Kleinstein:
The detector in the radiation monitor is not a classical Geiger tube, but a small scintillator with likely a photodiode read out (not the classic photo-mulitplier like in the larger ones). So not high voltage needed - maybe some 50 V for an avalanche diode. That is a really fancy and sensitive detector. A question may be how good it is with more soft radiation (e.g. lower energy X-ray like from a CRT).

The spectrum would likely need some time and maybe a reset to remove to old data from the spectrum. Chances are the curve shown is from the background and only little from the smoke detector.

Alakis:
Does anybody know where to find radiation sensor as in the RadiaCode? I've been wanting to build a radiation sensor of my own, but can't seem to find discrete radiation sensor modules anywhere. Thanks!

KE5FX:
If that LattePanda is like their previous generation that shipped with Windows 10, that's actually a fully-licensed LTSC IoT build.  Worth the price of entry for that fact alone, IMO.

alxpo:
IIRC they designed the sensor. In addition, it is difficult to understand gamma spectrometer signal processing without specialised education and at least 5 years of experience.
