Try increasing the samples a little if you get "static". If you just get 
a smooth color, try decreasing the density of the media. To do that, 
just give it a darker color, I usually use a multiplier value for this:

emission color Yellow*0.1
or
absorption color rgb <0.004044, 0.714855, 0.004044>*0.05
or
scattering {1, rgb Green*0.5 extinction 1}

Also try lowering the extinction value in scattering media.
