Radon: origin, health effects, measurements, Marco Silari, CERN:
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?
And could we use a DVD as detector material (Polycarbonat)? And how about modifying a DVD player to read the holes? And using old CDs or DVDs from a cellar to determine the radon concentration? Make it a community science project?
People have looked into this before: Application of polystyrene films for indoor radon dosimetry as SSNTD
Radon mapping by retrospective measurements – an approach based on CDs/DVDs
echt geil
How about Electrochemical etching or Ultrasonic etching?
Let's try and meet at SDG Solution Space in Geneva for "Open Hackuarium 228 "Sans les murs" #2, Spécial Genève"
