No, not lead. Lead stops nuclear radiation, it doesn't help much with RF, which is what he says his problem is.
But THIS is the shit hot ticket. Failing that, there is some pricey RF shielding paint. It may prove less expensive than a Faraday cage or other RF tight 6 sided enclosure.
If you have any friends in the aerospace or defense business, they can probably point you further in the right direction.
A cage mainly shields against the electric field, but not the magnetic field. Plus the cage is only good for the frequencies its designed to shield, so best to line his whole room with a continuous metal surface so there is no potential difference and so he is completely shielded electrically. For the magnetic field, he'll have to redirect the magnetic field with an outer skin of magnetic material with high permeability. If anything, a tedious application of Maxwell's equations will surely give him a good nights sleep- it always does me.
We are talking about waves here, aka oscillating fields, not static. If one day you manage to read the equations without falling asleep partway, you will find that oscillating E and B fields are coupled together (see the Faraday and Ampère equations). If you kill the electric field, it's going to cancel the magnetic field too.
Being a "professional" doctor of physics, not medicine, it's a bit out of my area of expertise. But, in a case of self-diagnosed electro-sensitivity, wouldn't an homeopathic treatment be just as effective as living in a Faraday cage to treat the "symptoms" ? It would be much cheaper and more convenient, with the added bonus that any homeopathic medicine would work just as effectively regardless of whatever is written on the label.
It was just a joke. Sorry if it came out pretentious or whatever. There are a lot of "doctors" on this forum, and even more people who understand that a doctorate isn't a good proof of neither smarts nor mastery of a field of knowledge.
I don't see where you are going with this, but no. I never said the waves were generated without moving charges. Antennas create waves by having an oscillating current going through them. All I am saying is, you can't have variations of the electric field without the presence of a magnetic field (because of the Maxwell-Ampère equation) and vice versa (Maxwell Faraday). Therefore, if you shield yourself against electric fields, you are also shielded against the magnetic field from the wave. That's because the latter cannot exist without the former. This is the reason why we always talk about electro-magnetic waves, and never about electric waves or magnetic waves alone.are you saying the waves from the wifi router were generated without moving any charge around inside?
My Maxwell equations=a good night's sleep was supposed to be a lightheaded joke but instead became a way for you to let me know that if I could pay more attention then I could have as good as grasp as you on electomagnetism. Then your next line is that you have a doctorate in the subject. Wound me up a bit, I admit- correcting me without telling me I clearly haven't the capacity to understand Maxwell's equations would have been sufficient.
As for the current, I was clutching at straws to suggest that a steady current before the oscillator would produce a magnetostatic field which would penetrate a Faraday cage and induce currents in a moving body within. However, that would be true of all his electrical equipment and is just getting silly.
Thanks for the explanation, anyway. I'll bear it in mind if I ever resume my degree.
