Preview to RF protection products and techniques

In this page we will review several products and ways to block Electromagnetic non ionizing radiation in radio frequencies, also known as RF EMR. In RF EMR, as the frequency is higher it is easier to block the EMR. Please remember that blocking and protection is the last step and before applying it you need to eliminate all RF sources in your house and conduct several RF EMR measurements in the house to identify the sources outside the house causing the high levels inside the house. If, for example, your neighbored is using a RF emitting device, I suggest trying to talking out of using the RF device (at least try to) before trying to block it be applying RF blocking paint on the wall between your and his apartments.

 RF blocking fabrics

There are several manufacturers of RF blocking fabrics. I am not familiar with any ELF blocking fabrics. As explained before on this site, while it is easy and cheap to block RF EMR, it is very complex and expensive to block ELF.

I tried several types of RF blocking fabrics and each one was different in the frequencies it can block and to the extent it can do so. If you want to buy these fabrics, first try to get the characteristic charts of the fabric so you can see which frequencies it can block and to what extent.

I use these fabrics mostly as a cheap and portable way to block RF from penetrating office walls so I will be protected at my work (as much as possible). It can be applied to the wall and then removed, fairly easily, if needed. It is possible to get these fabrics in different colors so it will be similar to the wall's original color. I also carry these fabrics with me when traveling and use them when staying in hotels. Some of the fabrics are see-through and can be used as curtains or as bed canopies.

RF protection clothes

Some people think and belive that the human body itself is a source of EMR. In some cases it would not be a good idea to wear clothes that block the body's own EMR. In addition, as said before, each person is different. An RF blocking fabric can help one person and in the same time it will not help the other.

It is possible to get several types of clothes that are made from RF blocking fabric. These RF protection clothes are sold around the net and are usually expensive. I tried to wear these fabrics (costom made) on my body but felt no drastic effect. For now, I decided not to wear these RF protective clothes, except from the RF protection hat which I wear daily.  I might try wearing them again in the future.

RF Protection hats and caps

A few years back I bought an RF protection hat on the web. It was expensive (~US$35) and my experience was that it had no drastic effect. A few other EHS persons reported that it helps them more than it helped me.

A year after, I created an RF protection hat from shieldon© RF blocking fabric and later on, I created a few more hats for me and several other EHS friends, most of them reported that it helps them. I was able to show that  the hat is blocking RF EMR with RF meters I have in one of my videos.

My experience with the hats I made myself is that they are very helpful. I wear such a hat every time I go out, and most of the time at work. It allows me to function better when the RF sources are above me (WIFI routers, Cellphone masts and so on). It does not protect from RF sources that are below you.

RF blocking paint

Some building materials (like concrete) block up to 90% of the RF radiation. For other material that don't block RF as good as concrete, or for cases that the RF levels are so high that some of it manage to pass the walls of your house and get into the rooms, it is possible and recommended to use carbon based RF blocking paint.

RF protection paint can be applied on internal or external walls. The paint itself is a conductor and if applied correctly (and when grounded) will create a barrier that will block most ( more than 90%, depending on the type and brand of the RF blocking color and the frequency of the RF EMR) of the RF coming into your home. The price of these paints is usually expensive but this is a solution that will last for years. The color is usually black but you can paint over it with any color you like.

The paint should be applied on all the external walls of the house (from inside or outside). It is also possible to use the paint on the ceiling. If you live in an apartment building, you should also find a way to block RF EMR coming from the floors below and above you and from apartments beside you. Sometimes it is sufficient to apply it only on the wall facing the external RF radiation source.

None of the available paints were tested by me up to this moment, but I hope to do it soon. Other people reported that the carbon paint is very good and it does the job.

I don’t think it will be wise to apply this paint (or any other RF blocking technique) on your home's walls and then to use wireless or cellular equipment inside the house. 

RF blocking canopies and mats

If you are surrounded by RF EMR even in your bedroom you might want to use this product. The RF blocking canopies are very expensive but they will allow you to sleep in an RF free environment even if your bedroom has some RF EMR.

Coupled with an RF blocking carpet, to block the RF coming from below floors and apartments, the canopies will block most of the RF and will leave a clean RF free environment inside it.

Please never use RF source inside the canopy, this may result in exposure to high levels of RF EMR.

The canopies are made from an RF blocking Net cloth that allows fresh air to penetrate the canopy.

RF blocking window's curtains

Another way to stop the RF radiation from coming into your house via the windows is to install RF blocking curtains. there are several types of fabrics used for these curtains. each type of curtain has diffrent charactaristics. The bigest advantage of these curtains is that they can be taken off the walls, washed and reinstalled in diffrent location (in case of moving to a new apartment).

RadBlocker Microwave © (RF) blocking kit 

I don’t like microwave ovens. They warm and cook food really quickly but it is not exactly cooking and it warms the food using microware (2.4 GHz RF radiation) radiation. Microwave ovens use ~500W microwave tubes that transmit very strong 2.4GHz RF/WM radiation.  Most of the RF/WM is blocked by the oven’s cover and door but still high levels of RF EMR (similar to the levels that are emitted from a GSM cellphone) are emitted from the door while the oven is working and even if and when it is 100% OK.

If you still want to use your microwave please never look inside the oven and be sure to leave the room when the microwave oven is working. When my wife uses that microwave oven (about once a month) she leaves the kitchen room and I leave the house. The only use we still do with the microwave oven is to sterilize the baby's dishes and to make instant popcorn.

The best way to block most of the RF radiation emitted from a microwave ovens door and sides is to put it in a built-in wooden cabinet and to cover the sides and door of the cabinet with RF blocking material (leave some space for air for cooling).

If you don't have a built-in wooden cabinet you can try and put RF blocking film on the micro or use the RadBlocker microsafe  © .

The RadBlocker Microsafe © microwave RF blocking kit can reduce the RF radiation emitted from your working microwave oven; however it does not reduce it completely.

This small kit will allow you, after a short installation, to block some of the RF EMR coming out of your microwave oven. As I showed before in my videos, every microwave oven, even if 100% OK, still emits high levels of RF EMR. This product can be easily taped (better not to use the stick on magnets, but to tape cover) to the door of your microwave and block some of the RF EMR that escapes the metal net on the microwave’s door. 

As I said, The RadBocker Microsafe © kit does not blocks all the RF radiation coming out of the microwave oven, but it does block some of it. In the last few weeks I have been testing this device and I am working on a video clip that will show the kit in work. It takes me a long time since I get a big headache after each test.
