The discussion on the disposal of ethidium bromide echoed in my mind
the other afternoon as I was cutting out of the building.  Walking
down one hallway, I passed a room where the lights were turned off
and where a graduate student was standing over a UV box, gowned,
gloved and wearing protective eyegear while standing over her gel 
on the UV box.  What gave me pause was that the UV light box was on
a table right beside the door, where everybody walking past was 
bound to peer in.  Granted, the passersby get a brief exposure to the
UV, and the strength of the light attenuates quickly with distance,
but I was curious to know what the rest of you think about this.
How dangerous is it to have your light source briefly being exposed
to the naked eyes of passersby?
