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

August 2, 2011 Local Nuclear Emergency Response Headquarters (Radioactivity Team) Disaster Provision Main Office of Fukushima Pref. (Nuclear Power Team)

1. Monitoring date Thursday July 21–Wednesday, July 27, 2011

2. Monitored facilities Number of target facilities Number for this report (Those monitored from July 21 to July 27) 220 122 * Although the number of target facilities was initially 76, the number was later changed to 220, as shown in the table, due to requests from nursery facilities, etc. (as of July 19).

3. Monitoring Results Analyses of radioactive nuclides of the water in outdoor swimming pools at schools, etc (1) Radioactive iodine Not detected at all facilities. (2) Radioactive cesium Cs-134 Not detectable～4.66Bq/L Cs-137 Not detectable～5.95Bq/L

4. Handling of monitoring results Also, regarding swimming pools in junior high schools where cesium-134 and cesium 137 was detected, we request that the installation personnel make a judgment on the necessity of restricting the use of the facilities, based on the situation in each area, by referring to the “Use of Outdoor Swimming Pools at Schools in ” (Nuclear Safety Division, Science and Technology Policy Bureau, and School Health Education Division, Sports and Youth Bureau, Ministry of Education, Culture, Sports, Science and Technology, June 16, 2011) and “Notice of Use of Outdoor Swimming Pools at Schools in Fukushima Prefecture” (Chairman, Fukushima Prefectural Board of Education, June 21, 2011,). Also, the form of utilization of the facilities at which cesium-134 and cesium-137 was detected this time is considered to be similar to that of utilization of bathing areas. Therefore, requests will be made to the entities that have established the facilities to make a judgment on the necessity of restricting the use of the facilities, based on the situation in each area, by referring to the indication of water quality provided by the Ministry of the Environment.

（Reference） Indication of water quality regarding radioactive materials in bathing areas considered when making a judgment on the establishment of bathing areas (provisional values for this summer) (*):

・Radioactive cesium (Cs-134 and Cs-137) 50Bq/L ・I-131 30Bq/L * The radioactive cesium that was detected this time is significantly lower than the indicated amount

(*) “Indication of Radioactive Materials in Bathing Areas” (Kansuitai No. 110624001, Notice of the Manager of the Water Environment Management Division, Environmental Management Bureau, Ministry of the Environment, June 24, 2011)
