Abstract


The
monIT

Project provides public information on population exposure to
electromagnetic fields (EMFs) from mobile communication systems in Portugal. T
he
monitoring system is based on a network of autonomous remote probing stations, and
also on an extensive EMFs sounding program, both carried out in public areas across
the country. Measured results are automatically uploaded to a website for public
disse
mination (
www.lx.it.pt/monit
), which includes also other relevant information
about EMFs for the general public. This paper describes the project structure, the
automatic monitoring system, the project activities,

and finally it presents a brief
analysis of the measured results.

Results from the 311 measurements carried out within the EMFs sounding program
show that radiation levels in all the analysed sites are below safety levels, with 62 % of
the measured points

being at least 32 times below the EMF radiation strictest threshold.
Another interesting result is that the distribution of all measured points is almost
independent from the distance to the antennas, meaning that for each distance there are
higher and lo
wer field values. This way, one can conclude that in real urban
environments the distance to the antenna is almost irrelevant to evaluate the risks of
exposure to the radiation.
