This is interesting but I don't think it would be a valid mitigation method. I remember a few years ago someone gave a presentation on magnetic rods being placed into the basement slab or house slab and electrified them and that helped reduce radon. That did not prove to be effective either. The best method is to set up a negative pressure field under the foundation. This message is tried-and-true and most effective.

What would be the purpose?
And we thought we knew it all.
