TO CORRECTLY UNDERSTAND RADIATION
[Excerpts]
For those in the teaching environment

Zones exceeding 3.8mSv/h [N.B. The PowerPoint says "Zones below 3.8mSv/h"]
- The chances are slim but there might places such as puddles of water, sand boxes, trees and grass, and building rooftops where radioactive substance may have accumulated. There is a possibility that if one’s hands come into contact with that, and then one eats with one’s hand, radioactive substance could be ingested into the body. Remind your children to wash their hands and gargle just in case.
Depending on the radiation level, limit the amount of time playing outdoors and in school grounds.
- When determining activities at school or outdoors, implement [these actions] based on information from the national government and instruction from the Board of Education.

- For “definitive impact” there is a “threshold” below which there is absolutely no damage found. For example, temporary decline in white blood cells will be seen [only] above the threshold level of 250mSv.
- However, there will be no impact with such weak radiation levels such as [cumulative] 250mSv (=250,000microSv) over several years. Therefore, it is unimaginable that physical damage from “definitive impact” could occur at the level of radiation seen outside of the evacuation zone.

- It is unthinkable under current conditions that residents, even those staying near the nuclear power plants, would be exposed to a cumulative total of 100mSv (=100,000μSv) of radiation. The amount of radiation, however, should be monitored. At below the cumulative level of 100mSv (=100,000μSv), the probability of cancer due to other causes could become higher, and no clear correlation has been seen between radiation and increase in the probability of cancer.
it makes me angry to see lies like this being fed to innocent people:
“and no clear correlation has been seen between radiation and increase in the probability of cancer.”
actually, the whole fukushima incident is very sad.
curious why you’re showing the picture of the fukushima complex before the reactor buildings were exploded at the top of your blog? is this part of the efforts to whitewash the whole disaster “to protect japanese society and morality”?
Hi, Clinton. Regarding the Fukushima photo in the blog header, we unfortunately have a technical problem that keeps some of us from uploading images to the site, so that is simply the same image we started with, which was one of the few available to us at the time. If you read a bit more of the blog and Green Action’s mission, I think it will be clear that none of us are trying to whitewash anything about this disaster.
To help counter the propaganda distributed to schools in Japan by the Nuclear Industrial Complex of Japan (NICJ) this Japanese website was made: http://nuketext.org
Prior to the disaster at Fukushima it was averaging 30,000 hits per month. In March it received more that 1.2 million hits! It includes a site suitable for children: http://nuketext.org/indexkids.html
