[1O12] Poverty of politics and lack of the scientific literacy produced FUKUSHIMA

Ignorance of new effective decontamination technique and unnecessary new standards for acceptable limits for radioactivity in food

Six and a half years has passed since the East Japan great earthquake disaster, but people has not return back to their hometown. In addition, the market price of food from Fukushima is not restored. For the decontamination, the transcendence glass technique was developed and clarified to be effective. One can easily decontaminate the ground by spraying the solution on soil there, and tearing off the resulted solidification layer. If the technique is used in an early stage after the NPP accident, inhabitants can operate it and cesium sedimentation into the ground will be stopped. It results in less amount of disposal soil. The other problem on food produced in Fukushaima comes from the world's severest standard for acceptable limits for radioactivity in food. The internal exposure doses of people were evaluated to be 0.019mSv a year in maximum by taking accounts of food sold at the market even in autumn of 2011. It means that the temporary standards was enough to satisfy the target dose rate.
