On December 10, 2011, Dr. Norio Abe did a radioactive cesium decontamination experiment by the nano silver at an kindergarden in Koriyama city of Fukushima prefecture in Japan. Dr. Abe sent me the result data, then I try to make a summary of the experiment.
1. Outline of the experiment
On December 10, 2011, at an kindergarden in Koriyama city, Dr. Abe did the experiment at the same time as the water washing of the roof for decontamination. He used the filtration device called “Lucy”, that has four stages of filtration including nano silver supported by bone charcoal and white granite.
He filtered cesium contaminated water three times by Lucy. Each time the value of radioactivity of the filtered water was measured using a germanium detector by a professional company.
As a result, the radioactivity of the water was reduced to 1/10 as compared to the initial value. Furthermore, he measured the radioactivity of the used filter in 8 days at Itabashi Firefly Ecosystem Center, and it was reduced to less than 50%, too.

3. Experimental results
The following values indicate decontamination level of the water (Bq / L) after the three times filtering.
| （Bq/L） | Initial | 1st time | 2nd time | 3rd time |
| Cs-134 | 13300 | 1840 | 1350 | 1340 |
| Cs-137 | 18800 | 2490 | 1910 | 1830 |
After the experiment, he carried Lucy to Itabashi Firefly Ecosystem Center and measured the radioactivity of the filter. The following values indicate the radioactivity of the bone charcoal and white granite including nano silver.
The measurement started at December 11, while the experiment was done on December 10, then the initial value of radioactivity might be higher than 0.56 μSv/H. Further, as the background radioactivity was not measured, the background value was not subtracted.
The result is very impressive because it seems to show nano silver can decontaminate the radioactivity of Cesium in a real situation. I hope other scientists may pay attention to the experiment and will try to reproduce these results.
