The notion that nuclear energy is 'unnatural' is farthest from the truth. We are constantly surrounded by nuclear processes emitting radiation, albiet in low quantities. The trouble starts when we concentrate and enhance nuclear effects. Sometimes this has healing uses, such as in the medical field. Other times, extreme devistation can result. Except for mans use of fire, there has not been a more potent source for good or evil than nuclear energy. It's a very wicked genie we let out of that bottle!
