Скачать или смотреть radioluminescent toggle switch inside peltier cloud chamber

The first 49 seconds of the video shows particle tracks produced by a radioluminescent toggle switch placed inside a peltier cloud chamber. You can see part of the switch's reflection if you look closely. These switches were made for aircraft at one time and used a radium based compound sealed in a small ball at the tip for better visibility at night. The tracks you see are mainly from gamma radiation emitted by the radium. The switch is rather large, so most of it does not appear due to emphasis being placed on better track appearance.

At 50 seconds starts tracks emitted from a small piece of uraninite or pitchblende.
