Re: Re: Shielding with rescue blankets

[Guest guest]

Hello Nikolaj,

no, chicken wire is not good enough, the meshes are too wide.

The least is the socalled *voliere wire*, here the wire is 0.8 mm thick, and

the openings are 12 x 12 mm.

Normally, the rescue blankets shield ca 40 dB.

With your HF meter from ia, you cannot measure dB.

You read dBm. That is something different.

And 15 dBm difference is quite a lot, depending from the number !

As an example, if you go from - 20 dBm to -30 dBm, that means from 1200

uW/m2 to 120 uW/m2, that is a hell of a lot reduction.

If you go from -43 to -53dBm, you got from 6.1 uW/m2 to 0.61 uW/m2

If you go from -51 dBm to -60 dBm, you got from 0.96 uW/m2 to 0.12 uW/m2

Otherwise, in a livingroom the max is -30 dBm (= 120 uW/m2 = 0.21 V/m) and

in a bedroom -51 dBm (= 0.96 uW/m2 = 0.019 V/m) is preferable.

Sorry!

I consider shielding my home, at least the bedroom to decrease present

RF

levels from nearby mobile base stations etc at 5-10 microW/m2.

However, I am aware shielding also decreases the beneficial influence

from

the natural EMF signals. Isn't that a problem when shielding? Can it be

prevented - e.g. by shielding only some parts of a bedroom (windows,

ceilings and may be walls and exclude shielding the floor)?

Hi ,

How come the chicken wire don't work, as long as the mesh size is smaller than a

half wavelength?

Hi Nikolaj and ,

of course chicken wire work!

Hello Nikolaj,

Chicken wire does something, but largely not enough.

I estimate something like 3-5 dB.

Those HF waves are very naughty.

They just fly through.

The hole smust be as small as possible.

The best is these fly-wire, but in front of a window, you won't see

anything.

I tried several materials, and in the beginning, I was satisfied with this

birds-wire of 12x12 mm opening.

But since they put extra gsm senders on top of the existing masts, (we face

some five masts) the radiation has been higher, and I was forced to place

other material in front of this wire.

You may look at ISPO Gewebe, or Armierungsgewebe z.B. Glasseidengewebe G-ES

at Biologa or Priggen.

Or the Diamant Gewebe from Biloga/Priggen.

Of course in front of windows, a transparaent film, like RDF is the best,

but it costs.

Therefore my advice for the thermo blanket in the bedroom.

It is the cheapest thing available.

Met vriendelijke groeten,
