Hi Thierry

I dont have the answers on hand. There are however exposure limits set
by legislation in various countries. You will often find websites that
help you determining what the conditions are at your location. Amateur
radio stations for example meed to be concerned about EMR levels when
the radiated power gets high.

If you cant find anything on your countries radiocomm authorities site
have a look at the US's FCC or Australia's ACMA sites. The exposure
limits tend to be a fairly universal thing. I would suggest too that to
license such a radar structure a EMR study would have to be done as a
matter of course. This is a important part of spectrum and safety
planning that is certainly the norm in Australia.

I would suspect too that being used for ships at short range the output
power would not be nowhere near what is used at longer distances. If
perchance it is used for longer range as well, then the antenna system
would be designed in such a way that most of the radiated power is
horizontal and as such only a small component would be aimed down at
your office/work location. This is the same logic as placing a cellphone
antenna up very high so that nearby EMR is not an issue.

My gut feel is that it is safe. You havent of course provided power and
antenna pattern figures for the installation.

Is it safe to work in that area????
