The project objective is to develop an information system,
mapping and risk analysis tools for the domain of the
ubiquitous NIR (non-ionizing radition), or electromagnetic smog.
While the possible health and environmental impacts
of non-ionizing electromagnetic radiation are still
controversial, a first step to put the often heated
discussion on a more rational basis is to compile
all available data on the physical side, that is the actual radiation
fields due to a variety of sources such a high-tension power lines and
various antenna, from TV to mobile phones.
Maintaining a data base of sources is the first step to model
their behaviour, and map the results vis a vis primarily the
population distribution. This can also be compared with actual
field measurements to calibrate the models. Measured and computed
radiation fields can then be used to estimate levels of
The system features a number of fullt integrated elements,
data bases, and analytical tools:
- basic environmental information system and GIS
for the regional background information including topography, landuse,
building structures, and population distribution;
- a comprehensive data base or inventory of all
major soucres, including:
- high-voltage power transmission lines;
- radio and TV antenna;
- cellular telephony antenna.
- a set of models to estimate the electromagnetic field
from each of these sources, based on their characteristics
from the inventory;
- tools for the analysis, display, and mapping of these fields,
including interactive 3D visualisation;
- tools for exposure and risk analysis.
