JAEA-Testing 2011-007 Guide for Decontaminating Swimming Pool at Schools Quantam Beam Science Directorate, Fukushima Environmental Safety Center, Headquarters of Fukushima Partnership Operations Engineering Services Department, Nuclear Science Research Institute, Tokai Research and Development Center Nuclear Science and Engineering Department Japan Atomic Energy Agency Watanuki-machi, Takasaki-shi, Gunma-ken (Received December 21 2011) Because of TEPCO Fukushima Dai-ichi Nuclear Power Plant accident due to the Great East Japan Earthquake, a huge amount of radioacitive materials was widely dispersed and precipitated into the environment. Swimming pools in Fukushima prefectures were contaminated with the radioactives. We JAEA carried out several demonstration tests to decontaminate the radioactives and discharge the pool water safely. We concluded the results obtained from the tests as "Guide for decontaminating Swimming Pool at School" and released it quickly. Following this, we also released the guide in English. This manuscript, as an experimental report of the swimming pool water decontamination, is consisted from the guide in Japanese and English prepared.
