Newspaper announced that Japanese government decided to broaden out geographical areas of nuclear decontamination. This decision has a lot of meaning. At first area that air dose rate is over 20mSv/year was target of decontamination but new limit is over 1mSv/year, it’s unbelievable number. It’s because even in Osaka where didn’t have any trouble related with terrible earthquake in Tohoku area, air dose rate is over 1mSv/year.
