Extremely high growth rates in mobile communications have led to several hundred million mobile phone owners throughout Europe since the 1990s. The impact of this "flood on the sky" on human health is still a hot topic.
Scientists from neutral research institutes have found that there are no longer any effects of low-frequency pulsed high-frequency signals on biological processes and on the nervous system in their studies.
As part of an investigation of the Thoma Research Center in Goldegg more than 100 different building materials and their combinations were tested at the University of the Federal Armed Forces in Munich for their attenuation for technically generated, high-frequency waves. During the measurement it was examined how much of the emitted power penetrates the test specimen.
The result provided the best values for thick wooden walls!
Contrary to all expectations, the building material wood - tested in the form of non-glued, fully solid Thoma Holz100 walls - shields considerably better than, for example, brick variants or lightweight construction systems.
Here are the damping values of a 17.6 cm thick Thoma Holz100 wall:
- At 900 MHz (D-Net), only 25% penetrate through the wooden wall
- At 1800 MHz (E-net), 10% penetrate through the wooden wall
- At 4 GHz, only 1% penetrate through the wooden wall
- Starting at 6.5 GHz, less than 1 per thousand already penetrate through the wooden wall
