Wi Fi and Health

[allgowireless]

Hi All

My better half is a little worried will all the 'rays' flying about the house and is concerned that i am 'frying her bits'. Is there any information regarding the health effects of wi fi or any studies into SAR.

I would appreciate any help you guys may have as the only alternative is to bow to the 'technophiles' paranio....

Cheers

I worked on a project to integrate wireless LANs (2.4GHz) into patient monitoring devices for hospitals. We had a medical expert on the team, and we found no health issues in the 2.4GHz band.

WiFi gear operates at such low power outputs (30-100 mW typically), that unless you insert the antenna into a bodily orifice, you shouldn't have to worry.

hi all
thats right wireless is safe
but i really dont want to carry my mobile in my trouser pocket.

Yes, your average home Wi-Fi gear is probably safe. Have their been any studies on phased array antennas, such as those used by the just-approved Vivato?

Whether Wi-Fi enabled or not, it is probably wise to keep your laptop off your lap. We know what happened to one unlucky male researcher. Future chips are supposed to emit heat equivalent to a lightbulb. There is a startup company working on government research which does a better job of cooling laptops.

You can tell your better half the wlan is no more dangerous than a 2.4GHz cordless phone.

What's the difference? We're all going to die anyways.

put it this way, your cell phone probably puts out around 5-50 times the energy that your access point does, and they can't find any real dangers from them either. Your local TV station probably outputs 5,000,000 watts EIRP, with I believe 100,000 watts of actual transmitter power, if anyone is concerned about getting cancer, I would go hassle them. They have people that work right underneath those things, and I have yet to date hear about any ill effects.

ok, but 2.4 Ghz are microwaves, like a microwave oven, so what happen if you put a 1 watt or 5 watt amplifier with a 24 dbi grid in a metal box with an egg. Does it'll cook? Microwaves ovens delays 20 seconds to cook an egg, They have between 600 and 1200 watt. I imagine an egg will be cook in 2000 seconds. Does anybody make that experiment???

When I talk with my cell phone after 15 minutes I fill a bad headache so now I'm using a hands free. I don't want be a percent of the cancer stadistics!!

I'd say the risk is no greater than sleeping next to any (EMF-emitting) electronic alarm clock.

I can assure you your headache is not caused by the RF emitted from the phone. It might be associated with the phone being pressed against your ear, creating pressure, or might be some noise emitted from the speaker of the phone that you can't here. I've heard stories of navy/marines standing in front of the radars on ships to get warm on cold mornings, haven't ever heard of them developing headaches or brain tumors from it. My father worked on radio towers, he routinely climbed past antennas radiating various frequencies, sometimes at over 100,000 watts, and has suffered no ill effects. I have lived underneath a radio tower for 22 years, and I'm in perfect health. I've had a cell phone for the past 12 years, never experienced any ill effects from it. I don't have any actual statistics, but I'd guess there are somewhere around 50-75 million cell phones in use in the US alone, and not once has anyone been able to even partially prove they are linked to any type of health problems. If I were you, I'd be much more concerned with a drunk running a red light and plowing into me, i'd say your chances of that happening are 9999999999999 times as likely as you developing cancer from a cell phone, or wireless lan. There are many many other things that are worth you worring about, Like a satellite falling from the sky and landing on your house, or cosmic radiation from a gas giant, or nuclear radiation from your local power plant, or all of that EM energy that electron gun sitting in front of you is throwing out. Now, I'm sure that the state of california will eventually link cell phones to cancer, but then again, I think the state of california has linked pure water to cancer.

I don't think so. Eggs "cook" when it reaches 70 Celcius (? Farenheit). Unless you insulate it very well it will never reach that temperatur no mather how long you keep radiating it. :-)

Hello budies read this article:

Non-ionizing radiation is very different. Because of the lower frequencies and reduced energy, it does not have the same damaging and cumulative properties as ionizing radiation. Microwave radiation (at 2450 MHz) is non-ionizing, and in sufficient intensity will simply cause the molecules in matter to vibrate, thereby causing friction, which produces the heat that cooks the food.

This is a controversial topic, although the best science seems to be that non-ionizing radiation is not harmful in anywhere near the doses that one receives from wireless access points, cell phones, etc.

The FCC which regulates the permissable RF exposure to humans from transmission facilities has several informative documents on the subject.

See:

FCC document, Bulletin 56 Questions and Answers about RF Fields (http://www.dep.state.pa.us/dep/deputate/airwaste/rp/Radiation_Control_Division/oet56e4.doc)
