Hi.
Maybe Im not the best one to give advice because Im a real /Rad fan(40 fire/rad, 40 ice/rad)...and i would choose everyone 
Well,not really,fallout and ckocking cloud are useless,radiant aura and EMP are a-must(big part of the Rad PVP success) and I think the best advice is:"Dont doubt it! slot LR for slow(it REALLY matters)"
Yup good advice from Tchalla 
EMP is very situational though. In my opinion of course! I do have it myself, as I wouldn't feel like a rad without it
I put 6 slots in Rad inf, AM and Lingering Rad.
This is how I have mine slotted.
Rad Infection - 3 acc debuffs, 2 def debuffs and 1 end reduction.
AM - Pretty simple, 3 recharge and 3 endurance mod.
Lingering Rad - 3 slows, 2 acc and 1 recharge.
Enervating field - 2 end reductions (wish I had another slot for that one).
I love mutation as well. Just remember to tell your team to take a sec to rethink hitting the hosp button when teamed with you. Also once i7 hits I believe Rezzes will be loved by many due to having to start out with 1hp 1end everytime you go to the hosp. Maybe people will start to think twice before clicking the hosp button. Well I can hope can't i?
You people saying you need to put slows in LR are nuts. That power has a really silly long recharge, so it needs 2 acc (or 3), 3 recharge redux. It's a very powerful slow right out of the box, it doesn't need extra but if you find you have spare slots it can't hurt to put a slow in.

Thing is: hasten + AM is 70% time up both(perfect for PVP)
That put LR on 2 Acc,2 Rech,2 Slow with a recharge of 35 and a duration of 30...wich means you almost stop him with 5 sc pause.
I prefer this slotting to 2 Acc,3 Rech,1 Slow wich is perma LR on target(1 sc down) but i guess is a matter of taste.
Never said you have to 
and maybe 3 rech is better. I really haven't done that much testing with it. Definately worth trying out, thanks

Irradiator is right, and in fact, the slow enhancement only affects movement speed (not recharge or regen), so not really worth using more than 1 slow imho.

Hi y'all
I have a rad/rad at level 21 who I plan on speccing for PvP. Anyone out there know enough about these powersets to suggest which powers I'd be mad to miss out, and which powers I can skip? I would assume that the powers to take would be Accelerate Metabolism, RI and EF, LR from the secondary, and NB, Cosmic burst, the nuke and irradiate from the primary.
