The best detail: when some of the sealed containers wouldn't sink, the AEC workers shot at the containers from the boat... so that they would sink. You and I can't get jobs that stupid; we are under-qualified.
The radiation presents the sci-fi premise of radioactive Great White Farallon Sharks. Of course, in my limited realm of imagination, the pernicious effects of radiation don't result in more savage Great White Sharks, but rather, "cuter, fluffier" sharks as I have watercolored above. Lamentably, the action comic seems ever beyond my feminine grasp. At this point in life, I might just learn to live with it.
