Time for fun with radiation?

[Defenestar]

So I'm doing an Armagordon run, and I look at the Death Arc and Ignition Zone powers and something occurs to me about what radiation tends to hit.

Radiation hits dense things more, 'coz there's more to hit (not news to anyone, I know). In military vehicles, the really dense stuff hangs out in the munitions. Depleted uranium, tungsten, even just boring old lead. And that's right up next to explosives.

I guess what I'm thinking is that some of these radiation-based weapons could maybe use a chance to start cataclysmic internal fires in vehicles that are currently kind of resistant to them.
