Now that's a toy you don't stumble across very often! Not sure what I'd do with it, but others may have a use: https://www.radiacode.com/
Radiacode – Portable Radiation Detector, Dosimeter & Spectrometer

Radiacode is a fast, portable radiation detector, dosimeter, and spectrometer with real-time analysis. 20× faster than Geiger counters, it identifies isotopes, tests food for contamination, and supports research and safety.

@cstross I've nearly bought one a few times - but I have en excuse for it, given I work in a radiation lab.
@dtl @cstross I have one. It is surprisingly good value. However there is a reason why it is marketed to Europe via Cyprus with the real country of origin being conspicuously obscured. Make of that what you will. If you order one. Do get the silicone case, not the fake leather one, and if they still offer… their rubber sealed metal enclosure for protected storage speaks for itself:
@nblr @dtl @cstross that case will get you into a lot of trouble. Joke replicas of "Drop & Run" sources are Not Cool.
@scruss @nblr @dtl @cstross I bet someone made a coffee thermos with the Drop And Run imprint though.
