Science Experiments / How do you construct a home-made cloud chamber?

Hello!
This is my first post here. I am a digital artist who develops interactive learning for science and engineering subjects, hence my ID. Today, I built a simple 'cloud chamber' to detect atomic particle tracks--a photo is below. The particle source I used is a small button of Am-241. Most of the tracks I observed seem to be either straight (alpha?) or curved (beta particles?). The one exception is the bulls-eye pictured below, with two lobes (arrows). I have never seen such a track in a cloud chamber--do you have any idea what it is?
