I have noticed some comments here about Fukushima and I thought it might be useful to have one post to capture that conversation. So please, have forth here.
I live in the middle of Canada. Fukushima is on the other side of the world. The only information I have about what goes on there is what I get via the media. And therein lies a problem. Basically, who do you trust?
- There are the mainstream media who are liable to print almost anything.
- There are TEPCO, General Electric and the Japanese government.
- There are regulatory agencies NISA, JAEA, IAEA etc.
- There are a range of items from anti-nuclear activists and pro-nuclear industry lobbyists who post news with their slant.
- There are several quasi-scientific organizations who have posted on the subject. I’m thinking of The Bulletin of Atomic Scientists, the Wiki encyclopediaists and such.
- There are several scientists who have published peer reviewed papers. (see List below)
[Complicating this matter, I regularly see news items stating that the company and/or the government are engaged in cover-ups.]
Originally I was going to write a “What Do We Know” section with information I pulled from old AWOGWN issues, but then I asked myself…
What do we want to know?
- How long until the four Fukushima plants can be completely decommisioned?
- How far has the melted nuclear material [corium] penetrated into the base concrete or into the earth?
- What are the health effects on the local and the non-local populations?
- What is the danger of low level radiactive material bio-accumulating in the human food chain?
- When can the Fukushima prefecture people go home?
- What precisely is the source of the elevated radioactive material in the ocean nearby?
- What is the danger of radioactive fish in other parts of the Pacific?
Which simplified my task considerably, because as far as I know the answers are…
- Unknown.
- Unknown.
- Uncertain [likely will only be revealed in decades].
- Uncertain.
- Unknown [see #1].
- Leaking reactors bathed by sea water [despite what TEPCO says].
- Uncertain.
Those “Uncertains” mean that ongoing monitoring will be required.
Okay, over to you. What’s missing? What’s wrong?
