Abstract
A decontamination device devised to accomplish decontamination with a proper amount of decontamination agent by employing a mist control mechanism to concentrate a mist for decontamination on the surface of an article to be conveyed, and to reduce duration of operations such as aeration increase efficiency of decontamination, and a pass box in which the decontamination device is disposed. The device also includes a mist supply means configured to convert a chemical for decontamination into the mist, and to supply the mist to the inside of a working chamber accommodating the article. The mist control mechanism includes vibration boards adjacent to internal wall surfaces of the working chamber, which are ultrasonically vibrated to generate sound flows from board surfaces by an ultrasound in the vertical direction. The mist supplied to the inside of the chamber is pressed by acoustic radiation pressure to be concentrated on external surfaces of the article.
