It seems that: radiosity + photons - media = no artifacts.

I used more detailed radiosity settings and turned normal to off.:

global_settings {
  assumed_gamma 1.0
  #if (RadiosityOk = on)
    radiosity {
      pretrace_start 0.1
      pretrace_end   0.0025
      count 500
      error_bound 0.5
      nearest_count 8
      recursion_limit 1
      brightness .8
      normal off
    }
  #end
  #if (Photons)      // global photon block
    photons {
      spacing 0.03   // specify the density of photons
    }

  #end
}

Does this mean that media needs more precise settings in conjunction with 
the photons?
