That's exactly what we were thinking too. The mix ratio is 100:1, so 1%. Not
a whole lot so it shouldn't change the "optical" properties much at all but
it should add scintillation.
We didn't think about the simulation being slow... I'm just about done
writing the random number distribution though so we will try it and see how
it goes.

That&#39;s exactly what we were thinking too. The mix ratio is 100:1, so 1%=
