Playing with Radioaktiviät - cool.
Alpha particles form the gas or liquid shoot holes in the plastic, then you develop it to make the hole bigger. Take CR-39 Plastic (from laser googles ?) etch it with 7M NaOH, 70°C for 5h ?
1 M NaOH is 40g
NaOH is commonly used to develop photo-resist when making DIY printed circuit boards... so we should have some in the lab.
PMMA/Acryl should work as well...
Can we use the DVD laser scanner to see the holes?
