Copy soviet smoke detector "KI-1". In "KI-1" used izotope plutonium-239 and plutonium-241.

so. much. comments. i cant say its spam but it is and isnt

Most smoke detectors I've seen use Americium 241, which is approximately 1'630'000 times as radioactive as Uranium 235, the stuff used to make Nuclear Bombs
-
I've got a 25uCi AmBe(from smoke detectors, it's all sealed don't panic) neutron source in my room doing some neutron activation experiments, but so far I haven't been able to measure anything, so it's probably too weak lol

Neutrons decay into a 1 MeV Photon (gamma rays) if not abosrbed, but because of their mass and charge they dont really do much (unless youre in very high energy ranges [8-10-MeV] like youd see with thermonuclear reactions (such as fusion of hydrogen isotopes) But all in all the term "ionising radiation" is just that. Radiant particles or waves carrying enough energy to "kick" an electron from its atomic "orbit"
-
Also, on an unrelated note, the grating on the smoke detector could be set to VOID with a ctype set to NEUT, so that the neutrons won't escape while the smoke can come in.

Neutrons are quite dangerous and very, very ionizing if at the proper energies. On an absorbed dose equivalency chart, 1.0 MeV neutrons (such as those found in reactors) cause 10.5 times more damage to tissue than an equal dose of gamma rays.

@JasonS Neutrons are ionizing radiation if they are capable of ionizing atoms. Something only needs an energy of 1 eV to be considered ionising.
-
Technically neutrons aren't ionizing radiation. They just make you radioactive which then produces ionizing radiation. I'm pretty sure the neutrons themselves actually do little damage.

i love that joke
