affect of alpha and beta particles on metal

[Guest lawton20]

Can someone answer a few quetions for me?

 

1) What is the affect of alpha particles on a metal when they are stopped? Are they reflected? Where do they go? Do they steal some electrons and become helium? Thus ionising the metal?

 

2) what is the affect of beta particles on a metal? Are they incorporated into the electron cloud of a metal latice model? where to they go when they are stopped?

 

Thanks

Alpha particles and beta particles both ionise and penetrate metals.

Penetrating power of beta rays is more than alpha rays but alpha rays have a greater ionising power.

Yes, they will ionize things. But the original nucleus the emitted the particle has a different charge as well, so overall the charge remains constant.

Has anyone heard the latest on the situation with neutrinoless double beta decay. If it occurs then aren't there major problems with the standard model of beta decay?

if thats the case, which is quite logical that the overal charge stays the same, when a charged particle, alpha or beta is ejected from a source, were do the balancing charges come from?

 

Say there was an alpha particle emission sorce in water or near it, with a metal submersed in the water, is it possible the metal would ionise and go into solution? or would the charge buildup prevent it?

The parent nucleus has the excess or defecit of charge (depending on whether it's alpha or beta), though some electrons might get shaken off during the event. But total charge is conserved.

 

Charge can build up where the particles hit, which is how some dosimiters work - the buildup of charge on metal causes the charges to repel, and the amount the metal strips separate is proportional to the dose.

neutrinoless? No I havn't heard anything on this, I thought beta decay always produced a neutrino. Have a linksy?

Neutrinoless double beta decay does indeed involve physics beyond the standard model. Google on 'majorana neutrino' and you'll probably find more.
