dunno, I'd prefer if they rather demanded (in toothfull, not toothless way) that http://www.telegraph.co.uk/news/worldnews/asia/japan/8416302/Japan-nuclear-crisis-evacuees-turned-away-from-shelters.html" do not turn away refugees, as well as provided accurate information on the nature of radioactive dirt and the procedures for getting the dirt off (aka, shower).rowmag said:Here is the "letter of request": http://www.soumu.go.jp/menu_news/s-news/01kiban08_01000023.html
This looks rather toothless to me, and doesn't look like it amounts to more than a "Let's get it together folks" plea. Also not clear that anybody has taken it seriously. Anybody know of anyone who has actually been silenced by this?
It seems conceivable for me, given the strongly non-uniform distribution of the radioactive dirt, that some refugees may have beta-active dirt on their skin, which would make Geiger counter show very scary dose rate (due to Geiger counter's much higher sensitivity to beta), and which can also lead to dermatitis (due to high localized doses). Instead of trying to quell the opposition, the government must explain the situation. But they claim there are no immediate effects whatsoever. Which may not be true, as small highly active particles on the skin can give beta rash

even if the average dose is small. That was the case in Chernobyl aftermatch. (ignore the 'after the blast' stuff there, it's for nuclear weapons not for nuclear power plants, different isotope ratios)
Furthermore, beta particles are particularly dangerous to the eye lens. The point is, there is a definite potential for localized acute effects at low 'average' doses, and denying it is highly counter productive and causes the fear if the localized acute effects are first identified by the public before official statement is made.
The 'dirt' nature of contamination (as opposed to 'contagion') must be explained.
Public doses can be decreased a lot if public is informed to wash off the dirt, as well as the nature of radioactivity would be de-mystified and the act of washing would have positive placebo effect. The doses are very dependent to what you're doing.
