• 放射線による慢性的な障害は、ふくしまの件では微々たるものなのでは？
• 大気汚染、喫煙、飲酒による健康への障害の方が遙かに大きい。
• 問題は、放射線への知識が貧弱すぎること(いわゆる文系馬鹿のマスコミが煽る)と、放射線を積極的に回避しづらいことである。
• 例えば、大気汚染は外出を控えることで避けられるし、喫煙は吸わないこと、副流煙を吸わないことで回避できる。飲酒は飲まなければよい。
• しかし、放射線からは距離を置く、放射性同位体を含む物を摂取しないことしか回避できない。
• しかも、どれだけ体内被曝することで、どれだけ生命予後に影響を及ぼすかは不明である。
• 政府が基準値を定めているが、その値は次々と変更され、疑心暗鬼を生じる原因となってしまった。
