Mountains protected the western and northwestern parts of Japan from contamination by the radioactive material caesium-137 released from a nuclear power plant following a March 11 earthquake, according to researchers who have mapped the effects of the disaster. Researchers said the levels of the radioactive substance are enough to "severely impair" food production in eastern Fukushima prefecture and affect agriculture in the nearby provinces. Another team of researchers has tied rainfall in the days following the incident to contamination of the soil.
