Are 5 GHz telephones safe?

I read in sci.electronics.design that Bill Bailley wrote (in ) about 'Are 5 GHz telephones safe?', on Mon, 21 Feb 2005:

DEW is/was perfectly capable of cooking you alive at many metres from the antenna. Even a cellphone, let alone a cordless phone, won't do that.

If we hadn't all been living for the past sixty years in fields at similar frequencies from TV transmitters orders of magnitude more intense, with no sign of sickness clusters, I might be less sanguine.

Popcorn may be going a bit too far.

However, there is a growing body of knowledge that links the incidence of the rare near-brain tumour known as an "Acoustic Neuroma" with the increased use of mobile phones and cordless telephones.

This tumour is suspected to occur more frequently in those who have had exposure to microwave radiation at the sort of power levels used for line of sight communications. Exposure to radar and tropospheric scatter energy can also be linked with this tumour.

It should be said that this is a benign nerve bundle tumour and usually slow growing. It can eventually grow to a size that seriously restricts space for other nerve bundles, and can cause disability/death from this cause. Treatment will almost always involve head/neck surgery, and a strong possibility of post operative conditions such as deafness/poor balance/poor swallowing/facial droop/loss of eyeblink etc.

As always, there are as many opinions about the effects that radio energy can have on the human body as there are specialists who work in this or allied fields. It would seem prudent though, to reduce prolonged close exposure to all kinds of radio energy until studies on this subject are more nature.

Frequency and modulation no doubt have a lot of influence.

Err, you're so far off that it's ridiculous. Microwaves operate on 2.45 (or is it 54) GHz.

3*10^8m/s /2*10^14Hz = 1.5*10^-6m, or what's commonly called infra-red. (treble the frequency and you get green)

TV is heavily pulse modulated at (in the UK) 25Hz. This is very close to the frequencies that the doom lobby claim to be particularly bad at invoking the evil fairies, or whatever.

I suggest you check the work of Persinger and others concerning effects of low level mag fields and modulations.

I think the real problem is that nobody is quite sure at what power level cell damage occurs and over what span of time. Please take care and think twice before you extend that mobile call a second longer than is required.

For myself, I worked on the DEW line

and on military troposcatter in a number of different parts of the world.

Shor nuff, some years later, a golf ball size acoustic neuroma. A good surgeon and some luck, still here.

That pesky inverse square law can sure trip us all up if we are not careful!

"I think the real problem is that nobody is quite sure at what power level cell damage occurs and over what span of time."

The plain truth, is that no one is yet ready to write about cell-phone dangers, large, and in letters of fire. However, the warning flag is being gently waved, and it may be time to shade the odds to your advantage.

Regards, Bill.

Nope it was the water see:

I suggest you try and find any evidence that any mobile phone, anywhere has ever caused anybody actual harm by way of its RF field.

All you will find is urban myth.

And there was no warning label about that sort of thing on the CD-ROM drive, I'll bet.

It's caused me harm. By a bizarre coincidence of events, a mobile ringing on top of a CDROM drive with its cover off caused the drive to eject, and push a coffee cup over on my head.

I've always known that coffee is bad for you. This proves it.

Remains to be seen since cancer takes up to 30yrs to manifest. I'll let you know the definitive opinion around 2020

As I said, we have lived in similar, but vastly more intense radio fields for sixty years. You can voice a definitive opinion right now- there is no problem.

(ps, please don't come back with the weak fields argument; people who live further from TV transmitters enjoy exactly these weak fields, and still no effect) Pearce Consulting

I'm sorry _ I misread what you wrote here. Mobile phones don't generate mag fields. The earth, however, does and to modulate it all you need to do is turn round.

Not "vastly more intense" than holding a transmitter next to the brain on a regular basis for hours a week. Nor at the more absorbable high frequencies of mobile phones.

Dirk The Consensus:- The political party for the new millenium http://www.theconsensus.org

The implications of Persinger's work goes beyond low level mag fields, and mainly concerns modulations. I would not have believed effects were possible as detailed, except that it does seem incontravertible.

Persinger's work has been comprehensively discredited.
