High Concentration Of Radioactive Cesium Found In Land Animals 40 Km From Fukushima Nuke Plant

High concentration of radioactive cesium found in land animals (Kyodo News, March 2, 2013):

A high concentration of radioactive cesium has been found in a range of land animals and insects in areas around the site of the Fukushima nuclear plant accident, providing a clue to a mechanism of radioactivity accumulation in the food chain, a study showed Saturday.

According to a survey by the Tokyo University of Agriculture and Technology and Hokkaido University, over 6,700 becquerels per kilogram of cesium 137 was detected in a frog captured in Nihonmatsu, Fukushima Prefecture, some 40 kilometers west of the crippled nuclear plant.

The finding suggests animals positioned relatively high in the food chain tend to accumulate more radioactive materials, the research team said.
