Cloud ChamberIn this image you can see a ‘thoriated-tungsten welding rod’ emitting alpha radiation inside a ’r’. A cloud chamber is a simple particle detector which creates a cold atmosphere of super-saturated alcohol vapour. As a particle is emitted from the rod, it collides with the vapour, causing it to condence back into water droplets, forming these tiny white trails.
