Chernobyl's Air Is Now 47 Percent Less Radiated with Novel Technology

I buy the part about loosen the soil, not sure about the rest.

Look like they did one pilot, got grant in Switzerland and validation near Chernobyl. Still more validation whether it works at scale.

I'm no nuclear physicist, but the explanation from the article [0] seems to involve only activity in the electron shells, which I suppose might reduce local ionization, but I don't see how it would have any effect on the nuclei, which would still continue to breakdown, so a temporary effect at best?

I'd definitely like to hear from any experts on if this is anything beyond marketing...

The process is conducted safely under the surface of the soil and no radioactivity is released to the ground or in the air. Once the positron comes into contact with the radioactive isotope, it rejoins an electron and annihilates the radioactive matter back to its original matter."
