Why can't I use cellphones and wireless devices while wearing RF Protection clothes?

posted Jul 10, 2017, 1:51 PM by Amir Borenstein, No Rad   [ updated Jul 10, 2017, 1:54 PM ]

Q - Why can't I use cellphones and wireless devices while wearing RF Protection clothes?

A - You should not wear RF protection clothes while using cellphones or wireless devices for several reasons:
  1. RF Protection Clothing are for EHS people. EHS people should not used cellphones or wireless devices.
  2. Wearing RF Protection Clothing is a last resort. Before buying and wearing RF Protection Clothing is recommended to stop using RF emitting devices.
  3. The RF Protection Clothing will block some of the RF (usually most of it). If the user use a wireless device while wearing it some of the RF will manage to get to the user's body. If the user is an EHS he will feel this radiation.
  4. We don't want that cell phone users or wireless devices user will buy our products just so they could silence their conscience. There are a lot of other products out there, that are meant for that.

What is the difference between dB and %, and what is a good number?

posted Jun 28, 2017, 2:29 AM by Amir Borenstein, No Rad   [ updated Jul 1, 2017, 12:44 AM ]

Q - in the fabrics' RF reduction info, some sites show the reduction effect in dB unit, some in %, your site shows both.
What is the difference between dB and %, and what is a good number?

A - dB is the bumping effect of in logarithmic nature.
It is usually used in professional RF protection since the difference between -0dB and -100 dB is very big. 
The following table is a conversion between dB and %

RF Reduction dB/%
 dB %
 -3.0103dB50
 -6.9897dB80
 -10dB90%
 13.0103dB95%
 -15dB97.5%
 -16.9897dB98%
 -20dB99%
 -30dB99.9%
 -40dB 99.99%
 -50dB 99.999%
 -60dB 99.9999%

Well I think that measuring in dB is highly misused when it comes to every day RF protection, specially in clothes and hats.
The use of dB units comes from the military and professional world of RF protection, where sometimes you need to go down  -90db or even lower.
In case that you have only one penetration point (happen in the military or professional world but not so much in the real world) then a protection material with -20 db will be better than one with -15db and much better than -10db. 
But in every day world, were there are many penetration points and the installation is usually not perfect, if you pay more for a  -50db (~99.999%), or even -35db(~99.97%) compered to a -25db(~99.7%) or -20db (that ~99%), I think that at-least in some cases it is a waist of money. 

For example, if you protect a car, and you don't protect the front wind shield (since in most countries it is illegal and because it can distort the road view, specially at night) then more RF will come from the front wind shield than the difference between RDF62 and RDF72, and the price for the RDF72 will be double. 

Second example, if you need curtains, and you install the curtains in a way that there are not glue to the wall or window (there is some air between them), then more RF will come in from this gap than the difference between -25dB to a -35db fabric. 

Third example, if you are looking to make a hat, more RF will come in to the head from the places you can't cover, than the difference between a -20db to a -30db fabric.

Why some people feel discomfort while wearing or using RF Protection?

posted Mar 31, 2017, 4:32 AM by Amir Borenstein, No Rad   [ updated Mar 31, 2017, 4:40 AM ]

Q - Hi, Amir, I see that you are dealing with some protective fabric... I myself don't like shielding as I feel the other kind of discomfort in Faraday cages and know others who have similar experience... Would like to hear what you say regarding that "other kind of discomfort"... By the way, mice in experimenst also avoid screened rooms.
D.C 31/03/2017

Some people feel discomfort because of several different reasons.
These are the reasons I come across so far:
1. Some are sensitive to the fabric - I think that other then in a hat, the fabric should not be on the skin (not as an undershirt or underwear).  I recommend my costumer to wear the Shirt, Jacket pants and ponchos over normal clothes and underwear/undershirts.
In addition I recommend to my costumers first to test the fabric, by getting the cheapest possible product and see how it goes. I sell RF protection lining/inserts for $15, this product can be a great test product.

2. Some people use the personal protection while still using RF emitting devices -  I recommend/ask not to use the hats and clothes while using wireless device. This first thing you do as an EHS person is to stop using cellphones and wireless devices, not buying protection.

3. Some use RF protection before reducing exposure first - I explain that first you need to stop using the cellphone and wireless devices. then use an EMF meter to find all sources in side the house, keep safety distance from ELF sources, remove all wireless sources, find penetration points of RF to your house and use the RIGHT (!!!) RF protection to block it (lots of people don't understand which protection to use in which situation and how to use it. These people will most likely make mistakes, like protecting the walls before the windows, like using the RF blocking paint inside the house - might cause reflections, or using RF protection at all before removing RF sources from the house. An other mistake is to connect RF protection to the electrical ground.

4. Some people use the protection with no understanding of RF - I explain that the personal protection should be used only to bring relief when exposure to environmental RF radiation such as cellular towers and WIFI routers which are installed above the user, and not for RF sources bellow the user (the protection is usually opened from bellow, so the RF that comes from bellow will enter it).

5. The Blocking effect is not 100%. Some RF will still be coming in from the holes and opening in the design and some people will feel that. So even if the personal protection helps, it will not be 100%. I recommend to try and measure the relief it brings you. For example, without a hat I feel pain (headache) in my living room after 5 minutes. With it, only after 5 hours or more. I can still feel pain after more than 5 hours, but that does not mean the hat is not working.

6. An addition thing might be that in most fabrics (not the one I am using for my hats and clothes) the RF blocking effect will be reduced after several washing. So people will feel worse and worse as they continue to wear the hat or cloths.

7. One more thing, the body creates it own EMF field. So some people will not feel good inside the RF protection clothes if the blocking effect is too great. I feet this too, and when it happens I just open the RF Protection Jacket a little bit. I know that when going to the city with the Jacket I will feel some discomfort after 20 minutes, but without it I will feel worse sooner.

Remember:
Protection, both personal and house protection is the last step.

Why only Electromagnetic hyper sensitive people should use the hats and cloths?

posted Mar 30, 2017, 12:11 PM by Amir Borenstein, No Rad   [ updated Mar 30, 2017, 12:11 PM ]

Q - 

A - The hat is for Electromagnetic hyper sensitive (EHS) people (Electromagnetic Sensitive people included) that feel pain when around RF radiation sources.
People who do not feel the radiation will not know that the hat is helping them and might use it incorrectly (like when using a cellphone while wearing a hat).
People who are not EHS/ES, will benefit more from exposure reduction, from using an EMF meter, from house protection than from personal protection.

Why are you using the SHIELDON 240 fabric in all your hats and clothes?

posted Mar 27, 2017, 5:16 AM by Amir Borenstein, No Rad   [ updated Mar 27, 2017, 5:21 AM ]

Q - 1. Why are you using the SHIELDON 240 fabric in all your hats and clothes, while there are other RF blocking fabrics that can block better than what the SHIELDON 240 fabric can.

A - The reason is that the SHIELDON 240 is the best fabric we have. It has a good blocking ability, it is very durable and will last for years
The SHIELDON 240 is the most durable fabric we know of.
You can wash it in a washing machine and it will not suffer any reduction in it's ability to block Radio Frequency radiation.
It will last for many years and will require no maintenance.
When you buy expensive RF protection clothes, using the cloths for many years is a big plus!
The SHIELDON 240 fabric has a blocking effect of more than  99% (higher than -20 dB tested for Frequencies of 10MHz to 3 GHz) which is enough for making cloths and hats (more RF will come in from the opening of the hat or cloth, than trough the fabric it self).
Other fabrics may have higher blocking effect, but they are not as durable and after several times you wash them, the blocking effect will go down, sometimes  for more than 50%, sometimes even farther down.

Will the S240 and S238 block Electromagnetic Radiation

posted Jun 30, 2016, 10:18 AM by Amir Borenstein, No Rad   [ updated Jun 30, 2016, 10:23 AM ]

Q - Hello I just order 3 of your electric magnetic radiation blocking fabrics (S240 & S238)
Thank you so much, I looked all over the internet for your product needed for electric emf's from using electric appliances I am going to make an apron to protect my upper and lower abdominal areas. Our house is full of emf and wiring issues. But the oven and refrigerator is killing me every time I cook on that terrible electric stove and get very high readings from my meters and also feel the sickness,
burning, pain and urination frequency. I am so thankful to you and your website.
I would purchase any cloths you have as well if they are mostly for electric emf's. We do live near clusters of cell towers too, but the RF's are very low. Please keep me as a life time customer.
Sincerely
J from USA

A - Hello J
Thanks for the worm words about my site.
Thanks for ordering from my site.
The Fabrics you ordered and most of our products are made to block RF-Radio Frequency Radiation. 
Most Electric appliances emit ELF-Extreme Low Frequency EMF radiation, which the fabrics will not block or reduce.
Some Electric appliances emit also RF radiation, but the right way to deal with this emission is to disable the wireless function or changing the appliance to a different model that does not have wireless capabilities and does not emit RF radiation.
We produce RF Protection Clothes and sell RF blocking fabrics but their main goal is to protect EHS-Electromagnetic Hyper Sensitive people (as I suspect you are) from RF that is not coming from their house, but from the out side, like for example cell towers.
The first thing you need to do is to disable or remove any wireless device from your house.
In addition please try and see if you have a "smart meter" installed against your wall, these emit high burst of RF radiation.
It will also help me to know which EMF meter you are using to measure the EMF in your house.
Please take a look at the following pages on my info site:
  1. Preview to EMF - http://www.norad4u.com/knowledge
  2. EHS - http://www.norad4u.com/ehs
  3. Exposure reduction - http://www.norad4u.com/emr-reduction
  4. EMF protection - http://www.norad4u.com/emr-protection
  5. Smart meters - http://www.norad4u.com/knowledge/smart-radiating-meters
After reading the above info, please let me know if you still want me to supply the order. 
I hope this info helps.
Thanks and best regards

Blocking RF from neighbor in a 'two under one roof' house

posted Mar 17, 2016, 2:33 AM by Amir Borenstein, No Rad   [ updated Mar 17, 2016, 2:39 AM ]

Q - Hello,

I have a question regarding the paint. I live in a `two under one roof´ house, is it possible to paint only the wall to my neighbour with the blocking paint to shield my family from the radiation? The guy has WiFi, a repeater and a dect phone in his house...

Best regards,
B.

A - Hello B.
It is possible to use RF protection on the wall between you and the neighbor in order to block most of the RF coming from his home, but it is important to pay attention to the  following:
1. If you use protection , you first need to make sure that you don't have RF emitting devices in your house.
2. Use an RF meter to make sure where from the RF is coming (some of it can also come from other places, directions or devices).
3. Find out what the ceiling is made of and if some of the RF generated by you neighbors is penetrating through it.
4. The right type of RF protection should be selected. For in house I prefer using the RF Blocking wallpaper - http://www.4ehsbyehs.com/rf-protection/rf-blocking-wall-paper
I hope this info helps.

I suffer from WIFI signals, would the RF Protection hats help?

posted Jan 14, 2016, 10:39 PM by Amir Borenstein, No Rad   [ updated Jan 14, 2016, 10:39 PM ]

Q - Dear Friends,
I suffer from WIFI signals from my apartment neighbors as well as pain if very close to cell phones.
I used a cell phone extensively for 20 years but cannot put one to my ear now without getting pain.
I was wondering if one of your hats RF (EMF) Protection Legionnaire Hat would stop the signals to my ears while sitting on my couch watching TV.  As well my ears get red and are hot when these signals are coming into our apartment.
Thanks for answering me.  I would like to order right away if you think it might help you.

Answer
Hello and thanks for contacting us at www.4EHSByEHS.com
EHS - It seems that you are an EHS person , like myself ( please see my info site - http://www.norad4u.com/ehs ).
Hats - Yes, Our line of RF Protection Hats should help you feel better when the RF radiation is coming from you neighbors, from cell towers, from WIFI routers and RF sources installed above you. 
I wear the RF protection hats all day long, including in the house and it helps me a lot.
Question - " flying at 35,000 feet," - commercial air plan or privet?
What more can you do?
In addition I recommend to get an EMF meter and start searching for RF/ELF sources inside the house, and penetration points where from RF and ELF are getting into your house.
RF sources that are found should be removed and changed to wired equipment.
ELF sources that are found should be kept at a safe distance from you, and unplugged form the electric socket when not in use.
RF/ELF penetration points should be blocked and protected.
Please see our info site for more info:
I hope this info helps.

P.S. -  you should not use cellphones or any wireless devices any more. 
Most EHS people report pain on every use.

Q - Hi Amir,
How do I differentiate between the shiny and non-shiny side of the screen?
J - Canada
29/11/2015

A - Hello
From past experience it is hard to notice a difference but the good news is that both ways the film works very nice.
If you want to do it 100% right, then the outside side of the film(the side that should be facing the screen) is the side which is covered by a transparent thin film layer. 
Try to take the 2 layers just a little bit apart in order to find the side which should be facing the screen.
One you find the outside side , make it face the screen.
I hope this info helps.
All the best
