On April 12th 2011, in order to examine the condition of the spent fuel
pool of Unit 4 of Fukushima Daiichi Nuclear Power Station, we collected
200ml of the water in the pool with the concrete pumping vehicle.
On April 13th 2011, we conducted a nuclide analysis of radioactive
materials with the water and as a result have detected some radioactive
materials as shown in the exhibit.
We are planning to evaluate the result in further detail.
