Rad blast and procs

Assuming *only* Rad Blast, you probably end up with Neutrino/Xray/Neutrino/Cosmic, for a complete lack of other options. At very high recharge you can probably dump one activation of Neutrino, my perma-DrainPsyche Rad/Mental Blaster can run N/X/C seamless. (Although she's more likely to use Neutrino/Mind Probe/Cosmic) Putting a number to DPS would require you to post your build, and then there's math. Because it's going to depend too much on how much recharge you have an how well slotted your attacks are, and what kind of +Damage you're getting from IOs, pools, and your secondary.

Irradiate delivers all of its damage in 5 seconds, therefore it's not long enough to invoke the every-10-seconds proc chance for continuing powers. Any procs in Irradiate will activate only on the initial hit.

Actually, that doesn't even factor in. DoTs like this never proc per-tick, suppression or not.

There are ways powers can appear to have "ticks" of damage.

• A power that, on a given activation of the power (that hits the target), delivers its damage over time.
• A power like a toggle that attacks once every so many seconds. Blazing Aura is an example of powers like this

Procs are triggered only once per power activation. The first type of power above is only activated once, so the proc can only ever trigger once.

Toggles (and passives) re-activate on a timer, and since procs can go off once per power activation, they could theoretically trigger once per timed activation. However, since most toggles activate at very high rates (compared to click powers) the 10s suppression rule kicks in and prevents the procs from activating very rapidly.

"Patch" Powers like Rain of Fire, which we usually think of having lots of "ticks" of damage actually summon a critter who has a passive (auto) attack power that targets everything in the declared attack radius around the summoned critter. This is why these attacks honor the 10-second suppression - they actually represent a large number of independent attacks. Something like Irradiate, in comparison, is just a single attack.
