High Stress Found in Japanese Nuclear Plant Workers

They must have heard about those moths.

Months after the meltdown at Japan's Fukushima Daiichi nuclear power plant, workers there and at a nearby plant that remained intact were still suffering high rates of stress and depression, according to a new study that points to multiple sources of trauma.

Out of close to 900 full-time workers from the Fukushima Daiichi power plant, almost half reported psychological distress, including nervousness, hopelessness and depression, two to three months after the March 2011 earthquake and tsunami that damaged the plant.

Just under one-third of Daiichi workers had symptoms of post-traumatic stress disorder, or PTSD.
