Low-frequency EMF Meters

Low-frequency EMF refers to the very bottom end of the electromagnetic spectrum, well below radio frequencies.

In our daily lives, low-frequency EMF is very pervasive, for one reason: our mains electric power falls within this range, with a frequency of 50 or 60 cycles per second (depending on country).

Low-frequency EMF has one peculiar quality: the magnetic portion and the electrical portion behave differently, and can be measured separately.

Some EMF meters measure both magnetic and electrical fields, others just measure the magnetic field. The latter are sometimes called Gaussmeters, because Gauss is one unit of measure for magnetic fields. (The other unit is Tesla.)

The magnetic field is thought to have more relevance for our health because it is capable of penetrating a person’s body, whereas the electric field has no penetrating power.

Low-frequency magnetic fields will pass through just about anything, including rock, concrete, brick walls and steel, so they have no trouble going through a human body – bones and all.

There are a number of very cheap meters in this category, but their sensitivity is usually poor, and accuracy may not be great either.

We have selected a few that we think are of good quality, and in the case of the Tenmars TM-192, we have used this meter for professional work and can recommend it.

Cellphone Protection Pouch

A Cellphone Protection Pouch is great if you like to carry your cellphone in your pocket, like I usually do.

Cellphones communicate frequently with the nearest mast, even when you are not using the phone. This creates an EMF from your phone which travels in all directions, including through your body.

Not all pouches work in the same way. The ones I prefer shield you from most of your cellphone’s radiation while you are carrying it, but you can still receive calls and messages. As long as the phone is in the pouch, its radiation only travels away from your body, not towards it.

Some pouches offer the option, either to screen radiation in all directions (phone will not work) or just shield your body from the phone’s radiation (phone is still able to receive and transmit).

These pouches have two compartments, and you can carry your cellphone in either one. In the inner compartment, the cellphone is surrounded by radiation screening material, so no signal reaches the phone or escapes from it. This means your phone can’t receive messages or calls. (It may try to transmit, but the radio signals won’t escape the pouch.)

But when in the outer compartment, your cellphone is screened on only one side – the side next to your body. Now the phone can still receive and transmit via the unshielded side of the pouch. So your cellphone is still functioning, but you can carry it safely. You can answer calls as usual, just slide the phone out from the pouch first.

There are several varieties to choose from. Here are some of the ones we like best.

Pity they don’t sell it by the yard!  What to do with 55 yards?

Our comments:

You could use this product like wallpaper to screen radio-frequency electromagnetic radiation. Get an expert to hang it for you if you haven’t hung wallpaper before – it’s not as easy as it looks!

Claimed attenuation is a very high 80 dB at 1 GHz – other radio-frequencies are not specified but will probably be similar.

No customer reviews on Amazon at time of writing, but the Amazon description implies a high-quality item.

The product is sold on Amazon in various shorter lengths, too.

Suppliers suggest using a special dispersion glue called DKL90 to attach the product to the wall. This glue does not appear to be carried by Amazon.

You would probably only consider hanging this on the inside of a wall, because it would not be weatherproof. Also it might not look very good in your lounge – so perhaps you could hang a more decorative wallpaper on top of it.

What I know about decorating is dangerous, so you might want to consult a decorating expert, unless you are one!
