PROBLEM TO BE SOLVED: To provide a tube decontamination tool which is capable of easily decontaminating the inside of a tube having an arbitrary inner diameter and of reducing amount of secondary waste generated by the decontamination.SOLUTION: A body part 11 comprises an expansible member 13 having an approximately cylindrical outer shape and a decontamination liquid carrying member 14 arranged so as to surround the outer periphery of the expansible member 13. An operation member 12 is fixed to the center of one end of the expansible member 13. The expansible member 13 is a hollow air bag which is capable of sealing gas inside and is constituted of an expansible elastic film such as a rubber or an elastic resin film. The expansible member 13 is expansible in such a manner that at least its diameter Rc changes by adjusting amount of gas G, such as air, injected into it. |
