Radio waves can be harmful to the human body. Because safe distances change by country and
ship construction, there is no standard formula to calculate safe distance. However, below are
general guidelines.
• FELCOM 500: Personnel should not approach an area in which the radiation level is higher than
10 W/m2, i.e., within 1.40 m from the radome surface.
Construct a protective fence around the antenna unit so that personnel can not approach the
antenna unit within 1.40 m. Also, to alert personnel not to approach the antenna unit, attach the
caution labels (supplied as installation materials) to any bulkhead which is at the position of 1.40
m from the antenna unit.
Do not approatch within 1.40 m of the
antenna radome when it is transmiting.
Microwave radiation can be harmful to
the human body, particularly the eyes.
