question about Vatican broadcasting

[RuthWeiner@AOL.COM]

Perhaps some RADSAFER  -- especially perhaps a European one -- could answer a 

question that came up this morning in an article about the power of the 

Vatican radio and TV transmitter.  In the US, we measure RF transmitter power 

in watts, but according to this article, in Europe, this power is expressed 

in volts/meter.  Now, if I remember my elecricity and magnetism correctly, 1 

watt = 1 joule/sec = 1 volt-coulomb/sec = 1 volt-ampere.  So my question is: 

why "volts/meter", what are the "meters" referred to here, and how does this 

relate to watts?  Is this perhaps because all the European countries do not 

have the same voltage and/or current available (though I don't know why that 

would have anything to do with it)?


Thanks in advance
