please use turbo mode by pressing [shift+green flag] you can drag the sample of uranium around Thick and short paths are low to medium energy alpha particles. Thick and medium paths are high energy alpha particles. Thin and medium paths are high energy beta particles. Thin and wobbly paths are low energy beta particles. Long smooth and moderately thick paths are proton particles.
This simulation is a rough approximation of cloud chambers, these are chambers filled with a super saturated alcohol fog designed to react and show the extremely tiny particles of radiation. V0.1.0
