John Lambies Doos Posted February 13, 2018 Share Posted February 13, 2018 Hi All.If alpha radiation is released from a source, does it stick to surfaces or does it just disperse? I'm not talking about ingesting/inhaling the actual source rather the rays the source omits Link to comment Share on other sites More sharing options...

If alpha radiation is released from a source, does it stick to surfaces or does it just disperse? I'm not talking about ingesting/inhaling the actual source rather the rays the source omits There's no such thing as "alpha rays". Alpha radiation is particles emitted from a large atom. Their structure specifically is two protons and two neutrons; a Helium nucleus. The likelihood therefore is that it'll end up forming a Helium atom eventually when it steals itself a couple of electrons. IIRC most of the helium on Earth comes from alpha decay. Alpha particles themselves are not particularly dangerous unless the source is ingested; they struggle to penetrate paper never mind skin/clothes.

John Lambies Doos Posted February 13, 2018 Author Share Posted February 13, 2018 They don't, they emit alpha particles.Ah OK. . And is this dangerous ie do they sit on surfaces? Link to comment Share on other sites More sharing options...

And is this dangerous ie do they sit on surfaces? They get absorbed by the air within a few centimetres and by the alarm structure itself. All you get is a tiny amount of helium in the air. http://firewize.com/node/24 Link to comment Share on other sites More sharing options...

Anyway, whats this all about? Is JLD having a tin foil hat "the smoke alarm is out to get me" moment? Link to comment Share on other sites More sharing options...
