Good advice, but let me just throw in a comment.  Police radar guns
are continuous-duty devices (well, CW, sometimes switched off, but
not in a pulse fashion).  The highest power one I know if is 8 watts
ERP.  Most are between 800 mW and 4 watts ERP.  This isn't really
high power, however, there was a study done and the cancer rate
of police officers who had been using radar for a number of years
was on the order of 3 times higher than those who didn't.  Don't 
remember who did the actual study, but it was published by APCO a
few years ago.
