Florian Jörg, a researcher at the Max Planck Institute in Heidelberg and part of the XENON collaboration, has presented a novel technique to reduce radon emanation in materials used in rare event experiments.

By using copper electrodeposition, they managed to reduce emanation rates in steel by over 1000 times with just a few microns of coating.
