I don't know where else to ask this, but I have seem similar questions on this part of Stack Exchange. Basically, this is a serious curiosity. In other words: I want to know what would happen to everything that was once living after a cobalt bomb was detonated somewhere? I mean serious in the sense that I'm not interested in "building a world" for some kind of fiction. I'm just really curious.
Because of the intense radiation I have a few assumptions, but I know very little about them. Basically, assuming something survives the blast without being vaporized, but dies eventually (eventually being within the next day or so) what would happen to it after it has died? Would the body decompose? The concept of a cobalt bomb is to produce short but extremely intense radiation, so much so that almost nothing would survive it. My assumption regarding this scenario is: the body would literally be preserved by the radiation. I don't know if the organisms which ordinarily decompose once living things could survive themselves. I don't know if the microbes which do the same would survive either.
I guess my real question is: would the radiation produced by a cobalt bomb preserve everything which has died?
