Emoji Meaning

1

A bright fluorescent orange or yellow circle with a black, three‑pronged trefoil at its center — the universal symbol for radioactivity. It warns that highly radioactive and potentially dangerous materials may be present in the area.

2

The radiation symbol shows a three-bladed fan—typically black or white—set against a yellow or orange background. Radiation itself is invisible and highly dangerous, so exercise extra caution if you encounter this sign.

The mark resembles the biological threat symbol. It’s often called nuclear and points to places or objects that cannot be approached.
