Another bit of old kit I'd like to display, but can't for reasons: Janitor: "Geoff, we found this in a store, your kind of thing?" I open a burlap case, maybe 1950s, device inside with a dial on top reading in Roentgens. That's for measuring exposure to gamma rays. That kind of thing often has a calibration source. "We're leaving now, locking this door all washing our hands A LOT and I'm going to get a Geiger counter." It was clean, but accidents like that *have* happened.
