1 Watt into 30db gain results in about an RF power density 1m in front of
the feed element of 8W/m^2 Based on World Health
organization recommendations the safe levels are that of 0.4W/kg. So as
long as your mass is more 7lbs you should not have any adverse effects from
incidental body heating from time-limited exposure to being right in front
of the radiating element.
