Abstract
An apparatus for generating air ions. Nuclear air ionizers are utilized which generate a multiplicity of ions of both positive and negative polarity by the bombardment of air molecules with radiation. An electric field is supplied in proximity to the nuclear air ionizers for generating an electrical field of alternating polarity near the source of generation of the multiplicity of ions. This combination creates waves of ions of opposite polarity which assist in moving the air ions away from the ionization source and preventing early recombination. An air ionization system for entire room or enclosure may be constructed utilizing a grid of a plurality of spaced apparatus as described above. Optionally, an air stream may be utilized to assist in moving the air ions created to a target surface.
