Extreme Low Frequencies Radiation Protection is very limited. Since the frequency is low, and the magnetic field tends to penetrate most materials, we can use protection only in several main scenarios.
Before we start
Before installing EMF Protection you need to measure the EMF
and to find all sources and penetration points.
Using Radio Frequency(RF) emitting devices inside a protected area should be avoided!
ELF shielding should be used to keep the ELF from outside entering your house. Most types of ELF Sheffield will block and reflect also RF radiation.
If you use RF emitting devices inside the shielded area you risk that the RF will bounce back from the shielding. Therefore, when ELF shielding is used, we believe you should not use any wireless devices inside the shielded area.
DIY EMF/EMR shielding should be done only by those
who have the knowledge and on their own responsibility
Extreme Low Frequencies Radiation Protection
Because ELF fields tend to overpass obstacles, the ELF protection has to be much bigger than the size of the source, so when the ELF field will eventually pass it they will be very week. Before installing the ELF protection you need to design the protection according to the type of source and the structure of the rooms. Since some of the ELF magnetic will pass the protection, it is recommended not to place sitting or sleeping area right next to the protection, but to keep a safety distance of at least 50 cm from it.
ELF(Extreme Low Frequencies) blocking foil
This foil is very flexible but very expensive (expensive compared to RF blocking foils and also to other ELF shielding material). On the other hand, it is very easy to handle and can be trimmed by a pair of home scissors. It can be applied on walls and needs to be grounded. It is usually used as additional protection after ELF blocking metal panels or when there is a need for a small, light and flexible solution. This foil is used usually to block ELF magnetic fields in medium and low levels of between 20-2 mG. For higher levels, you need to apply to lairs of this foil or to use additional metal plates.

ELF blocking metal plates
The ELF magnetic fields blocking metal plats are similar to the ELF blocking foil, but they are not flexible and usually used only in the professional market. In order to install it and to apply it on walls, you will need to drill holes and to screw the plates into the wall, ceiling, and floor. The plates are heavy and are made from a verity of metals with different magnetic characteristics. There is usually the need to use several layers, each on with different magnetic polarization. Some of the materials blocks and some observed the ELF fields. These plates are more expensive from the ELF blocking foils and are usually used to block high magnetic fields between 20-200 mG and more.

ELF active protection system
ELF blocking Active systems – used in order to block a low-frequency electromagnetic radiation field and to lower its level in a given point, but this is done by creating a second field in the same strength and in opposite direction to the one that was already there. In the point in which both fields are in the same strength, you will be able to measure magnetic field of 0 mGause, but if you move towards one source (ELF original source or the active ELF blocker) the ELF levels will go up, they will still be lower than the original ELF source levels, but now they will be a mathematical sum of the two fields which are in opposite directions. This active system does lower the measured levels but I don’t think this actually reduces the health risk. I think it might even increase it since now your body is exposed to more fields from several directions.
We don’t recommend using an ELF active protection system.
