Has anybody done testing on how well various materials can prevent the passage of Radon gas? For example, a container made of thin low density plastic will apparently gradually permeate out Radon, but a high density plastic container will not. Other materials I have in mind are rubber, electrical tape, sheet aluminium or silastic goo.
I am asking this because I am making up containers to retain Radon emissions from sediments for the sake of measuring the Rn-222 activity and hence the sediment's parent Ra-226 activity when in eqilibrium.
A further question: If I have a material that permeates less Radon than is produced from the contained sediment, will the Radon:
1. gradually reach eqilibrium with Ra-226 (the parent) over a longer period of time
2. reach eqilibrium at an activity lower than the parent Ra-226.
3. not reach any equilibrium at all.
4. none of the above!?
