Abstract
A sterilization method for organic or inorganic matter which combines exposure to ultraviolet light and ultrasonic waves. The ultrasound waves are applied "dry" in that the object is not immersed into a liquid solution during the exposure cycle. This makes the sterilization method suitable for use in a mass production assembly line setting. Exposure of the object to the ultraviolet light and ultrasound waves can occur simultaneously, sequentially, or in alternating fashion.
