It appears that diffusion coefficients for polyvinylchloride PVC are different for various gases ?
I need a diffusion coefficient for a heavier gas (Rn-222) ?
I assume it will take a longer travel time through the material because to the size?
In this case the travel time through the material will also affect the external flux rate as a function of the decay law .693/5500 min.
T1/2 Rn-222 = 3.8 days
Are there any known/established/accepted diffusion coefficients derived from studies of PVC and Rn-222 ?
