Is WiFi radiation safe?
Judging by the many devices that now use WiFi it’d be difficult to believe that it’s not safe.
10 years ago WiFi was virtually unheard of.
Now WiFi is everywhere.
It’s in the home, in the workplace and even in the street.
It’s in Internet connections, in video game consoles like the Nintendo Wii, the Playstation 3, the Xbox360, in PDAs, in mobile phones, and in a whole host of other types of consumer electronics.
So WiFi must be safe, right?
WiFi devices emit radio-frequency or microwave radiation.
Wireless modem routers and wireless computers contain transmitters that use this radio-frequency radiation to send information back and forth in the air.
This radio-frequency (RF) radiation can penetrate walls made of wood, concrete and metal. It can easily penetrate our bodies.
There are now thousands of peer reviewed studies conducted by scientists from around the world that show WiFi radiation to be harmful.
These scientists and medical experts are speaking out, here’s what some of them are saying:
Professor Olle Johannson Dept. of Neuroscience Karolinska Institute Sweden
Dr. Magda Havas Toxicologist at Trent University
In this article I explain what WiFi is, I explain the dangers and I explain what you can do to protect yourself.
What Is WiFi ?
WiFi is a registered trademark owned by the WiFi Alliance. The WiFi Alliance defines WiFi as any wireless local area network (WLAN). By definition WiFi does not use any wires it uses radio frequency technology.
Webopedia defines radio-frequency as any frequency within the electromagnetic spectrum associated with radio wave propagation and gives the following analysis of the frequencies that make up the electromagnetic radiation spectrum :
- Ultra-low frequency (ULF) — 0-3 Hz
- Extremely low frequency (ELF) — 3 Hz – 3 kHz
- Very low frequency (VLF) — 3kHz – 30 kHz
- Low frequency (LF) — 30 kHz – 300 kHz
- Medium frequency (MF) — 300 kHz – 3 MHz
- High frequency (HF) — 3MHz – 30 MHz
- Very high frequency (VHF) — 30 MHz – 300 MHz
- Ultra-high frequency (UHF)– 300MHz – 3 GHz
- Super high frequency (SHF) — 3GHz – 30 GHz
- Extremely high frequency (EHF) — 30GHz – 300 GHz
Power lines operate at 50 to 60 Hz are located in the extremely low frequency range, ELF. An FM radio for instance operates in the VHF range, usually between 88 and 110 MHz. Analog TV operates in the 400 – 600MHz range, Digital TV is in the 600 – 1000MHz range. Cell phones operate in the range of 850 to 1900 MHz (0.8-1.9GHz), UHF, depending where you live in the world.
WiFi has a carrier signal in the 2.4 GHz range (which is nearly S HF) with some more recent devices operating in the 5-6 GHz range AND a digital pulsed signal of 10-250Hz which penetrates walls, ceilings, floors and not to mention humans.
WiFi radiation is commonly termed RF (radio frequency) radiation because it operates within the range 3kHz-300GHz. It is also called microwave radiation. Microwave radiation is in fact a subset of RF radiation, it operates in the range 300 MHz to 300 GHz.
Is WiFi More Dangerous Than Cell Phones?
So cell phones and digital TV are operating broadly in the same frequency. The reason why we don’t hear any alarming reports about cancer and digital TV usage is probably because your digital TV is not positioned a few centimeters from your head.
But WiFi is operating much higher up the spectrum than these other devices, more energy is in play. Fortunately WiFi modems and transmitters are not held in such close proximity to the human body as cell phones, or are they? Certain cell phones also offer a WiFi functionality.
WiFi Pollution Is Non Stop
For me the biggest problem with WiFi is that these things throw out electromagnetic radiation 24/7. And its pulsed microwave radiation just like cell phones.
The majority of people these days have a cell phone but invariably this cell phone is not switched on all the time. If you have a WiFi router at home this generally operates 7 days a week, 365 days a year. Sometimes people are sitting in offices completely oblivious to the fact that they are exposing themselves to WiFi radiation.
How To Make WIFI Safe And Cut Down On Your Personal Electrosmog
The only way you can effectively reduce reduce your exposure to electrosmog is to measure your electromagnetic pollution using an emf meter. These have now become inexpensive easy to use devices which can easily detect and measure the radiofrequency pollution in your home or workplace.
You don’t have to take my word for it when I say that WiFi is very bad for your health. There are more and more studies which point to the adverse health effects of radio frequency radiation.
I have never had WiFi in my home. I make sure that the WiFi function is disarmed on my modem and also that it is disarmed on my laptop, and I test regularly with my EMF meter for WiFi radiation from my neighbors routers, I would advise you to do the same.
