Why risk perception is much higher than real risk?

• Radiation is invisible: Smoking is avoidable because it can be seen.

• Radiation is not controllable: Food poisoning by pathogenic E Coli was avoidable by heating meat.

• Children’s issue: Dividing cells may be more sensitive to radiation induced toxicity, theoretically.

• Long lasting: Not 1 year’s problem, but will continue decades.

• Uncertainty: We have only a few evidence of low dose radio-contamination in history.

In 1987 more than 90% of all reindeer meat in Norway was above 600 Bq/kg

Maximum values ‘86/’87Cow milk: 650 Bq/kgGoat milk: 1350 Bq/kgFreshwater fish: 30 000 Bq/kgLamb: 40 000 Bq/kgReindeer: 150 000 Bq/kg Mushrooms: 1-2 MBq/kg

Permitted levels 600 Bq/kg general foodstuffs

Raised permitted levels to 6000 Bq/kg in reindeer (+mushrooms, game, freshwater fish)

森田貴己氏より

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 Citizens distrust government and scientists

• 消費者よりも流通が気にする Market rather than consumers worries about contamination.

• 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 eating fish and supporting 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 )

差別 Discrimination toradioactive contamination

• Discrimination in even the Kyoto traditional 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.
