Guidelines, Limiting and
Precautionary Values
The official regulations in many countries specify limits far beyond the
recommendations of environmentally oriented doctors, "building bi-
ologists" and many scientific institutions, and also those of other
countries. They are vehemently criticised, but they are nonetheless
"official". The limit values vary depending on the frequencies looked
at, and in the HF range of interest here they are between 4 and 10
W/m², i.e. they exceed the recommendations by far more than 10 mil-
lion times (1 W/m² = 1,000,000 μW/m²). This point of criticism also
applies to the limit values of other countries as well as of the ICRNIP
(International Commission on Non-Ionizing Radiation Protection). Of-
ficial limits are determined by the potential heat generation in the hu-
man body and are therefore consequently measurements of averages
rather than peaks. This ignores the state of environmental medicine.
The "official" limits are far beyond the range of this instrument, which
is optimized for accurate measurement of power densities targeted
by the building biologists.
The building biology guideline SBM 2015, widely accepted world-
wide, classifies the following steps:

Anomaly
(μW/m²)
Critical radio waves, such as pulsed or periodic signals (mobile
phones, DECT, WLAN, digital radio, etc.) should be considered more
damageable, especially when frequently measured, whereas less
critical radio waves, such as unpulsed or non-periodic signals (VHF,
short wave, MW, LW, analogue radio, etc.) can be considered less
important, especially when less frequently measured.
The "Bund fuer Umwelt und Naturschutz Deutschland e. V." (BUND)
proposes a limit value of 100 μW/m² for the outside of buildings. In
view of the shielding properties of normal building materials, the val-
ues inside buildings should be far lower. In February of 2002, the
Medical Authority of the Federal State of Salzburg, Austria, recom-
mended to reduce its "Salzburger Precautionary Recommendation"
from 1,000 μW/m² to 1 μW/m² inside buildings and max. 10 μW/m²
outside. These limits are based on empirical evidence over the past
few years.
In summary it confirms the justification of precautionary limits
well below the present legal limits.
Note for users of cellular phones or Wifi:
Unimpaired reception of calls or Wifi is possible with power densities
far below even the very strict precautionary recommendation of 0.01
μW/m² for pulsed HF frequencies by the SBM.
