Fukushima Fish Still Radioactive

Fukushima's fish are still being exposed to radioactive cesium, but a scientist thinks they're safe to eat.

More than a year and a half after an earthquake and tsunami destroyed the Fukushima Dai-ichi nuclear power plant in Japan, many fish in the area contain levels of radioactive cesium that are just as high as they were soon after the disaster.

The finding suggests that the region's coastal-dwelling fish are still being exposed to new sources of cesium, possibly from the seafloor or from contaminated groundwater that's flowing into the ocean. And even though most fish sampled in the new study had levels of cesium below safe limits for consumption, some fish contained surprisingly large amounts.
