Abstract:
PROBLEM TO BE SOLVED: To solve the problem that when an air filter contaminated with a radioactive substance floating in the air includes an unburnable member, it is necessary to: classify the contaminated air filter into at least a burnable member and an unburnable member in waste treatment; prevent a danger to a human body during the classification; and obtain a storage space of the contaminated filter.SOLUTION: An air filter contaminated with a radioactive substance floating in the air is washed by a cleaning liquid, and the washed radioactive substance is caught by a specified filtration body. The contaminated air filter can be cleaned for each site by mounting a set of apparatuses required for cleaning the contaminated air filter to catch the radioactive substance on a movable vehicle, and storage or movement of the air filter on the site is not required.
