| [Notebooks] Laptop EMF and health concerns with Wireless
I spend so much time in front of my laptop that I am a bit concerned about the health risks of being constantly in close contact with the emf (electro-magnetic fields) emited by the laptop, especially with the wi-fi turned on. Of course, the verdict is not in yet whether there are actually health risks, but I figure better safe than sorry. While I am at home I keep the wi-fi turned off and use networking through the electrical outlets. I only turn on the wi-fi while out and about.
I have scoped out some emf detectors and have thought about buying one to get some idea about how much emf is actually being emitted from the laptop with and without the wi-fi enabled. Also, there are some companies that sell metal sheeting that supposedly blocks emf. I was thinking about getting some of this and putting it under my laptop, especially when I am working with it directly over my lap.
Does anyone have experience with emf readers and emf blocking products?

| The WiFi card in your laptop receives signal, not send it, further, it receives that signal through it's antenna, which runs along the frame of the LCD, not on the bottom of the notebook.
Since you do not receive signal through electrical outlets I assume that you mean you ethernet cable directly to the router, yes? If it is a wireless router, unless you turn off the SSID broadcast through the router set up, it is emitting the exact same signal, regardless of whether you notebook's WiFi card is on or not.
Any emf through WiFi is so minimal as to be inconsequential. there are literally hundreds of sources of emf that you are exposed to daily far, far in excess to this, but to each their own

Ok you got me curious on this one. How does a WiFi card not send signals? I thought it had to broadcast outwards when you send email, click links, chat messages, or anything you have to upload to the internet or across your network.

Far as I know it isn't a real issue.
Being that you are being exposed to emf & RF we don't really have much choice.
So I hope you use this prototype enclosure to help you deal with all these issues.
Seriously, I wouldn't loose sleep over it you will get cancer before you die from emf or RF which you don't have any control over.
Pictured is a sample of what you can do 
I am sure you can find instructions on google how to build one.  |

Ever see a touch lamp? The work on the inductance that is vibrating your body.
Do you have a stereo? Plug an RCA cord into it.
Turn up the volume a little and then touch the center conductor of that RCA... hear that hum?
That's you!
The inductance from the wiring in your house is doing that.
If you have a boombox with input on it, it will do the same thing.
Now, if you run the boombox off of batteries and go out and kill the Main Breakers for the house and try it - you may get the initial pop of you touching the input but no hum.
Ok, got Cellphone? They are more powerful than any laptop's WiFi.
WWAN(cell enabled) laptops are just like a cell when the WWAN is on.
Dude, what I'm getting at here is that WiFi is pretty much harmless.
I have 3 (three) wireless laptops and a cordless phone.
In that same bedroom, I have two cell phones and a wireless router for the laptops.
I am also "seeing" wireless from several neighbors.
EDIT: Yes, the wireless card/antenna in the laptop(when switched on/being used) is transmitting...

| My concern is that there are no long term studies that show whether or not the emf from a laptop and / or Wi-Fi radiation have any health risks. In the 40's and 50's they used to drive down suburban streets spraying DDT and the kids would come out and play in the fumes. I'm sure back then the scientists assured everyone that DDT is perfectly harmless.
This definitely isn't something I lose sleep over. But, if I can prevent cancer 20-30 years from now by simply placing a sheet of material under my laptop that blocks emf and radiation from directly entering my body, it would be worth it. |

Duh...yes...must've been a "senior" moment 
However, the rest stands...the antenna through which the signal is received/sent is not in the base of the notebook, but rather along the LCD frame. A "shield" on the bottom of the notebook would be of no value.
Besides, as dadkins mentioned...if you use a cell phone, little point in worrying about your WiFi
BTW, I grew up in the 50s and 60s...DDT was still common, even then, nobody I ever knew went out to play in the fumes...that is just too funny!

Every minute of every day, you are being exposed to some sort of emf - as I explained earlier.
If your house has wiring that has power going through it, you are resonating with inductance.
If you turn on a radio, it will most likely tune in more than one station - on several bands.
If a public service vehicle is ever within 50 feet of you and they key up the mic, that will scramble your TV.
Our whole continent is being "cooked" by satellites using microwaves.
laptops are low power. Don't trip!
If what you are worried about were true, I should be a pile of ash by now...
I have used wireless devices for 30+ years.
From walkie talkies to cellphones to 2 meter radios.
Typing this from one of three wireless laptops in this room.
No worries!

Ok gotcha, screwing with notebooks is still new to me and thought something new may have slipped my radar.
I'm not worried about EMI myself though. If that were my case I wouldn't have an unlimited cell phone plan.
