meters – there have been few independent studies of their effects on humans, animals, and even the bees. We do know that children are more vulnerable to electromagnetic radiation than adults are – with their thinner skulls and less-developed immune systems – safety should start with them.

The telecom industry is not interested in exploring this themselves for obvious reasons – they don’t want to find out the bad news is for certain, nor do they want additional attention from government regulators! Thus far, for the most part, they have been given free rein. There are some independent studies on the effects of these radio signals (which are in the microwave frequency range) that are finally emerging – indicating definite risks – but it’s still too early to fully understand the extent of the impacts of RF on living cells.

Your best bet is to take precautions now to minimize your RF exposure while we participate in this latest “experiment on humans”. A case in point: it took decades for the truth to emerge from the tobacco industry, and many medical doctors were regular smokers at one time!

Some people have complained of heightened sensitivity to the “everywhere RF”, while others seem to not notice at all. There have been RF neutralizer stickers on the market for over a decade which may be helpful – their effectiveness is also difficult to quantify, as there are many variables to consider when measuring exposure – the device’s manufacturer, position of antenna, and activity mode, and these wear out after 2-3 years.

More recently, RF-blocking devices have arrived in the marketplace the form of phone and tablet cases and are certified effective. I recommend the SafeSleeve wireless device cases.

Read below for effective best practices to minimize your exposure now, with or without an RF-blocking or neutralizing device.

How to Minimize your RF Exposure

Cell Phone Electromagnetic Radiation

Without exception, the farther you are away from any type of radio transmitter, the better – the signal strength effect on human tissue plummets with distance. The intensity drops with the square of the distance – which you can use to your advantage. Holding your phone 5 cm (2″) from your head on a call will expose your head to 100 times less thermal radiation than if the phone is 0.5 cm (0.2″) from your head. Just a few inches away from your body makes a huge difference. Using the speakerphone function and placing the phone on a desk or table affords you about 2 to 3 feet distance from your head – vastly reducing the effects.

If you choose to wear earphones, the best ones are the air tube type that pass the audio signal though the air at the earpiece, removing the electrical connection from you. I recommend Dr. Mercola’s “Blue Tube” (equipped with 3.5mm jack).

Regular hardwired earphones can act like an antenna amplifying the RF entering your ear. But if you’re listening to music in airplane mode and your music is already contained in your phone and not being streamed from the internet (like an iPod) – there’s no RF to be concerned about under these conditions and any hardwired earphones will do.

Cellular Bars: Do not use your cellular network when the signal strength is 1 to 2 bars. Move to a better coverage area of 3 to 4 bars. Low signal strength coverage will trigger your cellular device to transmit up to 10,000 times the RF signal to compensate, to reach the nearest cellular base transceiver station and maintain a reliable connection.

In Your Vehicle: When in your car, mount the phone on your dash by the windshield (not below) which will be in line with the glass of the side and rear windows) to cut down on your phone transmitting RF signal off all the metal surrounding you in the car – ricocheting and magnifying the RF in that confined space. (There may be laws in your state prohibiting mounting your phone in certain locations in your car – it being a projectile risk during a collision – please check your state laws for details.)

Walking: When carrying your phone, keeping it in a purse or computer bag gives you that precious few inches gap away from your body. Alternatively, you can put it in airplane mode (turning off the radios completely), as long as you’re OK with missing incoming calls, texts, and data. I often have my phone in my pocket this way, but can’t do that if I’m expecting an important incoming call or text. In those instances, I carry the phone in my hand slightly away from my hip, as I walk along, away from a car or building.

WiFi – Where to Place your Wireless Router

Install your wireless router as far away as possible from your main living area where you spend the most time, and away from your bedrooms, and turn it off overnight since it will not be in use. I used to keep mine in the garage (with year-round moderate temperatures) when I lived in a single family home, and found a good location there that still allowed for a good signal throughout the whole house. Be aware of locations in your home where you have large amounts of metal – metal cabinets, appliances and mirrors can block the signal from where you are sitting – it’s line-of-sight. Keep that in mind when placing the router.


This signal can vary 10-400 times in RF signal strength among device manufacturers, which confuses things somewhat. The positive is that even in the worst case, Bluetooth is a weaker signal than cellular or WiFi. Bluetooth earphones are at least 10 times weaker than using a cellphone right up against your ear, but keep in mind, RF exposure is cumulative – it all adds up. Turn off BlueTooth radios when not in use.

Smart Meter

If your electrical utility has already installed a smart meter at your residence, place a metal shield or foil on the wall inside your home, directly opposite where the meter was installed on the outside wall (or if the positioning is workable – a mirror, or a picture or painting with foil hidden on the back of the frame). Opt out of a new smart meter installation if you can. If you’re in a multi-unit complex, note where the meters are installed – hopefully, not right on your unit’s exterior wall. If it is, use the metal shield on the inside.
