VIENNA, Jan. 31, 2012 (Reuters) — The health impact of last year's Fukushima nuclear disaster in Japan appears relatively small thanks partly to prompt evacuations, the chairman of a U.N. scientific body investigating the effects of radiation said on Tuesday.
The fact that some radioactive releases spread over the ocean instead of populated areas also contributed to limiting the consequences, said Wolfgang Weiss of the U.N. Scientific Committee on the effects of Atomic Radiation (UNSCEAR).
"As far as the doses we have seen from the screening of the population ... they are very low," Weiss told Reuters. This was partly "due to the rapid evacuation and this worked very well."
Weiss was speaking on the sidelines of a week-long meeting of 60 international experts in Vienna to assess for the United Nations the radiation exposures and health effects of the world's worst nuclear accident in 25 years.
The March 11 disaster caused by a 9.0 magnitude earthquake and tsunami wrecked the Fukushima plant on the coast north of Tokyo, triggering a radiation crisis and widespread contamination. About 80,000 residents fled a 20-km (12-mile) exclusion zone.
Weiss said Japanese experts attending the meeting had told him that they were not aware of any acute health effects, in contrast to the 1986 Chernobyl disaster in Ukraine.
