Radioactive material threatens farms in Japan

Soil from eastern Fukushima and some neighboring areas has levels of Cesium-137 above safe levels for human consumption, and poses a threat to agriculture in the area.

Researchers from Japan, Norway and the United States examined levels of Cesium-137, because it can last for decades in soils, contaminating crops and threatening agriculture.

Researchers took soil samples from 46 of Japan’s 47 regions. Mountains sheltered the northwestern and western parts of Japan from Cesium-137, and much of the country has levels of Cesium-137 well below the established safe limit for human consumption.
