In other words, we are creating something human history -- as well as contemporary events -- demonstrate we do not have an enduring ability to manage.
As they say, we can't put the genie back in the bottle. But we can perhaps do something to limit scope, particularly where alternatives are developing that are safer and, sliding down the development cost graph, more cost-effective.
P.S. I'll add that, until we can manufacture elements (more fully), I prefer to keep these limited resource available for potential future use, when we have acceptable alternatives -- for me, now, meaning solar, wind, hydro (all forms of solar energy, essentially).
Who knows what need we might have of them, in the future? What if really going to space requires them in significant quantity, but we burned them all up on street lighting and casinos? ;-)
(Wouldn't it be ironic if further sources were in space, but we didn't have enough to get there?)

"Even today, radiation levels are so high that the workers responsible for rebuilding the sarcophagus are only allowed to work five hours a day for one month before taking 15 days of rest. Ukrainian officials estimated the area would not be safe for human life again for another 20,000 years" - https://en.wikipedia.org/wiki/Chernobyl_disaster citing https://en.wikipedia.org/wiki/Chernobyl_disaster#cite_note-T...

The problem is with long half-life (and thus low-radioactivity) elements that sit on the trees, get mixed with soil, and thus eventually end up in ground water and local food chain. You might be able to walk around a disaster site safely in relatively short time after the event, but I wouldn't try growing anything there.
Anything that went wrong with the Hanford Site can go wrong with any nuclear power factory.
It's the profit and human error factors...
Not sure how many techno-naive pro nuclear factory people know that in the real world (as opposed to the fantasy world where technology is all that matters), nuclear waste is giving to MAFIA owned companies to dispose, which then save money by just dumping it in the ocean...
Not joking:

and that's the tip of the iceberg... Even worse in the developing world...
Quick look at their website says it's not available to the general public. Only government officials, students, etc.
Tours of the Hanford site are available to US citizens. Highly recommend people also go to the Manahatten Project “B Reactor” out there which is available to everyone.
