A Japanese organization called “declaration of safety in Fukushima” (福島 安全 宣言) or something like that launched a campaign for the “decontamination of minds” (心 の 除 染) to convince that radioactivity is safe.
In a video taken in the twenty kilometers zone, sill evacuated, a person takes radiation readings and states that it is safe as it is well below 100 mSv. But the video avoids the most contaminated areas and confuses microsieverts and microsieverts / hour. When the Japanese authorities say there is no risk below 100 mSv, it is on the whole life span. To compare that value to microsieverts per hour or millisieverts per year is meaningless.
There are also videos of pseudo-scientific conferences to affirm that radiation in Fukushima is safe. The audience seems very small.
The group calls for the lifting of the evacuation orders and the return of inhabitants, and also for the restart of the declared safe nuclear reactors.
Another similar initiative, already presented by the Blog of Fukushima, has been to make children to pick up garbage along the highway 6 that passes thru the forbidden zone. This time, it was an organization called “Happy Road Net” which was the organizer. http://happyroad.net/wordpress/wp-content/uploads/2015/09/Image150915145225.pdf
Let us remember that it is internationally recognized that there is no safe limit for radiation and that each radiation dose has an impact that is proportional to it. In such a context, it is recommended that the radiation exposure should be justified by a benefit. What was the benefit for these children?
It’s a safe bet to say that the decontamination of minds will be no more effective than the decontamination of the contaminated territories was …
