The radiation would be nuclear after nuclear bombs made the surface uninhabitable. This is going to be set in the future so I don't need it be super exact, just believable. As for #2 if the whole earth's surface is irradiated can you send a signal or 'call' a space station orbiting the earth, the moon, or even Mars? Again, it's science fiction so there has to be some fiction. #3 I don't know much about what it would take to power a spaceship, as far as I'm concerned I don't care what it is as long as it will believably power a spaceship. My characters have to build it in a underground facility, and then use the ship to leave earth without blowing up. I'm not good at science, I just saw all the comments on the TV show 100 about how none of the science worked.All of it sounded fine to me but like I said I'm not so good with science. I just want my book to make sense and be believable.
The main character is an AI, obviously humans can't go out into radiation but I need my AI to be able to. She doesn't have to live in the radiation just go out in it. I don't know, maybe this story won't work. Maybe I'll have to come up with a different environment for my story.
