Soil contamination stemming from the Fukushima No. 1 nuclear plant extends less than half as far from the plant as equivalent contamination from the 1986 Chernobyl accident, it has been learned.
The Education, Culture, Sports, Science and Technology Ministry has announced results of a survey on the distribution of cesium-137 and other radioactive materials in soil following the outbreak of the Fukushima nuclear crisis, and its comparison with figures from Chernobyl.
After the Chernobyl explosion, soil containing over 1,480 kilobecquerels of cesium-137 per square meter was detected in a 30-kilometer radius from the plant, and was further found in a range extending 160 to 250 kilometers north-northeast from the power station.
In comparison, such high levels of cesium-137 were found only in about a 30-kilometer-long swathe extending northwest from the Fukushima No. 1 plant, with the highest concentration found 32.5 kilometers away in the town of Namie.
The ministry, however, has not yet been able to confirm the total land area contaminated with radioactive substances from Fukushima or Chernobyl.
