Men at work with machinery in an automotive factory. A doctor adjusts a dial on a machine in a cubicle with a patient. Archeologists at work on an archeological dig. A man passes a sign reading ‘ Warning Lethal source in use do not approach without a survey meter.’ He walks down a sandy lane with others. A rod among crops becomes animated and begins radiating atoms. A recreation of Henri Becquerel in his laboratory. He holds uranium on a photographic plate wrapped in black paper.
