Re: Chickenwire may block EMFs

[Guest guest]

Funny, how differently people see things. I'd love to have his problem: He

can't get any wifi or cellphone signals. Turns out chicken wire is like

'kryptonite' for emf's:

I would be tempted to put chickenwire around my bedroom but couldn't metal

attract lightning? I'm on a hill top.

The article says it reduces signal 33% to 75%. That can be significant but it is

not blocking it. Should be sufficient for most but not for everyone.

Article didn't say it completed blocked but sig reduces to the point where

people have trouble using their cellphones inside their homes, freq need to go

outside on a balcony, etc, to use, and trouble using wifi even in their own

space, let alone getting signal from outside their home. My reading was that

blockage was more significant. I think people that get some reception may be

standing some place where signal does not have to go through chicken wire, like

remodeled room with drywall in it, or near a window. I'll reread it but I

thought it said openings in chicken wire were small enough to cause trouble with

almost any signal.

Grounded chicken wire may have some shielding effect on electric fields

(V/m), but it will not effectively shield against magnetic fields (Gauss,

Tesla) or radio frequency radiation (W/m2). A finer metal mesh would be more

effective. Setting up shielding is a complex science and if not properly

designed or tested may actually do more harm than good. Often times people

unintentionally create antennas rather than shields, and during mitigation

simply undoing their efforts reduces EMF/EMR significantly. Be careful, and

seek professional advice if you have any doubt.

There are metal impregnated paints, window films, and fabrics specifically

designed for blocking extremely low frequency (ELF) electric fields.

www.SafeLivingTechnology.com and www.LessEMF.com have a good selection.

But again... use with caution. A Certified Building Biology Environmental

Consultant trained in EMF inspections and mitigations would be useful to

help you figure out what's present in alarming levels and layout the most

effective approach to mitigation. (

When most people think of " EMF " they think of magnetic fields as measured in

milliGauss or nanoTesla. Chicken wire will have nearly zero impact on

ambient low-frequency (60 Hz) magnetic fields.

Stay well,
