Radioactive emoji meaning

The radioactive emoji is an image of a bold black and yellow symbol that looks like a three-bladed fan inside a circle. This design is widely recognized as a warning sign for radioactivity, a highly dangerous form of energy that can be harmful to living things. Its striking design is meant to grab attention and convey caution or the presence of something hazardous. While its primary meaning is related to science and danger, people often use it more creatively in conversations. For instance, it can represent a risky or toxic situation, or even be used humorously in casual chats to exaggerate drama or playfully warn someone.

The radioactive emoji was approved in Unicode 1.1 and added in Emoji 1.0, see related proposal L2/13207
