Dose levels
It is already evident that rapid evacuation and careful screening protected Fukushima's citizens from harm, says Wolfgang Weiss, a physicist at Germany's Federal Office for Radiation Protection in Munich and chair of UNSCEAR. Early and informal analyses by his colleagues suggest that no members of the public received a dangerous dose of radiation.
That finding is supported by a sweeping public-health study begun last summer at Fukushima Medical University. With a ¥78.2-billion (US$958-million) budget, the survey is designed to monitor the health of some 2 million people from the region for 30 years. According to the latest estimates, released on 20 February, 99.3% of 9,747 people living in towns or villages close to the plant received less than 10 millisieverts (mSv) in accumulated effective dose in the first four months after the accident. The highest recorded dose was 23 mSv, well below the acute 100-mSv exposure levels linked to a slight increase in cancer risk.
Yet suspicion is hampering the ambitious health survey, which hopes to nail down the long-term impact of Fukushima on ordinary citizens. Despite efforts to promote the study among evacuees, participation stands at just 21%. Most of the people I've met here refuse to fill in the questionnaires. They don't see credibility in what the government does, and they say, 'this is just a survey of guinea pigs', says Shizuko Otake of the non-profit organization Shalom, which supports refugees in neighbouring Minamisoma and Iitate.

So it's probably better to say that there's a
lack of credible evidence demonstrating that someone
did receive a dangerous dose, rather than claiming that they know that
nobody did.
