The Radiofrequencies

 

A very wide range of radiofrequencies, from 300Hz up to 300GHz, are invading our atmosphere. These waves are either analogue or digital:

 

- the analogue waves are emitted in frequency ranges lower than 300MHz and, according to the scientific literature, are not really damageable for the human being, if their density is not too high.

 

- the digital waves, emitted by cell phone antenna’s, cell phone, wireless DECT phones, WIFI,… have frequencies higher than 300 MHz. They are also called “microwaves ». These microwaves are pulsed at extremely low frequencies, between 4 and 217 Hz. The scientific literature is more controversial regarding their impact on the human health.

 

Experiences on fertilized chicken eggs have proven˛ that it is mainly these extremely low frequencies that disturb the living organisms. A cell phone in communication, placed above those eggs, leads to the mortality of a significant number of embryos.

 

Epidemiological studies have proven that people living in a radius of 300m around a cell phone antenna develop symptoms like sleep troubles, chronicle fatigue, blood circulation troubles, immunodeficiency, etc…

 

The following table present the biological phenomenons and the symptoms that scientific studies have observed and that are classified according to the emission density, expressed in µW/cm2 or V/m.

 

The American & European norms only consider the « thermal effect » provoked during an exposition of 30 min to the microwaves. But since more than 10 years, the « non thermal effects », that appear at frequency densities a lot lower, have also been studied and appear to be particularly damageable for people exposed to them day and night, like those living nearby cell phone antenna’s.

 

We recommend implementing the Salzburg norms, voted according to the precaution principle by this Austrian province:

- outside the house, the microwave density must be lower than 0.06V/m !

- inside the house, this density must be lower than 0.02 V/m !
