Hmm... you're gonna have fun with this! POV-Ray doesn't really *scatter* 
light when it hits scattering media. That particular media just "shows 
up" when light hits it; the light itself is attenuated, but it sure 
isn't "scattered" in any meaningful way. AFAIK, not a way to simulate 
this accurately either...

POV-Ray is really designed for building nice-looking pictures. Is 
doesn't do "physically correct" quite so well... Still, maybe somebody 
else here can come up with something...?
