Q&A: Wi-fi health concerns

A number of education professionals have raised concerns about the use of wi-fi internet networks in schools, following a Panorama report into the technology. So just how safe is it?

All this article did was raise an open-ended argument about the safety concerns about using Wi-fi. No conclusions, no evidence either way, only speculation and an elevated concern were brought to the subject.

Actually, I was reading a scholarly article the other day, that GSM networks emit fields that can disrupt the blood brain barrier and cause nuerological problems such as destruction of nuerons and adhesion of various plasma proteins to the brain (which is bad). This was carried out on rats, and there was siginificant evidence that these signals could impact humans as well, although not as significantly. Wi-fi networks indeed could have a similar effect, just because we haven't heard anything about it yet that would give grounds for decreased use of wi-fi networks, doesn't mean we should be ignorant and assume that it's perfectly safe. Remember how long smoking was prevalent untill some doctors decided to speak up, the next big thing will be soft drinks, but large companies are doing their best to shut up all the doctors.

Your post is more interesting than the article. I would like to read this paper you speak of if you still know where it is...

You deserve a bubble for your "research" and your mature, informative post.

Search: GSM rats blood brain, in google, it's the first article that comes up in PDF format. It's a scholarly article so you may need special permissions to view it.

EM radiation has always been the source of discusion for health. Every since radio, people have wondered the impact on the body. MOst research now agrees that the exposure rate is exteremly low, especially considering regualr backrground radiation from natural elements such a radon and xenon. In fact, unless you have many x-rays in a year, natural radiation dwarfs your total exposure. Wifi is simply a specific EM frequency in a soup of the Em spectra floating around in the air. Until you go into X-ray energies, there is no acute effect and very little long term of such low exposure.

The funniest thing about this article is that it is the "education professionals," and not any sort of field and wave expert, that think it is dangerous. People always complain of cell phones and power lines giving them cancer. The loudest complainers are usually the most ignorant of the subject.

The best part is the scientific study citation.

"Some scientists have reported that low levels of non-ionising radiation can cause damage to chromosomes. But there is currently no scientific evidence that wi-fi, in particular, causes this to happen."

In other words we can't prove anything, but we know it must be there. Who are these scientist. Are they professionals with advanced degrees or are they a group of eighth graders in a science class.

You have to love consensual science.

Also if you think about, light is an EM wave (breaks up into frequencies and hence different colours), and light waves (let's ignore all this photon/energy stuff to make things simple) behave much in the same way as radio/microwaves, while they have a shorter wavelength...shorter wavelength equals higher frequnecy waves, so realistically, if wi-fi networks, which run in the lower end of the EM spectrum can be damaging, then so can light waves, but we know that's not really true (only UV radiation is where things start to become harmful). So this clearly has to do with the quantity of signals transmitted, and possible how the waves are encripted. I'm sure we'll find out eventually haha. Also, wi-fi networks use waves that are microwaves, yes, the same waves in microwave ovens, so that's another thing to think about. most people are ignorant and don't know that microwave ovens don't cause particulairly harmful radiation, it's just at the frequency of microwave ovens the waves can easily penetrate and heave fats/oil/and watery substances, and that's the premise of its functionality. In closing, don't be ignorant regarding such issues, there is enough evidence around to suggest that damage is being caused over time. I guess, instead of killing time on N4G do some research folks, opinions don't count when you don't have facts to back them up.

I see where you would like to go with your argument but your logic is not correct. Your statement that longer wavelength EM radiation is harmless because light has a shorter wavelength and it does not "harm" us is untrue. Excitation of atomic states, molecular states, and chemical bonds are not that simple.

For instance, hydrogen's ionization energy is around 13.6 eV, which has an associated wavelength of about 91 nanometers (or 91*10^-9 meters). But hydrogen also absorbs a much longer wavelength at 21 centimeters (or 21*10^-2 meters).

So in short, unfortunately your argument doesn't work.
