@gsuberland What the hell is going on there :D
Apparently someone dropped off three devices with Am-241(an alpha emitter) in the swap meet, and now the question is who picked up one of these devices. (https://meow.social/@tryst/112547040034336222)
(Am-241 is/was often used to ionize air, e.g. to allow smoke level measurements because smoke will reduce the "level of ionization". This was a repetitive headache when those smoke detectors were left alone, stolen, thrown out in trash, smashed open by disgruntled employees, etc.)
Right, I misunderstood "we've found two and are looking for more" (in reality looking for more was out of caution and not a strong expectation that there should be more).
