If you were designing a sign that people might refer to in times of national emergency would you try and make it as calming as possible? Or would you try and render – in a graphical format – sheer panic, and er, impending death from above? Yeah, me, and the International Atomic Energy Agency too. 

Actually, the “new symbol is being launched by the IAEA and the International Organization for Standardization (ISO) to help reduce needless deaths and serious injuries from accidental exposure to large radioactive sources”, or if you prefer, to warn everyone that they should run as far as possible from the curly arrow spitting space ship and its ground-based skull infantry. 

Either way, I’m just going to hide under my desk until it passes.
