ELF Magnetic and RF protection in a Car

posted Apr 22, 2018, 3:49 AM by Amir Borenstein, No Rad

Question: 

I am very EHS sensitive. I need to know which cloth to buy if I want to line the entire inside of my car because the magnetic fields everywhere in the car are extremely high, even with us removing many of the fuses from the electrical devices. 

Can your shielding fabric stop the magnetic field within the car as I am supposed to be at lower than 20 nT. 

I know I can't return the fabric so I want to make sure that if I line the car with this fabric it will stop the magnetic field. I have no problem with electric field in the car.

Also I would need to know what I could install over the windows to stop the radio waves and magnetic fields from entering in through the window. 

I would like to place order as soon as possible.

thank you
M - USA


Answer:


I am sorry to hear about your condition.
I am also an EHS person.
Regarding ELF magnetic field protection in the car, it is almost impossible. 
This is because ELF-M tends to bypass protection from the side and holes in it. 
In addition putting a hard non flexible ELF protection in the ca can be very dangerous in case of an accident.
This is way I recommend not to protect from ELF in the car.
I do recommend to test the car before buying and getting a low ELF and RF car using a home use EMF meter like the CORNET ED88TPLUS - http://www.4ehsbyehs.com/emr-meters/cornet-ed88Tplus
I do recommend removing/turning off any RF emitting devices from the car and then use RF protection films on the side and  back windows.
Out shielding fabrics blocks RF not ELF.
I hope this info helps
Thanks and best regards

I am hoping to get someone to take some readings in my apartment

posted Feb 10, 2018, 1:28 AM by Amir Borenstein, No Rad   [ updated Feb 10, 2018, 1:29 AM ]

Q - I have had increasing problems with my apartment in San Francisco. 
Radio antennas, T-mobile , MUNI , tranformers, AT&T towers....
I gave up having a tv and even a landline. All my electronics seem to be effected. 
My health is suffering.. sore throat, pressure in eyes, buzzing in elbows, bone loss, digestive trouble, headache, tinnitus... 
Symptoms go away if I leave town. I wake up each morning with a headache, jaw clenched, fist clenched, extreme pressure in my eyes, constant white noise.

I am hoping to get someone to take some readings in my apartment and make some recommendations as to what I might be able to do to protect further health problems from the conflagulatin of dirty electric in my apartment location.
I would appreciate any suggestions.
Thanks for your time

A - Hello
I am located in Israel.
What I can recommend to you is to get an EMF meter and do the measuring yourself. It would be hard finding professional EMF testers that understand the possible health risk from day to day exposure to low level EMF radiation. I recommend to learn, measure, reduce and protect.

The first thing you need to do (which I guess you already did) is remove any wireless devices from the house and stop the use of cellphones.
The second thing is to get an EMF meter, both for RF and ELF and to start measuring the house.
Find sources in the house, remove any RF emitting devices, keep safety distance from ELF emitting devices.
Then use the meter to find RF penetration point into the house.
Then use RF protection to block the RF from entering the house.
Another thing I would do right away is to find out which electric and gas metters you have and where they are installed.
If you have a smart RF radiating meter on your house I would try to not stay or sleep near it , try to use RF protection against it (to block the RFR from coming into the house) and would try to option out.

What is the possible EMF from an adjustable electric motion bed

posted Jan 10, 2018, 1:52 AM by Amir Borenstein, No Rad

Questions - Please can you tell me about the possible EMF from an adjustable electric motion bed? I cannot seem to find anything , CANADA 10/01/2018

Answer - I don't recommend the use of electric beds, mattresses and beds with metal parts in it.

Hello
Electric bed usually have a power converter, a small electric engine and an electronic control unit.
All emit ELF magnetic fields.
The power converter usually emit the ELF magnetic field all the time it is connected to the power netwrok.
So the ELF fields on the bed are there night and day.
In order to remove the ELF fields you need to unplug the bed from the electricity network.
In measurements I did I saw ELF magnetic fields of up to 40mG on the mattress.
In general I recommend not to use an electric bed at all. 
I also recommend no to use electric blanket when slipping (before is OK as long as you unplug it when laying on it)
I also recommend to use a bed that have no metal parts (or as less as possible) and a metraiss without metal springs in it, since most metal wires and long parts become passive Radio Frequency(RF) antenna when around RF radiation.
Please see my site for videos and explanations:
I hope this info helps.

Good WIFI and Bad WIFI

posted Nov 20, 2017, 11:50 PM by Amir Borenstein, No Rad   [ updated Jan 10, 2018, 1:40 AM ]

Q - Hi Amir,
Hope you are doing fantastically well.
Just wanted to say thank you for all your help.
The Gabba is really helping me and so are the emf cloths i have been using while traveling.
I have one quick question for you...
The last three places I lived had wifi and it didn't bother me.
Currently, where I'm at.. It really does.
Is there a bandwidth/setting that is less powerful than others .... And that could be the reason why?
I don't have the option of going wired....
I truly appreciate your help.
Best,

L. ;)
USA 21/11/2017)

A - Hello L.
In order to understand why you react to one house with WIFI and not to another house with WIFI, you need to try and understand what systems are deployed and installed in these houses.
For example, there are WIFI routers with only 2.4GHz band, and others with both 2.4 and 5GHz bands.
For example, there are WIFI routers with external antennas that have more "strength" and routers with internal antennas.
It is possible that in one house there are "WIFI extenders" deployed, and an other house with only one router.
It is possible that in one house you have a WIFI device next to you and in another house the closest WIFI device is far a way.
Use your RF meter to search the house for WIFI devices and other wireless/cellular devices in order to tray and understand why you react in one house and not in the other.
In addition, going wired should be your primary priority. 
If you have not choice but to use WIFI, try to use an external WIFI network card with an 5-10 meter powered USB cable, and more the device away from you
Like this:

Good and bad grounding

posted Mar 10, 2017, 1:51 PM by Amir Borenstein, No Rad   [ updated Apr 27, 2018, 11:28 PM ]

Question - How to create a good grounding system for all my protection? 
Is it OK to use the electric ground?

Answer - I recommend not to use the electric ground on the electric socket, but to a special pole outside.
It usually have some micro currents on it. If you connect your grounding to it, the currents might end up on your protection. If you touch it, the currents might find their way onto your skin and nerves system. 

Lots of people think about grounding as a ON/OFF 1-0 thing, you either ground or not. While from my experience it is really a very complicated issue. The Electric ground usually have some small currents and low voltage on it (noise) and in some cases even the a pole in the earth backyard will have some stray currents. This is way I always try to figure out if the ground is good or not. 
A bad grounding will not only cause problems while grounding ELF/RF protection to it, or when connecting grounding mats, it might even pose a real problem just for living in that house. I must say that I haven't created the grounding thin yet, I just have best practice:

I recommend to use a grounding pole and insert it to the real ground on your back yard.
If possible make sure the dirt there is always wet. Then connect your grounding mats and protection to this pole. Make sure you follow the following Best practices.


Best practice for creating a good grounding:
1. Make the grounding cords as short as possible.
2. Have as less as possible connections points between the protection to the pole.
3. Make sure the connections are as strong as possible (lots of contact).
4. The impedance should be as low as possible (lower then 1 Ohm is recommended).
5. Ground all connection to a grounding pole on the yard.
6. Don't connect to the house electric ground.


How to test your grounding quality:
1. Test for electric current (only if you know how) or ELF Magnetic field around ground wires and water pipes, if you see a field there, there is some ground current, and the grounding is bad.
2. In case that an ELF electric field meter shows higher levels when you extend your arm to grab it (when you are grounded or not), there is either a grounding issue in the electric system, or some source of field around you.
3. If you touch the taps or water pipes, or the grounding, and feel some electric shock, usually when walking barefoot, in most cases there is some grounding issue.
4. Test the grounding for noises using a scope. Make sure it is clean. test between the ground and the neutral, between 2 poles in the ground 2 meters apart, between the ground and the water pipes.

Smartwatch makes me feel bad

posted Jan 28, 2017, 2:33 PM by Amir Borenstein, No Rad

Q - Hello - I brought a 3G enabled smartwatch which I could place my phones SIM card inside. It was an Android 4.0 smartwatch. Within 1 day I felt a heat through my wrist - even thought the watch was cold and with the screen off most of the time. By day 2 I had to take it off as I felt as if I had sunburn right through my wrist and it took 3 days for the discomfort to go. I made a disk 6 layers thick of tin foil and put that under the watch and wore it again and it was fine. Has anyone attempted to measure the radio frequency radiation of these 3G enabled smartwatches comiing out of China? Do you sell any shielding for smartwatches? Many thanks.


A - Hello
My recommendation is to stop using the watch.
smart watch, with or without 3G inside , emit RF radiation. 
There is no shielding for that, just stop using it.
Please see:

Which cell phone do you use, and what is SAR?

posted Jan 13, 2017, 8:58 AM by Amir Borenstein, No Rad   [ updated Jan 13, 2017, 9:07 AM ]

Q- Which cell phone do you use, and what is SAR?

AHello
1. I don't use a cellphone on a daily basis. I do have an old 3G (UMTS/WCDMA) phone for emergencies which I use once or twice a month (with air tube earpiece) and a car phone with the antenna on the external side of the wind shield.
The reason is that every cellphone, even "low" SAR phones, emits RF and ELF levels that are too much for me and cause me pain after few seconds.
2. SAR is a measurement Technics that servers the need of the wireless industries to show as if the phones are tested and found to be safe. In reality it is based only on thermal damage and is not relevant to any biological damage what so ever. 
3. a phone with low SAR level, with not necessary radiates less then a phone with high SAR level
4. There are other parameters that effect the levels of emission from each phone in each and every situation, such as: reception, setting of the phone, way of using it, technical parameters and other variables.

Are CRT worse than LCD or LED?

posted Oct 15, 2016, 11:06 AM by Amir Borenstein, No Rad   [ updated Oct 15, 2016, 11:56 AM ]

Q - Hi "NoRad"

I'm interested in your view of CRT TV sets. Is the radiation from those, compare to a LCD display, worse?

I've read of people that don´t feel bad from CRT but do feel from LCD, even though the CRT naturally uses higher power.

Do you have any experience in this?

Thanks


A - Hello

Yes, CRT have much more ELF magnetic and electric fields than LCD display.
In addition you can even find LCD/LED displays with external power supply, making the ELF emission even lower.
Some people might be OK with CRT (from some distance) but feel bad from LCD or LED display because of one of the following reasons:
1. Blue light emitted from the screen (fix - change the color scheme so there will be less blue light).
2. Mid frequency EMF emitted from the screen (fix - use a LCD/LED screen protection).
3. RF radiation emitted from the screen in case it is wireless (fix - test before buy, make sure your screen is not wireless, or find a way to turn off the wireless functions).
4. Dirty Electricity created by the screen (fix - use DR filters) 
5. Light flicker (fix set brightness to 100% in LED screen)
I hope this cover all.
All the best
