ADR TEX – dielectric screening of electric fields
1. What is ADR TEX?
ADR TEX is a low frequency electric field screen.
Our solution is based on an advanced dielectric composite, in which the electric component of electromagnetic radiation is absorbed by water dispersed in a dielectric matrix in various ways.
2. How does ADR TEX differ from other EMF screening materials?
Commonly used electric field shields such as Faraday cages, polymer or glass housed metal meshes, conducting polymers and soft materials made of cotton/polyester blended with micro-fine silver or stainless steel fibers are based on conductive media which need grounding. ADR MAT doesn’t contain any metal elements and doesn’t need to be grounded.
ADR TEX does not screen Earth’s natural electric field.
3. What is ADR TEX’s screening efficiency?
Screening efficiency depends on the amount of the substance applied into the matrix (density) and on the relative humidity (r.h.). The recommended humidity levels for inhabited indoor environments ranges from 40% to 70% (more information available at www.adr.com.pl)
4. Why is ADR TEX responsive to low r.h.?
ADR TEX responds to low r.h. because it contains water elements, which react with the humidity of the surrounding environment. When the humidity is similar to that of a desert or freezing weather conditions the water elements dispersed within ADR TEX are extracted. This reduction in screening efficiency is temporary and returns to normal when the humidity levels increase.
5. Is the ADR TEX still going to respond to low humidity if laminated with a vapor barrier instead of permeable membrane?
No, ADR TEX is not going to respond to low humidity if laminated with vapor barrier instead of permeable membrane.
6. Is the Tin foil screening efficiency dependant on the r.h?
No, the Tin foil screening efficiency is not dependant on r.h.
7. Why does ADR TEX use a permeable membrane when if a vapor barrier was used instead the screen would not be affected by r.h.?
Screens used in beds, mattresses and upholstery as well as in other applications should be breathable.
8. Wouldn’t it be more beneficial to use conductive materials to screen a human because ADR TEX is affected by r.h.?
All conductive screening materials need to be grounded.
When they are not grounded they start to work like an antenna sending random electric fields around.
When they are grounded through an electric socket for example, there is a risk that they will connect to stray currents and attract them towards the screen and therefore towards people.
When they are grounded through a water pipe there is a risk that the pipe might not be well grounded, or that the water installation is partially plastic.
9. Is perfect grounding possible at all?
Yes, perfect grounding is possible when we stand barefoot on grass, nearby trees and bushes are naturally grounded, and there are no other external interferences but the air that surrounds us.
10. Is it true that a conductive material used as a bed canopy is going to block out the Earth’s natural electric field, which is beneficial for humans?
Yes, a conductive material used as a bed canopy is going to block out the Earth’s natural electric field, which is beneficial for humans.
11. Is it true that ADR TEX used, as a bed canopy is going to let through the Earth’s natural electric field, which is beneficial for humans?
Yes, ADR TEX used as a bed canopy is going to let through the Earth’s natural electric field, which is beneficial for humans.
12. Is it true that conductive screening materials applied to walls weaken mobile phone signals?
Yes, it true that conductive screening materials applied to walls weaken mobile phone signals.
13. Is it true that a mobile phone located in a room where walls have been screened with conductive material is going to use a much greater intensity (energy) to look for the signal?
Yes, It is true that a mobile phone located in a room where walls have been screened with conductive material is going to use a much greater intensity (energy) to look for the signal? Therefore it will affect humans in a much stronger way.
14. Is it true that ADR TEX or ADR PRIMER applied to walls do not affect the mobile phone signal and other frequencies above 1MHz?
Yes, it is true that ADR TEX or ADR PRIMER applied on the walls do not affect the mobile phone signal and other frequencies above 1MHz?
15. Is it true that a mobile phone located in a room, which walls have been screened with ADR TEX or ADR PRIMER is not going to be affected?
Yes, ADR TEX and ADR PRIMER has no impact on frequencies above 1MHz.
16. Are there any ADR Technology screens that screen higher frequencies up to 3 GHz?
Yes, they have been developed for testing equipment and for devices used in medical diagnostics (NMR, MRI and EPR).
17. Is it possible to design an ADR TEX that can screen effectively in very low r.h. conditions (for example in a desert or in the winter where very low temperatures lowers the r.h.)?
Yes, it is possible to design an ADR TEX and ADR PRIMER that can screen effectively in very low r.h. conditions by adding more screening substance (higher density) and by modifying the hydrate. The latest developments have led to a satisfactory screening efficiency at even 20% r.h.
ADR TEX tests in r.h. 40%
18. Why does the meter show a different result when held by hand compared to when the meter is resting on the 50cm stand?
An accurate test can only be carried out when the meter is attached to a stand (the higher the stand the more accurate the reading). The reason for a different result when the meter was hand-held is because of the human body and the floor that the person is stood on. These are the influences of electrical potential and capacitance.
19. How can one be sure that ADR TEX works if a basic EMF reader is used and it shows confusing different readings each time?
Firstly one needs to make sure that the measuring device is switched on to the electric field component reading option (EF). Then the measuring device should be placed on a cable connected to a power source and the reading should be noted. This is the control measurement. Usually in Gigahertz readers the sensor is situated about 2cm down from the top of the device.
Secondly the ADR TEX should be placed on the top of the live cable and the reader should be placed in the same spot as in the first reading and the reading should be noted. The ADR TEX should be bigger than the measuring device so that the housing or casing is only in contact with the ADR screen.
Finally, the ADR TEX reading ought to be divided by the Control reading and the number given should be subtracted from 1. The total number given in% is the screening efficiency of ADR TEX.
Should the screening efficiency be much lower than 90% one should check the relative humidity conditions.
In order to make sure one’s measurements are correct, photographs of the two readings maybe taken and forwarded to ADR technology for consideration and feedback.
