Yep, some tinkerer would drill holes in the thing, maybe to fix it to the wall or something
There was a nice program on a German TV info channel, what was it called? 'This is Uranium"?
where they go back in time and show 'Pechblende' stored outside mines as 'worthless' (Pech in German means 'bad luck' in English)
because they were mining for something else... to Marie Curie and many scientists involved in understaning Uranium to the nuclear bombs on Japan.
It also made me wonder why Iran does not have the bomb yet, if the recent earthquakes there were nuclear bomb tests.
I mean they had ultra centrifuges for years, Siemes PLCs controlled that were then hacked to stop them .
Sure possible, but I worked with Siemens PLC guys for years,,, just wonder.
An other US game?
Or will is-a-hell be nuked into oblivion shortly ?
Trump seems to be anti-Iran?
US CIA now starting new wargames in Syria...
 radiation is interesting, was reading that gamma spectrometer group many years ago,
  https://groups.io/g/GammaSpectrometryGroup
building my own, playing with stuff:

WOW! time flies! Was 2010 or earlier.

I still have my gamma spectrometer and GM counter next to me on the table...
