Abstract
An apparatus and method for producing positive and negative ions and/or electrons in a gas of any atmosphere without producing dust, a method and structure for neutralizing a charged body in a short period of time and for completely preventing static electricity from being generated, and various apparatuses and structures, such as a conveyor, wet bench, and clean room, which use the neutralizing method and structure. The gaseous ion producing apparatus produces positive and negative ions and/or electrons in a gas by irradiating, with electromagnetic waves in a soft X-ray region, the gas under a high pressure, atmospheric pressure, or reduced pressure. In the neutralizing structure an X-ray unit is arranged at an appropriate place to apply the electromagnetic waves in a soft X-ray region to the atmospheric gas surrounding a charged body.
