Sound search - Choking Cloud (rad) and others

[Guu]

I've come across a few sounds that I just want to be silent or replaced with other, less annoying sounds. I've been mostly successful, but I simply cannot seem to find the entry for "Choking Cloud" in the Radiation set. Could someone direct me to it, please, or (even better) a list of where all the sounds are located? This sound has a low rumble to it that really grates on me. I've exhausted everything I could find in data\sound\Ogg\Powers, including the radiationX_loops, where X is a number 2-5 or so.

Thanks!

No one knows? Hmm. Guess I'll keep looking.
