Radioactive Sign

The "☢" emote or "Radioactive Sign" emote is a symbol used to indicate the presence of radioactive material or radiation. It was first created in 1946 and has since been widely recognized as a warning symbol for hazardous materials. The three blades of the symbol represent radiation emanating from a central point, while the circle around it represents containment or isolation. The symbol is commonly used in scientific and industrial settings, as well as in popular culture as a warning of danger.
