WHAT HAVE WE FOUND?

Regarding the altern electric fields measured with the free potential method the readings were strong: 9 V/m in a bedroom.

Regarding the altern magnetic fields the readings were extremely significant: 280 nT in a bedroom due to the proximity of the apartment’s boiler itself.

Regarding the electromagnetic waves, the readings were strong: 150 in a bedroom mainly due to the neighbour’s cordless telephone.

Regarding the continuous electric fields the readings were extreme: -3500 V in a bedroom due to a teddy on the bed.

Regarding the continuous magnetic fields the readings were extreme: 19 µT in a bedroom due to the mattresses with steel materials (buffers).

Regarding the radioactivity the readings were insignificant: 0,39 in a bedroom.

 

WHAT SHOULD BE FOUND

Altern electric fields: readings should be below 1,5 V/m and ideally below 0,3 V/m.

Altern magnetic fields: readings should be below 100 nT and ideally below 20 nT.

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

Continuous electric fields: readings should be below 500 V and ideally below 100 V

Continuous magnetic fields: readings should be below a difference of 2 µT and ideally below 1 µT.

Radioactivity: readings should be below a difference from the background reading of 70% and ideally below 50%.

 

RECOMMENDED ACTIONS

Altern electric fields: shielding a neighbour’s walls

Altern magnetic fields: move bed away from the kitchen’s wall.

Electromagnetic waves: Shielding the bedrooms

Continuous electric fields: Moving the teddy away from the bed or putting on clothes to it in an electrostatic free material.

Continuous magnetic fields: replacing the mattresses with iron free ones.
