>I have no physics education, I'm using common sense. That's a mistake. "Common sense", or the mental picture of "how things work" you've built up over a lifetime is utterly useless when it comes to nuclear devices. Things that common sense will tell you are super dangerous really aren't, and conversely things that common sense tells you should be safe are not at all safe.
