"(AP) NEW YORK - A map of radioactive contamination across Japan from the Fukushima power plant disaster confirms high levels in eastern and northeastern areas but finds much lower levels in the western part of the country, thanks to mountain ranges, researchers say
The mountains sheltered northwestern and western parts of Japan as radioactive cesium-137 emerged from the power plant and blew downwind, the scientists said.
Cesium-137 is just one of the radioactive materials that came out of the plant, but researchers focused on that because it's particularly worrisome. It lasts for decades in soils, emitting radiation and potentially contaminating crops and other agricultural products."
