I have to say, I do not know that answer. Damn it cyberrigger, now I have to find out how smoke detectors work before I’ll be able to sleep.
They come with an Alpha radiation source (easily blocked by smoke).
This radiation passed through air.
A detector looks for a drop in radiation, because of smoke.
Oh, so it’s a question you already knew the answer too you sly dog, I see how you play the game.
Don't you remember the "safer" radioactive watch dials that used alpha particle radiation to glow? ----- instead of the old, dangerous radium dials (beta and gamma radiation)?
Alpha penetrates the least
Beta penetrates more things
Gamma ----- this shit goes through everything
Alpha stops at your skin
I alway’s wondered how dangerous those radium dials were. I know they make replacements for watch repair. Damn it cyberrigger! Now I have to look up the half life of radium and it’s rad count.
