Abstract
The flexible container bag using the zeolite functional paper, which supports natural zeolite powder, as an inner package was newly developed for the countermeasure against decontamination of the radioactive cesium from the accident at the Fukushima No. 1 nuclear power plant. First, the feature, the specification, and the example of application were shown. A series of filtration tests was conducted for a suspension of soil contaminated by radioactive cesium, and suspended solid and the cesium concentration of filtrate water were measured. Based on the test results, the effectiveness of the simple filtering method using the new flexible container bag with zeolite functional paper was confirmed.
