[edusmartin]

TL;DR Summary

I need help to identificate a particle

Hi, my son is fan of the Quantum Physics and we developed a cloud chamber. I'm attaching an image of particle sequence and I will like to find some help to know witch particle is. I will appreciate any help on it. Thanks

It must be charged particles so beta or alpha. Beta has longer and thinner tracks. ref.

Also, it's not uncommon to see muons (and occasionally other cosmic ray related particles) in a cloud chamber.

The average flux of muons at sea level is about 1 per square centimeter per minute.
