WHAT WE HAVE FOUND?

Regarding Electromagnetic waves in the sleeping room, the reading is very high: 13.000 μW/m².

Regarding Altern electric fields (low frequencies) we have checked the grounding having readings of 1-2 Ω. The electric fields have not been checked.

 

WHAT SHOULD BE FOUND

Electromagnetic waves: readings should be under 10 μW/m2 and ideally under 0,1 μW/m².

The grounding reading should be under 6 Ω.

 

WHAT ARE WE GOING TO DO

For the electromagnetic waves a shielding will be made in the façade facing the source (mobile antennas)

The electric wiring will be completed by adding grounding wires in all the lines which miss it. This should be enough to have sufficiently low altern electric fields readings.

 

RESULT AFTER THE INTERVENTION

The readings for the electromagnetic waves in the sleeping room are 420 μW/m² out of which 45 μW/m² are pulsed waves. The source of these pulsed waves falls in the DECT frequency channel. Two land line cordless phones from two different neighbors are the cause of such pulsed waves.
