Tepco reports that a greenling (pictured left) caught on August 1 within 20 kilometers of Daichi tested the highest to date for Cesium contamination. Just how high? The fish clocked in at a whopping 25,800 becquerels per kilogram for combined cesium 134 and cesium 137, compared to the previous high of 18,700 becquerels per kilogram found in a cherry salmon.
To put into perspective how high this level of radioactivity is, tea leaves shipped out of Japan have a cap of 500 becquerels per kilogram of cesium. Any higher than that and it is not fit for export, and presumably, not suitable for consumption within the country either.
