There isn't a lot of toxic material on a modern phone.

The thing about radioactive material is that you need very little of it to become a serious contaminant. But as the thread is about, you also actually need very little of it, so it really doesn't look that out of place.

Another issue is that radioactive material emits energy, what is harder to handle than inert contaminants. You don't want all of that trash with uncontrolled material to catch on fire.

That said, I do agree that our previous carelessness around things like lead and mercury were much more harmful. It's just that we are best careful with both, and the past actions do not excuse doing a harmful thing now just because it's less harmful.

That “a lot of” is doing a lot of work in that sentence. By mass? By how toxic it is to humans or the environment?

This is pretty old and I know the industry has tried to eliminate a lot of them from the phones so I don’t know what the current state is: https://www.cbsnews.com/news/study-finds-phones-still-contai...

Here’s an article about research showing that toxic materials in screens are leeching out even during normal use: https://www.cbc.ca/news/canada/saskatoon/research-sask-chemi...

Finally, the chemical processes involved in the manufacturing of the phones themselves also involves large amounts of toxic materials which is still challenging to manage even if it’s centralized (it’s just an “over there” problem because we outsourced a lot of manufacturing).

As for the rest, it’s unsubstantiated hypothetical fears. Really the only risk you actually call out is fires but ignore that, for example, lithium ion batteries aren’t inert either and can also cause fires when damaged. You need to compare and contrast risks correctly, not just worry about hypothetical scenarios and use radiation as a scary boogeyman when it’s actually a significantly more nuanced topic.

As I said, if the battery remains useful, it improves the purchase price of a phone to be discarded because the battery can be recovered and resold for another device which improves the story vs traditional batteries that we basically trash after a few years.

On your first link: "Overall, newer phones were less toxic than their older counterparts".

That's the thing, unless we have a very good reason, we should improve things, not make them worse.

Also, the stuff your second link talks about lasts for a decade or two at the environment, and then it's gone. While the fire risk of batteries lasts for a year or so.

A very good recycling program is a way to use make widespread use of those things. A very good protocol for handling them as trash is also one. But just landfilling them in mass isn't.

You have to take a systemic view. Fewer batteries going into the landfill and not needing any of the toxic industry involved in making those batteries could very well be a better trade off, especially since the battery can be reclaimed and repurposed elsewhere. I think this “it has to be an improvement on all fronts” attitude is actually harmful to making forward progress. And “less toxic” is also information-free because it’s not quantified nor is it a systemic analysis because that kind of analysis is quite hard to do. So yeah, it’s very possible that a radioactive battery is net better than chemical ones. It might bring new challenges but that’s true of all tech improvements.
