Radon emissions into room air depend on the gaseous porosity if the 
chemical and physical form of the radium and the thin metallic 
plating over the radium. The plating must be thin to allow the alpha 
radiation to exit. The static eliminator would work best if the radon 
is not readily released since the most energetic alphas are those 
from radon and its short-lived decay products.
