Studies shed new light on radiation from Fukushima, finding the whole prefecture highly contaminated.

Two new studies have found that radiation levels in the soil in parts of eastern and north-eastern Japan exceed levels considered safe for farming, while contamination from the stricken Fukushima nuclear plant is much lower in the western part of the country, thanks to mountain ranges. In the first study, scientists said mountains sheltered north-western and western parts of Japan as caesium-137 emerged from the Fukushima Dai-Ichi plant 225km north-east of Tokyo, which was damaged in the March 11 earthquake and tsunami disaster, and blew downwind. Caesium-137 is just one of the radioactive materials that came out of the plant, but is particularly worrisome as it lasts for decades in soils, emitting radiation and potentially contaminating crops and other agricultural products. In a second report, a separate group of scientists investigated levels of radioactive caesium, iod...
