Re: Military Ship Radar

Randy et al.,

The US Navy has a standing order that no EM/RF producing
equipment is to be energized "...when personnel are
working aloft".  The majority of non-ionizing radiation
is generated by antennas relatively high on the super-
structures of military and civil ships.

Power levels fall off rapidly near docks or even lower
decks (assuming a system should happen to be energized 
while in port, and that the near-field/in-field 
effects are the most important for bioeffects with the 
far/fringe fields significantly less important).  Also, 
many of these systems are highly directional (for 
example, targeting areas at or above the horizon line).

The US Navy Environmental Health Center (NEHC) may be
able to provide more detailed info/reports, a great many
have been done [sorry I don't have any email addresses 
for them].

This information is disclaimed as unofficial (that is,
unreviewed by any agency or employer) as usual.
