Fresh catch - A fish caught near the Fukushima plant contains very very high levels of Cesium

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.


  1. Personal Protective Equipment is used as barriers between a person and a hazard. Their main purpose is to prevent injuries by protecting people from unnecessary exposure to hazards on the job.

  2. Ok so radiation dose reduced but using serial USS or physical exams wouldnt reduce neg appy rate? Radiation badge
    already saying its about 10% with USS, repeating this wouldnt help?
    I guess what I am saying is radiation risk is sorta an unknown. is there someway we can reduce this risk until we know more about it?
