Making an EMI radiation shield for a laptop?

Here's a bit of an interesting idea. My wife uses a laptop on her lap. She is a bit anxious, complains about ringing in her ears, anxiety, rapid heartbeat on occasion. I never used the laptop for more than a few minutes before today. After 30 minutes, guess what? My ears started ringing and I felt anxious and not well.

So can this be attributed to EMI and wireless radiation concentrated? What can be done? Wrap it in ERS paper or make a EMI shield by wrapping a laptop cushion or lapdesk in copper tape and setting the laptop on it?

I see products under laptop radiation but they are all slabs of something and cost $80? Seems a bit silly imo.

Placebo effect. You probably started feeling weird and anxious because that is what you were waiting to happen. It was probably something else making her feel weird and anxious. Now you both are worked up over the idea of it being your laptop.

It isn't the laptop.

If you are really that concerned about it, use it on a desk and with an external keyboard/mouse if you really want.

It isn't the laptop.
 
Drink less caffeine. Will lessen the anxiety and lower your heart rate.
 
Nope. Not usually anxious. Don't drink caffeine much. Usually herbal teas in winter lol.

I have a resting heartrate of 65 and can run all day. Pretty mellow generally. Maybe it is more than that but we did have the same reaction.

Anyway ordered this:

LapGuard with Radiation Shielding Technology

Figured what the hell. Cheap enough and it at least keeps the laptop cooler.

There is currently 0 credible scientific evidence that humans are affected by EM radiation of the sort a laptop would put out and it's likely there are greater sources around you that you don't even know about, they don't affect you because you don't know about them.

Working on that too. Something is going on in that room.
 
does she watch TV?

does your home have wifi?

has she ever used a cell phone?

all of these day to day things emit the same sort of RF energy - the laptop is not the cause if she can use or do those other things with no issue.

Worst case -- build her a Faraday cage to live in - make it pretty big though, gotta have room for sexy time.
 
Please don't get taken in by quacks. There is nothing going on besides a warm lap due to a hot laptop and most poeple have a touch of tinitius that you would notice after you are used to the sounds in a room. Put a TV stand dinner tray on your lap to provide better air flow and lat the laptop (and your lap) stay cooler (and not have the laptop fan whine in your ears!).

Read it and read it again.

I experienced the same thing since two months nearly with a specific laptop
some of my friends felt the same thing when they use it,
I'm not sure if it is caused by radiation or not, but I think this is not an illusion as somebodies say,
A scientific proof? science is not closed yet, we can't deny something happening because its not yet scientifically proven
 
I think the problem was a caused by a wireless mouse/keyboard
I removed them, and its ok now
 
IT IS NOT THE LAPTOP OR ANY OTHER WIRELESS DEVICE. End of story, no debate, no question. ALL properly studied evidence says this, please don't fall for this crud.

Who funds the studies? A study on the health effects of wireless devices doesn't mean shit if it was funded by a major wireless company, for example. Money trumps everything else in this world, now that is something that cannot be debated.
 
There is evidence that wifi, because it is a UHF frequency which is IONIZING, can do damage over time to stem cell and dna replication (I also have my Major in Cellular Biology). At the levels of radiation the laptop puts out and as an adult you are virtually unaffected. However, your infant shouldn't be next to your cell phone or sitting on your wireless gaming laptop all the time.

However, if it makes you comfortable, I am an FCC licensed US Amateur Radio operator, and we do use UHF frequencies in the 440mhz range all the way to 2.4ghz and beyond. We use power levels in excess of 50 watts and some of us push 1000 watts + up to 1500watts legal limit. We are also required to understand, in order to get licensing, the dangers of RF radiation to humans and animals. Your laptop is sending out an RF field of about 250mW that is 0.250watts of power. So a fraction of a fraction of power that HAM radio operators utilize. You are MORE than safe. Let me rephrase this ... MORE than safe.

This is a peer reviewed study that indicates that wifi and RF fields are dangerous to young developing peoples.

I agree with what you're saying as a whole, but I need to point out (since you put it in caps) that the type of radiation that comes from a laptop is not ionizing radiation, but instead NON-IONIZING radiation. Any commercial RF (wifi, radio/tv broadcasts, satcom, etc) is of the non-ionizing variety.

Examples of ionizing radiation (aka stuff you don't want to be exposed to) are x-rays, gamma rays, etc.
 
I once got a laptop to have electricity run through the metal parts of the laptop (on the outside) after it fell a few times in airplane transport. Maybe it's something like that.

Studies get funded yes, but any scientist would love to prove it due to the press and fame they would get. Don't be taken in by such sentiments, there are places that large companies are after things such as copyright law and political agendas, this however is not one such topic.

I'm sorry but it does not take a deep understanding of the science behind electromagnetic radiation to understand what is going on, it's just a sad statement on the general science literacy of America and the UK that people get taken in by this stuff.
