diffusion cloud chamber @ spektrum berlin

a cloud chamber in action!
the long lines are beta particles, the short thick lines are alpha particles.
oh yeah, and the stuff in the beginning was americum in a tube and a uranium ore rock, followed by a radioactive incandescent mantle. :-)

Nebelkammer ist was Spanendes - Leider kann man die Spuren so schlecht Filmen

@MorganOthelloLafay

stimmt, leider - in meinem neuen video ist mir das aber um einiges besser gelungen (neue kamera): watch?v=Efgy1bV2aQo

Deutsches Museum in München?

[bionerd23]

nein - siehe titel, "spektrum" im technikmuseum berlin.

would anything happen if you put a piece of radioactive material, like that uranium you have, near the cloud chamber?

[bionerd23]

nope, i have tried. :-D

as those ionisation tracks inside the chamber are from a radioactive gas within the chamber, and demonstrations with more radioactive material inserted into the chamber from the bottom are possible, i think the cloud chamber is made out of lead glass to protect the viewers. that will also shield anything from the outside, too, of course.

otherwise, you would in theory see a really heavy stream of betas and alphas coming off of the uranium ore.

hmm, well, in theory, yes... the problem is that a cloud chamber is a 'closed environment'; by the time you 'power it up', the radon in the air you sealed inside the chamber probably has decayed. i'm not sure if you could 'pump' some 'fresh' air in without ruining the super-saturated environment, hmmm... then again, there may be enough decay products of radon 'floating around' inside the chamber to notice, anyway.

[AScannerClearly]

I could watch a cloud chamber all day long... who the heck needs a TV? ^_^ Sure it would be a good way of measuring radon in the air too.

im from berlin. i get my uranium ore from abandoned mines in saxony, see my 'finding uranium in nature' video for details.

[Ballpythondude420]

where do you live germany? where do you get your uranium ore?
