Do you need to protect yourself from WiFi radiation?

I guess the first question that needs to be answered is ‘what is WiFi radiation?’ Which leads to the question ‘is WiFi safe?’

Because if you’re not clear about these questions it’s pointless talking about WiFi radiation protection.

What Is WiFi Radiation?

WiFi devices emit radio-frequency radiation, otherwise known as microwave radiation.

This microwave radiation is exactly the same kind of radiation that microwave ovens use to cook food.

Basically a microwave oven bombards your food with microwave radiation. This creates molecular friction which heats up the food. It’s known as ‘the heating effect’ or ‘the thermal effect’.

WiFi devices like wireless modem routers and wireless computers contain transmitters that use this microwave radiation to send information back and forth in the air.

The whole controversy surrounding the safety of these exposures revolves around this heating effect. On the one side there is the telecom’s industry and other vested interests saying because there is no observable thermal effect with WiFi and similar devices these technologies are safe.

On the other side there are now thousands of peer reviewed studies conducted by scientists from around the world that show WiFi radiation to be harmful. Not to mention extensive anecdotal evidence – this website alone is littered with testimonies of people that have experienced severe adverse health symptoms from these exposures.

Not surprisingly the World Health Organization has classified WiFi radiation type exposures as a ‘possible Class 2B carcinogen’.

WiFi Radiation Protection Tips

There are some simple steps you can take to limit your exposure to WiFi router radiation. In this article I explain what they are.

1. Buy The Right Modem Router

I recommend the TP-LINK Wireless N300. You’re probably surprised to hear me recommending you buy a wireless router.

The TP-LINK Wireless N300 is a wireless router with a difference.Wifi radiation - low EMF modem The difference being that you can switch the WiFi function off and it stays off. The customer reviews on this router on Amazon are outstanding – currently 4.4 out of a maximum of 5 stars.

Wireless routers are what most people buy, unfortunately, so this is where the best value for money is currently found in modem routers. You could buy a non-wireless version but these tend to be over-priced for what you get. The ideal set-up is the TP-LINK Wireless N300 and some good quality shielded Ethernet cable.

If your Internet is supplied by your cable company you need to buy a (wired) cable modem router.

2. Use The Right Ethernet Cable

low emf internet cableYour Ethernet cable is the cable that links your modem/router to your PC. It provides you with a hardwired internet connection.

Most people don’t give this cable a second thought. They use the cable which comes with the modem/router. Mistake.

This cable can be a source of RF radiation and so needs to be shielded. There are lots of different qualities of cable category 5, 6, 7 etc. I recommend buying at least Cat 6a SSTP (screened shielded twisted pair) Ethernet cable. Maybe the cable that came with your modem/router is Cat 6a SSTP. In that case you’re OK. If in doubt change it.

3. Learn To Switch Off

Look for software options to disable the Wi-Fi wireless module on devices like laptops, iPod Touches, iPADs, tablets, printers, projectors and anything else that might have Wi-Fi capability. Lower Wi-Fi power intensity is now an option on certain wireless set-ups. Look carefully what the software allows you to do. And keep your eye on it once you’ve changed the settings to make sure the default settings don’t come back on again.

If you’re unable to disable Wifi via the software you may be able to have the WiFi module physically removed (requires some electrical knowledge).

4. Swap Wireless For Wired

Replace your wireless keyboard,mouse, printer and whatever else you have that is wireless with USB wired versions.

5. Neighbors WiFi

Legally there is nothing you can do to oblige your neighbors to remove their WiFi so you need to have a softly softly approach. Go and see them, have a friendly chat. Ideally take an RF meter with you, show them the radiation levels they are exposing both you and themselves to. Take some print outs of some of the studies that have been done on the dangers of radio frequency radiation.

If they are unsympathetic EMF shielding should be considered only as a last resort measure. An effective WiFi radiation shield may well involve shielding several rooms – this is no small undertaking. Click here for more information on RF shielding.

Reduce Your Exposure To WiFi Radiation Without Eliminating It

I know that some people can’t quite bring themselves to surrender their wireless devices so here are some tips on minimizing WiFi without eliminating WiFi.

1. Keep your distance

WiFi radiation drops off significantly with distance (called the inverse square law). Many routers have a strong enough signal to maintain a connection up to 100m from the router. Make sure you put as much distance between you and your wireless router as you can without diminishing the efficiency of your connection. Remember: walls don’t stop wireless radiation, never situate a wireless router behind a bedroom wall.

2. Switch off at Night

Studies tell us that the biggest danger with WiFi radiation comes from nighttime exposures; cellular regeneration,Wifi radiation - timer rejuvenation, and detoxification is impeded. Notably melatonin production can be significantly reduced. If you really can’t bring yourself to remove your wireless router you can install a simple mechanical electrical timer (see attached image) on the socket where you plug your router in. Then just set it to turn the power off during sleep time.

3. Use USB Adaptors Wisely

If you use a USB Wi-Fi adapter (for PCs that don’t have a built in wireless network interface card) use it on a USB extension cable (10 feet or more). The same goes if you use a 3G or 4G USB internet stick, or dongle, to connect to the Internet while you’re traveling. A USB extension cable will significantly reduce your exposure. Tip: the further the USB internet stick is from you when you’re surfing the Web, the less you will be exposed.  Buy a USB extension that’s a good 10 to 15 feet long.

Is Powerline Networking The Solution?

This goes under various names ‘powerline networking’ or ‘broadband over power lines’ (BPL). Whichever name is used the principle is the same,  special adapters are used to send the Internet signal through your home or office wiring. What does this mean? It means you don’t need to have WiFi BUT these adapters do introduce radio frequency signals (RF radiation) on to your house wiring.

Combining RF radiation with power line frequency electrics is known to give rise to the phenomenon of ‘dirty electricity’. There are many health issues associated with dirty electricity. For this reason I do not recommend BPL as a safe alternative to WiFi.

The dangers of WiFi are real. Use the above tips to eliminate or reduce your exposure to WiFi radiation.

    Lloyd, please can you tell me if this N150 Netgear modem has an actual on/off button, or if you need to log on to the unit’s web interface?
    Thank you.

  • Lloyd said,

    Hi Colleen
    My Netgear N150 has a button on the front to switch the WiFi on and off and a button on the back for the power.

  • Colleen said,

    Thanks! 🙂

  • Omana Mammen said,

    Based on your document, I made measurements with wifi on and off. I removed wifi and cordless phone with aired connections. Thank you.

  • Michael said,

    Exactly, good article.
    For those thinking that wireless keyboards and mice are OK, these things can put out quite a significant signal and some at frequencies of 2.4 GHz. I have personally experienced terrible symptoms from one of these. The 27MHz analog transmitters are more benign but probably still significant for the electrosensitive, and can probably still harm anyone.

    Lloyd, I have TP-Link TD-W895OND,one of the cheapest modem routers. Does unscrewing the arial on router disable the ELF emissions? I only use this for Kindle conection to access Amazon.com. Thanks.

  • Lloyd said,

    Hi David
    Unscrewing the antenna on your router is not a good idea….it could focus the EMFs more locally (ie reduce transmission range) and thereby increase your exposure.

    There is a smart meter behind our bedroom wall installed by local municipal authority. My head at night aches – my wrists, ankles, knees and finger are sometimes very sore.
    Can this be a result of the smart meter?

  • Lloyd said,

    It could be due to the smart meter, EMF exposures affect different people in different ways see http://electricsense.com/1054/thirteen-good-reasons-to-switch-off-your-cell-phone/. Try sleeping in the room which is furthest away from the smart meter.

    Hi Lloyd,
    Fluorescent lighting & desktop PCs cause Electro-sensitivity with regards to myself. Consequently, I use a laptop through my TV to create distance and a wireless keybard & mouse and I feel 100% better! Therefore is there any need for myself to used wired key board & mouse?
