"Or something"... I bought some tritium vials for much too little off AliEx a while back. I had them earlier today; I'm sure they'll turn up. I don't think they'll set off a Geiger Counter; but I know for a fact my little vial of old Timex watch hands will, even as dim as most of them are now.

And this is why this forum is such a time sink...
mnen says, quite innocently, i misplaced some radioactive isotopes and, of course, i take the bait. and then he says, i bought some tritium vials for much too little off AliEx a while back and now i am off and running... what do you use tritium vials for? and why are they on AE? and suddenly I find myself in a twisty maze of prepper/edc forums all alike.
... and the night is gone.
edit: and that's before i notice, "my little vial of timex watch hands". huh? what did you say? wha...
Before tritium vials, we had radium-phosphor paint. Among many other things, it was used for the hands and dials of wristwatches; and it is the reason why during wartime, officers were issued watches with covers like these. Not to protect the expensive watch but to keep them from being used as a target for night-snipers. They were also the origin of the phrase "(Never )
Three on a match"; this came from field-training lectures where infantrymen were warned that a night-sniper would spot your trio of smokers on the first light of a cigarette, range in on the second, and start shooting with the third glowing coal and match-illuminated face.
New toy arrived. I rather like this. Display clarity/angle is better than the TF930 and no futzing with level control - just works straight up!
Nice toy, and nice Manhattan-deadbug hybrid construction. Dumb question... When I learned the technique, we were taught to "solder the islands" to the ground plane to prevent unknown/varying stray capacitance created by gluing them down. We did this by dropping the chip of double-sided PCB them on a dot of flux and wicking solder underneath. That usually leaves a telltale patch of solder on the ground plane on one side of the island. Since I've been here, I've never seen that on your projects, even the ones done with proper Manhattan construction. Is that just you being in a hurry and super-gluing them down, or is that "common knowledge" something that has changed since the stone age when I learned the technique?
Also, please tell us more about your new toy... How much, where from, etc.
