Cesium-137 in soil 40 km NW of Fukushima Daiichi more than highest levels found at Chernobyl
Concerns about radiation in Japan have now spread to areas surrounding the Fukushima Daiichi nuclear power plant. The levels have been so high to suggest that people in the area should be evacuated. On Wednesday 22nd of March the Japanese science ministry began to report measurements of cesium-137 in upland soil around the plant.
The levels are highest from two points northeast of the plant, ranging from 8690 becquerels/kilogram to a high of 163,000 Bq/kg measured on 20 March from a point in Iitate about 40 kilometers northwest of the Fukushima plant.
The hot spot is similar to levels found in some areas affected by the 1986 Chernobyl nuclear reactor accident in the former Soviet Union. Assuming the radiation is no more than 2 centimeters deep, Chen calculates that 163,000 Bq/kg is roughly equivalent to 8 million Bq/m2. The highest cesium-137 levels in some villages near Chernobyl were 5 million Bq/m2.
