I'd change the slotting a bit to get 3 damage enhancements in each attack power, 3 end reduction in enervating field and maybe get rid of the end red in em-pulse.
Lingering radiation is much more useful than choking cloud in my eyes, I'd get that instead. If you still want choking cloud (which is of limited use if not slotted heavily) get rid of mutation as that is a pretty situational power which can often be replaced by an awaken.
ok thx, i'll try that 
Well, i made a corruptor and rolled Rad/Rad an I really have very little clue on how to build it, so i looked up on some of the posts and it got to this..
I'd like to have some comments on this build..
