=================================================
Tokyo Brown Tabby's latest captioning is over the collection of video clips of three Japanese nuclear researchers, claiming safety for plutonium on the national TV. The first two appeared on TV after the March 11 accident to assure the public that there was nothing to worry about on plutonium, because it was so safe.
Three Plutonium Brothers are:
(1)Tadashi Narabayashi
Professor in Engineering
at Hokkaido University
(in TV Asahi "Sunday Scramble" on Apr. 3, 2011)
(2)Keiichi Nakagawa
Associate Professor in Radiology
The University of Tokyo Hospital
(in Nippon TV "news every" on Mar. 29, 2011)
(3)Hirotada Ohashi
Professor in System Innovation
University of Tokyo
(at a panel discussion in Saga Pref. on Dec. 25, 2005, regarding using MOX fuel at Genkai Nuke Plant)
Transcript of the video. Spread the word, make them accountable:

Well, half of adult males will die if they ingest 200 grams of salt. With only 200 gram. However, oral lethal dose of plutonium-239 is 32g. So, if you compare the toxicity, plutonium, when ingested, is not very different from salt. If you inhale it into your lungs, the lethal dose will be about 10 milligram. This is about the same as potassium cyanide. That sounds scary but the point is plutonium is no different from potassium cyanide. Some toxins like botulism bacillus that causes food
poisoning is much more dangerous. Dioxin is even more dangerous. So, unless you turn plutonium into powder and swallow it into your lungs....
MC: "No one would do that."
Besides, plutonium can be stopped by a single sheet of paper. Plutonium is made into nuclear fuels in facilities with good protective measures, so you don't need to worry.

For example, plutonium will not be absorbed from the skin. Sometimes you ingest it through food, but in that case, most of it will go out in urine or stools. The problem occurs when you inhale it. Inhaling plutonium is said to increase the risk of lung cancer.
MC: "How will that affect our daily lives?"
Nothing.
MC: "Nothing?"
Nothing. To begin with, this material is very heavy. So, unlike iodine, it won't disperse in the air. Workers at the plant MAY be affected. So, I'd caution them to be careful. But I don't think the public should worry. For example, 50 years ago when I was born, the amount of plutonium was 1000 times higher than now.
MC: "Oh, why?"
Because of nuclear testing. So, even if the amount has now increased somewhat, in fact it's still much less than before. However, if it is released into the ocean through exhaust water, that's a problem. Once outside, plutonium hardly decreases.
MC: "It takes 24,000 years before it dicreases to half, doen't it?"
That's right. So, in that sense, plutonium is problematic. But then again, there will be no effect on the public. I think you can rest easy.
MC: "Let me summarize. Plutonium won't be absorbed from the skin. If it's ingested through food, it will go out of the body in urine. If it's inhaled, it may increase the risk of lung cancer. But since it's very heavy, we don't need to worry."

MOX fuel at Genkai Nuke Plant)
MC: Dr. Ohashi, please.
I'd like to point out two things. What happens in a [nuclear] accident depends entirely on your assumptions. If you assume everything would break and all the materials inside the reactor would be completely released into the environment, then we would get all kinds of result. But it's like discussing "what if a giant meteorite hit?" You are talking about the probability of an unlikely event.
You may think it's a big problem if an accident occurs at the reactor, but the nuclear experts do not think Containment Vessels will break. But the anti-nuclear people will say, "How do you know that?" Hydrogen explosions will not occur and I agree, but their argument is "how do you know that?"
So, right now in the safety review, we're assuming every technically possible situation. For example, such and such parts would break, plutonium would be released like this, then it would be stopped here...something like that. We set the hurdle high and still assume even the higher-level radiation would be released and make calculations.
This may be very difficult for you to understand this process, but we do. To figure out how far contamination might spread, we analyze based on our assumption of what could occur. However, the public interpret it as something that will occur. Or the anti-nuclear people take it in a wrong way and think we make such an assumption because it will happen. We can't have an argument with such people.
Another thing is the toxicity of plutonium. The toxicity of plutonium is very much exaggerated. Experts dealing with health damage by plutonium call this situation "social toxicity." In reality, there's nothing frightening about plutonium. If, in an extreme case, terrorists may take plutonium and throw it into a reservoir, which supplies the tap water. Then, will tens of thousands of people die? No, they won't. Not a single one will likely die. Plutonium is insoluble in water and will be
expelled quickly from the body even if it's ingested with water.
So, what Dr. Koide is saying is if we take plutonium particles one by one, cut open your lungs and bury the plutonium particles deep in the lungs, then that many people will die. A pure fantasy that would never happen.
He's basically saying we can't drive a car, we can't ride a train, because we don't know what will happen.
MC: "Thank you very much."

Let's imagine some bad guys have just thrown me into a reservoir. I'm not only hard to dissolve in water, but also hard to be absorbed from the stomach or intestines, and eventually I will be out of the body. So I can't actually kill people.
But it so often happens that bad guys take a small thing and turn it into a big lie to threaten people.

See, we've been duped. Plutonium is not dangerous! We'd better ask these three to drink it up to prove it's not dangerous. Then we will feel safe, won't we? Please doctors, would you do it for us?
