Looking at various tracks, there is clearly spiral motion in the cloud chamber, which combined with the normal convective motion seen in cloud chambers, could impose some odd distortions of the tracks. There is no mention of whether you are using the typical electrical field to stretch out the...

DIY cloud chambers with readily acquired magnets easily show spiral tracks, for example, from
the beta decay of cesium 137 as in this video. The...
Geiger counters around Fiestaware (about 14% by weight uranium in the glaze of the depression era orange-red version) catch mostly beta radiation, according to the literature I've seen. I worked in a museum for 3 years with a cloud chamber. It typically took about an hour after startup to...
There is online literature on cloud chamber tracks, explaining why alpha rays are so short and dense, muons are so long and straight, and betas are so irregular. Just do a WWW search. Some of these sources date derive from 80+ years ago, back when Wilson cloud chambers were at the leading edge...
