Which is one reason why the IAEA introduced a new symbol for use on interior components of radioactive sources: https://www.iaea.org/newscenter/news/new-symbol-launched-warn-public-about-radiation-dangers https://www.iaea.org/newscenter/news/new-symbol-launched-war... Even if you don't know what the radiation trefoil means (a lot of people interpret it as a flower or a fan), the added message of "death, run away" is pretty clear. And, unlike the existing radiation symbol, this one is reserved for use in places that most people should never see (like inside radiation therapy devices), so there's little risk of people becoming accustomed to seeing it.

Now that's good UI design... wavey lines, black skull on red background, GTFO!

to me the added message reads more like "death, exit"

I think this is a good move, this symbol has the same problem that the biohazard symbol has. Not sure if the trefoil was designed under the same rationale as the biohazard symbol, but at least in that case, I think the idea to make a new symbol that is recognizable but with no existing meaning is a bad idea. People end up putting it on t-shirts because the symbol looks interesting but never learn what it means. It ends up both losing its impact and not conveying anything inherently.

  But it's hard to gauge how dangerous something is. Radioactive sign? Is it on an old smoke detector? Sure, it technically is radioactive, the sign is there, but the danger is on "meh" levels. And the size of that is relatively similar to the capsule lost recently in australia, which indeed was a lot more dangerous. Biohazard sign? Could be a smallpox sample... also could be an old bag of used tongue depressors. Firs one would cause (another) global catastophe, and the second one can be safely cleaned in most dishwashers on the "normal"/high heat setting.

    > Could be a smallpox sample... also could be an old bag of used tongue depressors. Yeah, no joke. I have boxes full of baggies with biohazard signs on them because I needed to do daily covid tests for work and each come with such a bag. I have so many of them that i was thinking about storing small parts and such in them.

      I have the board game pandemic, and I used these bags to store the infection counters.
