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"
