Cs-137 Cs-134 K-40 Concentrations in real meal in Fukushima (Coop Fukushima) http://www.fukushima.coop/kagezen/2012.html Actual internal exposure level: 1/40 of 1mSv/yr Much smaller than natural exposure level.

Comparison of regulatory limits for fishery products *This index includes S-35, Co-60, Sr-89, Ru-103, Ce- 144, Ir-192 Takami Morita Cs 134 + Cs 137 (Bq/kg-wet) Codex1000 * Japan500 → 100 USA1200 EU1250 Thai500 Singapore500 South Korea370 Hong Kong1000 Chinese Taipei370 Philippines1000 Vietnam1000 Malaysia1000 China800 Prefecture Production value in 2010 (billion yen) Restricted distribution Hokkaido (Pacific side) 4.68- Aomori (Pacific side) 0.862012.8.27~10.31 Iwate1.04 2012.5.2~ 2013.1.17 (some areas) Miyagi2.122012.5.2~2013.1.17 Fukushima0.29After accident ~ Ibaragi0.042012.11.9~ Restricted distribution of cod

→Game fishing must release in Nikko, 150km far from F1NPP ↘Inland fish is still contaminated. ↓Rivers and lakes where 134/137 Cs conc. > 100Bq/kg 6 下野新聞 2013.3.29 朝日新聞 2011.5.29 Jpn daceMasu trout Pond smelt Char, Masu trout Contamination in inland fish

7 Char, Masu trout Radioactive Cs Contamination in inland fish Fukushima Miyagi Tochigi, Ibaraki, Gumma Concentration of Cs-134 & Cs-137 (Bq/kg) Radioactive Cesium concentration of char and masu trout in rivers of Tochigi, Ibaraki, Gumma Prefectures. Broken Lines mean the 100Bq/kg standard Shoichi Yamamoto 2013, FRA

Key Points Actual risk of radioactive Cs is much smaller than K-40 in bananas and mercury in fish Citizens distrust the government and scientists Distribution restriction discourages farmers/fishers Respect both sides of freedom of choice – A home delivery company 大地を守る会 sells (and labels) BOTH less contaminated foods and foods from Fukushima Explain risk and benefit of eating fish and supporting Fukushima.
