In fall 2008 the "Bund für Umwelt und Naturschutz Deutschland

e.V." (BUND) (environmental NGO) recommended a limiting value

of 1 µW/m² even for outdoor situations.

The Landessanitätsdirektion Salzburg (Austrian health authority)

proposed already in 2002 to lower the present ”Salzburger Vor-

sorgewert“ (precautionary value) to 1 µW/m² for indoor situa-

tions.

Limiting values imposed by governments are mostly considerably

higher. There are indications of rethinking, though. The Internet

provides large collections of recommendations and data.

Note for users of cellular phones: Even below 0.01 µW/m² com-

munication is fully unimpaired.

Identification of the sources of pollution

After determination of the total exposure the next step is to find

out where the radiation enters the examined room. As a first step

eliminate sources from within the same room (e.g. cordless

phones, wireless routers, etc.) Once this is completed, the re-

maining radiation will originate from outside. For remedial shield-

ing it is important to identify those areas of all walls (including

doors, windows and window frames!), of ceiling and floor, which

are penetrated by the radiation. To do this one should not

stand in

the centre of the room, measuring in all directions from there, but

monitor the permeable areas with the antenna (LogPer) directed

and positioned close to the wall/ceiling/floor

. The reason for this

is that the antenna lobe widens with increasing frequency. In addi-

tion reflections and cancellations inside rooms make it impossible

to locate the “leaks” accurately. See the illustrating sketch below!

For the definition and installation of shielding measures as well as

surveying their effect, professional advice is recommendable.

Anyway, the area covered by shielding material should be much

larger than the leak itself.

Audio Frequency Analysis (HF35C / HF38B only)

Many different frequencies within the frequency band between

800 MHz and 2.5 GHz, are being used by many different services.

Please note: In this position the readings on the LCD only indicate relative highs

and lows that cannot be interpreted in absolute terms.
