They are called source disks.....they are about $70 - $120 USD each and can be bought...as long as they are the isotopes are legal in 'exempt quantities' in your country. However you'll probably have to import them and finding supplies who ship internationally (most come from the US) is difficult.

i'm not sure; i used to have about 25.000 / 24 hours, but now they're a lot less... a couple thousand at max, maybe 2000 or so.

wow great videos, I'm glad I found your channel!!! just out of curiosity, how many extrasystoles do you have in a day?

Mir ist das auch ein Rätzel. So etwas haben wir auch schon in der Schule gemacht und ich habe meine Biolehrerin auch schon Kaninchenherzen mitgebracht. Da ich züchte und diese auch geschlachtet werden.

@GWGW93
wahrscheinlich, weil du in deinem account eingetragen hast, dass du noch jung bist. :P
sowas macht man ja auch nicht bei youtube, man ist IMMER mindestens 21! ;)
...hintergrund: das video wurde als "not suitable for minors" geflaggt. keine ahnung wieso - denn teile von tieren seziert habe ich schon in der schule, mit 14... so wie die meisten anderen auch. insofern... *schulterzuck*

Hey, warum kann ich das Video mit dem Herz nicht sehen? Das ist doch eine Schweinerei!
