Actually, the range is somewhat more. The Gundam's beam rifle is
supposed to have an effective range of 10 to 20 kilometers in open space;
the upper limit is the F90-IIL's huge rifle, with a hundred-kilometer
range. Atmospheric scattering would limit this range somewhat, but in
episode 9 of 08th MS Team, Sanders is still able to hit a Zaku from a
ten-kilometer range (with, admittedly, extreme dificulty).
The apparent lack of side-effects from intra-colony beam fire may be
due to the relatively small holes created by beam weapons. It would take
days for all a colony's air to drain out of even a large hole, let alone
a beam weapon blast. The real danger in using beam weapons inside a
colony is that they can trigger mobile suit reactor explosions, which
create _much_ larger colony wall breaches.

The sensor radius would presumably depend on the size of the target;
I'm sure Gato is firing from a lot further than ten kilometers away when
he nails the Birmingham with the GP02A's nuke. I'd assume that the listed
sensor radius is with respect to a mobile suit-sized target.

The VSBR can be set to either a low-speed mode that spreads out the
damage over a large area, or a high-speed mode for better penetration.
The latter mode, which is used to pierce enemy beam shields, would create
only teensy and easily fixable breaches; the former would be more
dangerous, but still nothing compared to the damage caused by a reactor
hit under any circumstances. Essentially, mobile suits shouldn't be
fighting inside colonies - or if they must, they should use missile and
projectile weapons as the Crossbone Vanguard do.
