The woman sitting next to me on a flight this afternoon seemed troubled when I produced a geiger counter that was clicking away. I wasn't sure how to explain "I just want to see the radiation levels increase as we ascend higher into the atmosphere" without it becoming a Whole Thing so I just shrugged as if perhaps I'd found it in the seat back pocket, and put it away.
"Why do you have a geiger counter, Waldo?"
They're, like, fifty bucks! How can I *not* have one, at that price point‽
@waldoj I have a fair number of devices for exactly that reason
and a thoughtful holiday gift for friends near the front lines in the Donbas.
-- sorry, maybe all that saber-rattling finally rattled me , too.
