Why risk percep,on is much higher than real risk?
•  Radia,on is invisible: Smoking is avoidable because it can be seen. •  Radia,on is not controllable: Food poisoning by pathogenic E Coli was avoidable by hea,ng meat. •  Children’s issue: Dividing cells may be more sensi,ve to radia,on induced toxicity, theore,cally. •  Long las,ng: Not 1 year’s problem, but will con,nue decades. •  Uncertainty: We have only a few evidence of low dose radio-­‐contamina,on in history.

論点
•  実際の被曝リスクはバナナのK-­‐40、魚の水銀と比べ
て十分低い（が0でない） Actual risk level is much smaller than K-­‐40 in banana and mercury in fish •  政府と科学者が市民に信頼されていない Ci:zens distrust government and scien:sts •  消費者よりも流通が気にする Market rather than consumers worries about contamina:on. •  双方の「選択の自由」を尊重する Respect both sides of freedom of choice •  食べる利益も説明する（魚、被災地） Explain risk and benefit of ea:ng fish and suppor:ng Fukushima. A home delivery company大地を守る会 sells BOTH less contaminated foods and foods from Fukushima
One reason why we conserve nature is rebuilding linkage between producers and consumers(鬼頭秀一)

•  Discrimina:on in even the Kyoto tradi:onal religious events •  Pine woods with prayers’ message, almost no contaminated, were rejected to be burn in Kyoto religious event (August 16, 2011) •  Garage sales of agriculture/fisheries products of Fukushima in Fukuoka was cancelled. h]p://www.asahi.com/na:onal/update/0925/TKY201109250289.html
