If you want to do radiosity in animations, make sure to use very
high-quality settings to minimize any radiosity artifacts (which of
course requires high render times, which you'll usually want to avoid in
animations).
If your animation is limited to changes in camera perspective you can
mitigate this drawback by re-using the radiosity samples from frame to
frame. You may even get away with lower quality settings if you do two
passes of the animation, one for collecting radiosity samples to cover
all camera angles (this can be a low-resolution pass rendering only
every N-th frame) and one for the actual render. (Without the first pass
you might see some flickering at the border of areas the camera sees for
the first time).
