TEPCA: The results of nuclide analyses of radioactive materials in the air

Press Release (Apr 16,2011) The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (22nd release) On March 22nd 2011, as part of monitoring activity of the surrounding environment, we conducted nuclide analyses of radioactive materials contained in the air which were collected at the site of Fukushima Daiichi Nuclear Power Station, which was damaged by the Tohoku- Chihou-Taiheiyou-Oki Earthquake. As a result, radioactive materials were detected and therefore, we summarized the results and reported them to Nuclear and Industry Safety Agency ("NISA") as well as to the government of Fukushima Prefecture. The three nuclides (Iodine-131, Cesium-134 and Cesium-137) are to be released as fixed figures, and the other nuclide figures are to be revaluated in accordance with the preventive measures formulated after the warning from NISA on April 1st. (previously announced) On April 15th 2011, we conducted a nuclide analysis of radioactive materials contained in the air which were collected at the site of Fukushima Daiichi Nuclear Power Station on the same day. As a result, radioactive materials were detected as described in the exhibit. Accordingly, we have reported the result of the analysis to NISA and the government of Fukushima Prefecture. We are planning to conduct these surveys continuously.
