Radiation hazard sign warning people not to open the container. The windmill-shaped symbol (upper left) is the internationally-recognised radiation hazard sign. It usually warns of radioactive materials such as uranium and plutonium, or the radioisotopes used in nuclear medicine. All these materials emit highly energetic radiations that are dangerous because they can cause massive damage to body cells and their genetic material.
