On 16 June 2012, I measured radiation in " Kameari Park " of Katsushika-ku, Tokyo, Japan. I monitored 0.17 micro Sievert per hour in air at my breast-high, 0.30 on a bench of the park. Moniroring point is 210km from Fukushima Daiichi Nuclear power plant, and only 10km for the center of Tokyo. Measuring instrument is made of Ukraine, ECOTEST MKS-05. It is said that the park is model for a popular animated TV show "Kochikame". 0.30μSv/h こちら葛飾区亀有公園 のベンチ 2012年6月
