Readings of Radiation Monitoring of Outdoor Swimming Pools at Schools, etc. in Fukushima Prefecture (Preliminary Report)

August 30, 2012 Local Nuclear Emergency Response Headquarters (Radioactivity Team) Disaster Provision Main Office of Fukushima Pref. (Nuclear Power Team)

1. Monitoring date June – September, 2012 (Monitoring was partially conducted in advance according to usage of the swimming pools)

2. Target facilities Number for this report Number of target (Those monitored from August 16 to facilities (*) August 23)

492 114

* Number of the facilities that requested monitoring as of August 29, 2012. * The results of the monitoring will be released sequentially from those for facilities whose measurement results are organized and made available.

3. Monitoring results (Preliminary report) Analyses of radioactive cesium of the water in outdoor swimming pools at schools, etc. There is no facility where the level of the radioactive cesium detected is higher than the control target value for tap water (radioactive cesium 10Bq/kg). Not detectable – 1.98Bq/L (Not detectable in 107 facilities out of 114) Cs-134: Not detected in any of the facilities Cs-137: Not detectable – 1.98Bq/L

4. Handling of monitoring results As for the use of outdoor swimming pools at schools in Fukushima Prefecture, the Ministry of Education, Culture, Sports, Science and Technology issued a notice on April 10, 2012, which indicates that there is no problem with using tap water controlled under the control target value (radioactive cesium 10Bq/kg), and it is not necessary to restrict the use of outdoor pools even if the level of the radioactive cesium is a little over the control target value. In cases where radioactive cesium is detected, measures shall be taken, such as preventing leaves, soil, sand, etc. from getting into pools, as needed.

approximately 1Bq/L, which is substantially lower than the control target value of 10Bq/L for tap water. However, the value varies slightly with each measurement, depending on the measurement conditions (measurement instrument used, background value at the time of measurement, etc.). * No.7 Nihonmatsu Municipal Obama Junior High School was resurveyed.
