radioactive Emoji

The radioactive emoji is a symbolic or functional icon — used for signaling, labeling, warnings, or abstract concepts (like direction, currency, or math) rather than depicting a literal object, person, or place.

Category context: The Symbols category gathers abstract icons — arrows, math notation, currency, warning signs, and keycap numbers — that function similarly to the Miscellaneous Symbols and Dingbats Unicode blocks, but rendered in full emoji color style rather than plain text glyphs.

Cataloged under Warning within the Symbols category, radioactive is the 208th of 224 emoji How To Type Any Symbol lists in this category, and was introduced in Emoji version 1 of the Unicode Emoji Standard. Technically, it is represented by a single Unicode code point rather than a combined sequence, making it one of the simpler emoji to encode and display reliably across platforms. Its Unicode code point sequence is U+2622.

💡 Good to know: Many Symbol-category emoji have a plain-text Unicode equivalent (from blocks like Miscellaneous Symbols or Dingbats) — the emoji version renders in full color while the plain-text version renders as a simple black-and-white glyph, depending on the surrounding text and platform.
