Thanks for responding.
Since I don't know bob's very well (I tend to go more for small mods), I didn't try to make it compatible, particularly as I was worried about name-spacing issues, as if I use the same internal name for something as bob's, they just won't be compatible. Out of curiosity, does the mod load with bob's, or if not, what error do you get? Also, do you know if bob's mods change the base atomic-bomb recipe, as I can't seem to find it if it does...
I wouldn't use u-234 in any weapons (it isn't used for them in real life), but will have a look at adding alternative recipes using plutonium.
Beyond that, I will have a look at a dirty bomb, I take it you mean something like the poison capsule, but with radiation, as that wouldn't be hard at all, and I will have a look at sorting something out.
Thanks for the ideas, and hope you enjoy the mod.
