Very wrong.

> A 1992 episode of Captain Planet and the Planeteers depicts a somewhat loosely-based version of this event in the episode "A Deadly Glow," albeit with a happier ending for all involved, and blaming the contamination of the town on an eco-villain. However, it did feature caesium-137 as the radioactive contaminant, as well as portrayed two young children unwittingly playing with it in a similar manner to Leide das Neves Ferreira, who, unlike the children in the cartoon, received a fatal dose.

Fascinating

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-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.

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

Too similar to https://www.gjplastics.co.uk/fire-exit-sign/ ?

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 was thinking about storing small parts and such in them.

I can only see that ending badly.

Not 24 tonnes of radioactively contaminated dust badly, but still.

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

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

Meth is powerful and apparently common in Thailand. That said, the scrap dealer ought to be informed and quickly run the other direction when a tweaker walks in with a radiation source.

Repeating an old comment by myself:

Some idiots are using the extremely scary-looking radiation symbol (or something too similar) to sell soda, for example:

* https://www.amazon.com/-/es/Radioactive-Mulberry-Marciano-In...

* http://rad-60.com.ar/ [1]

IIUC this is just water with sugar and a fluorescent dye, not radioactive material (except the natural amount of radioactive deuterium and potassium, that is not enough to make it glow).

[1] Thanks to kragen for the second link in a reply in my old comment. I remembered the advertisement in tv, but I couldn't find the exact name or webpage.

Is that idiocy even legal? We had the mirror case at a previous workplace once, when an arts class drew artsy warning signs, but then they hung them up in the Science Building to serve as genuine warning signs. Several "Emergency Exit" signs went about the doors, there was a neat "Inflammable" sign on the steel cabinet for solvents & so on.

They probably thought "eh, there's no way they'd throw it away with the dangerous parts included".
