I tend to forget how they work together, and then I rediscover that
the explanation given in the radiosity reference (3.3.4) regarding media
is rather terse ("Radiosity estimation can be affected by media" for
the media parameter).

There are different effects possible and it is not quite clear what
happens here. Can media get illuminated by radiosity? Does media reduce
the amount of light received by objects in the vicinity of an emitting
object? Does emissive media contribute light to radiosity calculations?
(the latter question is answered in the media documentation for
emission). Which effect is not possible, which is always
present, which is controlled by the parameter?

Media with photons and radiosity with normals are explained in
more detail in the tutorial section ( / that would
probably be a good place for some detail on radiosity + media
(with links from the radiosity and media reference?)
