A leading Japanese daily says radioactive substances from the Fukushima Number One nuclear power plant are likely to affect the “southern part of the Korean Peninsula.”

The Yomiuri Shimbun said Wednesday that the recent projection came after the Japan Meteorological Agency unveiled on its Web site a diagram that predicted the expansion of radioactive substances.

The diagram was drawn up based on the discharged amount of radioactive substances and the amount of such substances in the air. It showed that the southern part of the Korean Peninsula is expected to see one-1000 trillionth of radioactive substances per square meter, which is similar to levels projected for Osaka. The projection was based on the assumption that one becquerel of radioactive iodine had leaked out from the Fukushima plant.
