Guidelines, Limiting and
Precautionary Values
The official regulations in many countries specify limits far beyond
the recommendations of environmentally oriented doctors, "build-
ing biologists" and many scientific institutions and also those of
other countries. They are vehemently criticised, but they are none-
theless "official", and often the basis for authorization procedures.
The limit value is frequency-dependent and in the HF range of
interest here lies between 4 and 10 W/m² (1 W/m² = 1,000,000
µW/m²). It is based on an average value evaluation, which building
biologists consider far too low. The same point of criticism also
applies to the official limit values of other countries, as well as of
the ICNIRP (International Commission on Non-Ionizing Radiation
Protection) – the so-called non-thermal effects of EMF are ne-
glected. This is also "officially" described in a commentary pub-
lished by the Swiss Federal Office for Environment, Forest and
Landscape dated Dec. 23, 1999. These "official" limits are far be-
yond the range of this instrument, which is optimized for accurate
measurement of power densities targeted by the building biolo-
gists.
The building biology guideline SBM 2015 classifies the following
steps:

< 0,1
The "Bund fuer Umwelt und Naturschutz Deutschland e. V."
(BUND) proposes 100 µW/m² outside buildings. In view of the
shielding properties of normal building materials, far lower values
exist inside buildings.
In February 2002 the Medical Authority of the Federal State of
Salzburg, Austria, recommends to reduce its "Salzburger Precau-
tionary Recommendation" from 1,000 µW/m² to 1 µW/m² inside
buildings and 10 µW/m² outside. These limits are based on empir-
ical evidence over the past few years.
In summary it confirms the justification of precautionary limits
well below the present legal limits.
Users of mobile phones and Wifi please note: Even at signifi-
cantly lower power flux densities than the strict values recom-
mended by the SBM for pulsed radiation, i.e. at values of approx.
0.01 µW/m², you will always have excellent cell phone and wire-
less LAN reception.
