<p>A novel reaction chamber is described for the treatment of gases which either have a noxious odor or include toxic elements. The chamber is for treatment of the gases with energetic electrons and uses an extended electron source in the center of a chamber volume which creates electrons that move out of the source and radially into the chamber. The gases are flowed into the area of the source and away from the source as to result in uniform and efficient exposure of the flowing gases.</p>
