To provide a continuous decontamination/sterilization apparatus having high decontamination/sterilization effect and high productivity and capable of maintaining reliability and safety of decontamination/sterilization effect with a simple structure, when transferring a package of which exterior surface is decontaminated and sterilized to a sterile operation chamber.SOLUTION: A decontamination chamber decontaminates a bottom surface and side exterior parts of a storage body with a decontamination agent while transporting with a top surface sealed portion sealed by the first transport means. An aeration chamber removes the decontamination agent remaining on an exterior of the decontaminated storage body while transporting with the second transport means. A sterilization chamber sterilizes the top sealed portion of the storage body by irradiating it with an electron beam from an electron accelerator while carrying with the bottom surface or side exterior portion of the storage body by the third transport means. Further, the first transporting means is provided with sealing means having an adsorption function, and suctions and captures the upper seal portion of the storage object so as to seal it, and transports with the bottom surface and side exterior portions of the storage body open.SELECTED DRAWING: Figure 2 【課題】パッケージの外装面を除染・滅菌して当該パッケージを無菌作業室に搬送するに際し、高い除染・滅菌効果と高い生産性を有しており、シンプルな構造で除染・滅菌効果の信頼性と安全性を高く維持することができる連続除染・滅菌装置を提供する。【解決手段】除染室は、第１搬送手段により収納体の上面シール部を封止した状態で搬送しながら、当該収納体の底面及び側面外装部を除染剤で除染する。エアレーション室は、第２搬送手段により搬送しながら、除染後の収納体の外装部に残留する除染剤を除去する。滅菌室は、第３搬送手段により収納体の底面又は側面外装部を担持した状態で搬送しながら、当該収納体の上面シール部を電子加速器から電子線を照射して滅菌する。また、第１搬送手段は、吸着機能による封止手段を備えて、収納体の上面シール部を封止するように吸着して捕捉し、当該収納体の底面及び側面外装部を開放した状態で搬送する。【選択図】図２
