how to build a geiger counter / radiation detector from household materials

READ THIS DESCRIPTION for background information, i.e. how this device works at all (see links below)!

ps: technically, this is NOT a geiger counter. a geiger counter is a special type of ion chamber that runs on very high voltages. the device demonstrated in this video is just a very simple ion chamber.
