Cesium fallout widespread in Japan

Radioactive cesium from the crippled Fukushima No. 1 nuclear plant may have reached as far as Hokkaido, Shikoku and the Chugoku region in the west, according to a recent simulation by an international research team.

Large areas of eastern and northeastern Japan were likely contaminated by the plant, with concentrations of cesium-137 exceeding 1,000 becquerels per kilogram of soil in some places, says the study, which was posted Monday on the website of the National Academy of Sciences.

Researchers for the U.S.-based organization said the study, which was based on partial data readings, is the first to estimate potential cesium contamination across the country. But they also played down the incident’s impact on the three distant regions.

The science ministry’s latest aerial monitoring over Chiba and Saitama prefectures in September confirmed that radioactive cesium released from the Fukushima No. 1 power plant has contaminated parts of the Kanto region.

A ministry report released Thursday revealed that contamination was found in northern Chiba, including the cities of Kashiwa, Matsudo and Abiko, and in the mountainous areas of Chichibu in Saitama Prefecture’s west and Misato in the prefecture’s east.

The highest contaminated areas contained between 60,000 to 100,000 becquerels of cesium-134 and -137 per square meter, it showed. Cesium-134 has a half-life of two years and the one for -137 is 30 years.
