I would think an air tube headset with long extension cord might be a safer bet. (How would you paint your cell phone ?) Cell phone radiation is quite strong locally and would probably easily penetrate a 60 dB barrier. --- In [hidden email], Ole Alstrup <alstrup@...> wrote: > > Hello Emil, > Â > Thanks very much!

My query was for reducing or blocking outside radiation from cellular towers and communication. Are you saying that Y-shield
paintings with a screening reduction between 43-45dB is not sufficient?

Windows are more important than walls. I did my bedroom in the paint & didn't work. Someone here said you cannot use it as a faraday type cage. Best uses on bocking a wall and ceiling I guess. Not sure the technicals behind it but perhaps someone can comment on.

Sorry my misunderstanding-- your email mentioned:
"radiation shield paints that can block radiation from mobile phones" I meant to warn that 45 dB may not be enough for mobile phone radiation. For outside cellular towers and communications, though, it is weak enough that 45 dB is probably enough, if done properly. Just be aware that radiation shielding paints may spread electrical fields. I suppose grounding might help, but some others on this forum seemed to mention things getting worse after they painted with conductive paint, even when they turned off the electricity. Personally I prefer something less permanent than paint, so that if I make a mistake, I can remove it. --- In [hidden email], Ole Alstrup <alstrup@...> wrote: > > My query was for reducing or blocking outside radiation from cellular towers and communication. Are you saying that Y-shield > paintings with a screening reduction between 43-45dB is not sufficient? There are some real life examples in the pdf document > at http://www.yshield.com/pdf/YSHIELD-EN-ShieldingPaints.pdf > > From: emraware <emraware@...> > >To: [hidden email] > >Sent: Wednesday, 4 May 2011, 2:56 > >Subject: [eSens] Re: Radiation Shield Paints > > > > > > > > > >I would think an air tube headset with long extension cord might be a safer bet.

Re: Radiation Shield Paints

This is slightly worrying as I am currently in the process of painting my bedroom! Is there anything that can be done to guard against the spread of electrical fields in a painted room? I have already grounded the paint, and am covering the floor with aluminium insulating foil (under the carpet) to prevent radiation from coming in from below. My window has protective film on it and I am also buying some aluminium blinds for a bit of extra protection.
Obvously I have not spent any length of time in the room yet as it is not finished but I am hopeful it will give me an area of relative calm for when I'm asleep at least! Any extra advice would be welcome... Paul --- In [hidden email], Ole Alstrup <alstrup@...> wrote: > > Thanks for the clarification and the extra info, greatly appreciated!

If you are making a complete enclosure,
and all the shielding is grounded to the same ground, AND you don't have live electric wires INSIDE the shielded area, then the electric potential will be equal on all surfaces. You will have no electric field inside, regardless of voltage on the ground.

I agree with Emil. If there are any penetrations by wires you
need to have a filter right there grounded to the shield, with no leaks in the shield. Small holes are OK but no penetrations or long gaps or cracks.

Cheers for the advice.
One thing, when you say 'penetrations' do you mean plug sockets? Or are they ok to be left uncovered?

What you don't want is a hole in the shield with a wire going through the
hole. If you have an unshielded outlet there will be leakage. Ideally any holes should be less than 1/2 inch. The best way with outlets would be to use metal junction boxes and compression fitting to metal conduits to a filter. They used to make metal covered outlet covers for outdoors. If the outlets are live, think safety first.

Could this be why I can't sleep in my bedroom. I have the Y shield paint plus the window shielding Have the paint grounded by a metal strip that goes all the way around the room to the the outlet.
But no cover on the outlets. Just seems like a little area to cause my so much pain????

Grounding to the outlet might not be good from the
point of view of EMFs (it does add safety in the event of a hot wire touching the paint, especially if the wire is big enough so the breaker will trip). The outlet is connected to the power company at your panel (unless you've gone to an isolated ground system) so it has dirty power on it. There is a ground rod probably at the panel but that's not very low impedance at all so it doesn't get rid of all of the high frequencies (not even all the low frequencies probably). A painted wall has some some intrinsic capacitance, and could also have conductivity or capacitance to ground. Try holding your AM radio near the ground wire. If you pick up a buzz, or even if the radio stations suddenly are received at new frequencies, they you've created a ground path. A big choke in the system might help. If there is very good conductance to ground from the wall you can safely remove the ground wire. But usually to get it that good you have to install several ground rods 8' apart and have good soil. If there is nothing electrical that can possibly touch the paint, remove the wire and see if that feels better. You have to do something about the outlets and the wiring. Y-shield paint will not block dirty power frequencies. Maybe you can disconnect hot neutral and ground at the panel for that circuit. There still could be capacitance between those wires and other wires. Are all electronics unplugged at night?

Suppose you were to (A) Plug in a lamp (ungrounded) in a completely shielded, grounded room (doesn't matter if it's on or off, it still has electrical fields if it's plugged in) (B) Stand on your grounded floor close to the lamp. Since you are a conductor, some of that electricity from the lamp may now ground through you. To lessen this effect, maybe the following would help? (a) Grounding any electrical sources like the lamp that are plugged in the room so they have a path to ground other than you (b) Insulate yourself from being on a conductive path to the room just as an electrician should wear rubber shoes to avoid being on the path to the ground when working with electricity? e.g., with nonconductive furniture (unfinished wood bed frame for example) Anyway, I don't know if any of these suggestions will actually help... but just food for thought. --- In [hidden email], Bill Bruno <wbruno@...> wrote: > > Grounding to the outlet might not be good from the > point of view of EMFs (it does add safety in the event > of a hot wire touching the paint, especially if the wire is big enough so > the breaker will trip). > > The outlet is connected to the power company at your > panel (unless you've gone to an isolated ground system) > so it has dirty power on it.

Re: Radiation Shield Paints

Right, thanks for the info guys, I'm officially getting worried now! lol. I guess I wont know for sure until I actually finish the room and spend some time in it. I still have one wall to paint, which is and internal wall that does not face outdoors or either of my neighbours. I'm wondering if it might be worth keeping this unpainted so any stray microwaves bouncing about can leve he room without entering my body? Just a thought, what do you reckon?
Really I just wanted to protect from outside microwave radiation and that's what I painted those three walls first. I might do some tests before I finish the job. This is a real minefield though, the last thing I want is to feel worse after shelling out so much money on it! --- In [hidden email], "emraware" <emraware@...> wrote: > > > Suppose you were to > (A) Plug in a lamp (ungrounded) in a completely shielded, grounded room (doesn't matter if it's on or off, it still has electrical fields if it's plugged in) > (B) Stand on your grounded floor close to the lamp.

Hi Bill
I was reading this and wanted to ask you: If I hold the AM radio to the earthing rod (going into the earth, that I've grounded my faraday cage to) and it has a buzz, what does that mean?

And it means that the rod may bring *dirty power* into the house.
