Frequently Asked Questions
What does ☢️ mean in a text message?▼
The trefoil radiation hazard symbol, indicating the presence of radioactive materials or ionizing radiation. A universal warning sign for nuclear danger. Use for nuclear/radiation topics, hazardous material warnings, science discussions, or metaphorically for toxic situations. The tone can shift depending on context — a message to a friend reads differently than one to a coworker.
What is the official Unicode name for ☢️?▼
Each emoji has an official name assigned by the Unicode Consortium, which may differ from common names used in apps. The Radioactive emoji's official designation is listed in the Unicode CLDR (Common Locale Data Repository). Shortcode names like those on Slack or Discord are platform-specific.
Can screen readers interpret ☢️?▼
Yes. Screen readers announce emoji by their Unicode name, so ☢️ would be read aloud as "Radioactive." When using multiple emoji in a row, screen readers read each one individually, which can be overwhelming — so use them sparingly in accessible content.
What is the shortcode for ☢️?▼
On platforms like Slack and Discord, you can type `:radioactive_sign:` to insert the Radioactive emoji. On GitHub, the same shortcodes work in issues and comments.
