Researchers in Japan have discovered that snow on mountains near the Fukushima Daiichi nuclear plant are contaminated with cesium.

Meteorology students from Fukushima University took 31 samples of snow.  14 samples showed high levels of cesium.  The average level of contamination exceeds the safe limit of 200 becquerels per kilogram of radioactive cesium.  One sample, taken at 1,300 meters (4,265 feet) has 3000 becquerels of cesium.

Fukushima University Vice-President Watanabe Akira says the research shows that large amounts of cesium is spewing into the air.
