Abstract
A plasma sterilizer and method employ essentially uncharged, highly reactive free radicals, atoms and excited molecules of a gas mixture to sterilize articles. The gas mixture includes oxidizing and/or reducing agents and is ionized into a plasma having ionization products that include highly destructive components in the form of charged particles and ultra-violet radiation. A plasma distribution device blocks the ultra-violet radiation and facilitates the recombination of the charged particles such that essentially uncharged, highly reactive free radicals, atoms and excited molecules of the gas mixture are delivered to the articles.
