Re: question about Vatican broadcasting

[Mauro Campoleoni <trentino@iol.it>]

Dear radsafers, and dear Ruth,



for what I know, I'm almost sure that here in Europe we use V/m for the 

electric field,

A/m for magnetic field and W/m2 for power density (...) at least here in Italy,

no strange units like inches or pints :-))



Jokes apart, we know that often the Press reports uncorrectly these units

preferring more usual words that can be closer to the reader's imagination.



Anyway, regarding the case of those Vatican antennas, we should consider 

the measurement as in the "plane wawe" case, so one can measure E (V/m) OR 

H (A/m)

OR P (W/m2), and E is much easier to measure. The limits in this case are:



       20 V/m for the electric field

       0.016 A/m for the magnetic field

       1 W/m2 for power density.



These limits are mathematically connected, so that they represent the same 

limit.

(For residential areas 6 V/m are recommended).



Friendly.
