alt Hacker NewsWoah, this doesn't sound like over-reaction but the reporting doesn't give enough details to know:
>While his actions were criminal, the judge concluded that Lidden had mental health issues and displayed no malicious intent.... The delivery of the materials – which included a quantity of plutonium, depleted uranium, lutetium, thorium and radium...
Seems weird that the judge said Lidden had mental health "issues". Who knows how severe or debilitating the so-called mental health issues are? Not sure how the judge can make that decision on his own, about Lidden's mental health excusing him for doing something "criminal", although one wonders too how well the 1987 nuclear non-proliferation law was written, and if it was even applicable given small amounts Lidden possessed.
Key question is Lidden's purchase amounts of plutonium, depleted uranium, lutetium, thorium, and radium for his home periodic table display. (I totally understand the motivation for wanting to do that! I would love to have every element, even a tiny bit, for that reason too.)
Plutonium seems most concerning. It doesn't exist in nature but Pu-239 is the by-product of Uranium-238 used for fuel by nuclear reactors. (Not certain about isotype numbers.) Lidden bought depleted uranium, so that's more okay... I guess. (Don't know what its half life is even after "depletion".) Pu-239 and Pu-240 half-lives are thousands of years. Due to the radioactive alpha decay of plutonium, it is warm to the touch!
I wonder if he even had real plutonium, because even the non-weapons grade costs at least US$4,000 per gram.
Final thought: Chemical toxicity of (undepleted) uranium U-238 is comparable to its radioactive toxicity. Chemical toxicity of plutonium Pu-239, Pu-240 etc. is minor compared with its radioactive toxicity. By chemical toxicity, they're referring to the tendency for plutonium to spontaneously combust if exposed to moisture, or in hot humid weather. It can even catch on fire when submerged in water.
EDIT: Reduce verbiage

Plutonium was in form of an old soviet smoke detector, containing micrograms of it. This case is whack.
> half-lives are thousands of years
This means it isn't very radioactive at all.

Perhaps the judge made the determination based on evidence, such as testimony from experts? I don't know but does anyone else here?
When I was in grade-school, my classmate's father was a collector of model trains. And he was, in fact, so avid and dedicated with his collection that every shelf and available space in his home was filled with those model trains. I indeed visited them a couple of times and, being the grandson of a railroader and owner/operator of a Lionel set myself, I was quite awed by the variety and cool stuff on display. In fact, his daughter once visited another friend's home, and she was utterly mystified as she looked around, asking "but where are the trains?"
Now there is surely a fine line between obsession and dedication in a collector's spirit, and this particular fellow became quite successful in real estate, so that he was able to open up a storefront in a very busy area of town and dedicate the space as his "private museum". By that time he had branched out into collecting automobiles, yes full-size ones, typewriters, purses (his wife liked those), phonographs and all sorts of other amazing, mostly mechanical, wonders. He took over for the local model train shop just down the way. So anyone in the market for a train set can also linger for a gander at his comprehensive museum setup.
So I am unsure if his obsession presented any sort of disability; he certainly ran a business, had a good wife and children (who also ran businesses), and he was eventually able to parlay this collection into something quite public, if only a breaking-even "vanity project" where his friends dropped by.
So, like, I would never discourage someone from cultivating a cool collection of stuff at home if there's a chance it turns into something like that. But just piling on ugly radioactive waste in your bedroom? I'm not sure that's a sane decision. I'm not sure that's something I would pay to see, or even come over for lunch. I would nod, smile, and call some hotline on the guy, myself.
You’re questions are already answered in the article:
1. The items were on display in this bedroom
2. The quantities were so small that they were deemed safe to eat.
This sounds like more of a case of the border force wanting to raise awareness rather than any actual danger being presented
