I Help getting my Cloud Chamber to work please

TL;DR Summary

I've built a cloud chamber, I have saturated isopropyl alcohol layer, but no radiations are showing.

Hello!

I'm currently building a cloud chamber, my end goal is to make it powered by Peltier chips but that won't happen until I can make it work with dry ice. I've been able to achieve a supersaturated layer of isopropyl alcohol in the chamber, however, even with very radioactive uranite (≈45000cpm) and with less radioactive uranite (≈1000cpm), I'm not detecting any trails. Super conflicting as I have a great alcohol layer... anyone have any idea what might be going on?
Also, is a HV power source absolutely critical, idk, something with putting HV in a pure alcohol atmosphere just doesn't sit right for me.

Here's what it looks like, doesn't show much or help much but just in case. This is with it on btw.

P.s. ik it would be easier to see the trails left behind on a black backdrop, I tried on one, still nothing, I’m using aluminum foil here for better contact with the dry ice hoping that would help
