[…] This study aimed to provide an urgent estimate of the dietary exposure of adult residents recruited from three areas in Japan to cesium 134 (134Cs), cesium 137 (137Cs), and, for comparison, natural potassium 40 (40K) on December 4, 2011. Fifty-three sets of 24-hr food-duplicate samples were collected in Fukushima Prefecture and neighboring regions. The 134Cs, 137Cs, and 40K levels in the samples were measured using a germanium detector. Items in the food-duplicate samples were recorded and analyzed for radiocesium intake. Radiocesium was detected in 25 of 26 samples from Fukushima. The median dietary intake of radiocesium was 4.0 Bq/day (range <0.26–17 Bq/day). […] The estimated dose level of radiocesium was significantly higher in Fukushima than in the Kanto region and western Japan. Stepwise multiple linear regression analyses demonstrated that the intake of fruits and mushrooms produced in Fukushima were significant factors for the dietary intake of 137Cs in the 26 participants from Fukushima.

    These abstracts give a single-minded and incomplete picture of what's really going on, imho.

    This abstract says the Japanese "maximum permissible dose" is 1 mSv/year "based on new Japanese standard limits for radiocesium in foods"

    This means the gov't is allowing ADDITIONAL radiation, per person, per year, in the food, above what people are already being exposed to from Background Radiation.

    And the new standard is for Cesium only.

    But what about the other radioisotopes people are being exposed to in their food, air, water, and in the new higher Background Radiation?

    For example, Strontium, Uranium, Plutonium, etc. are not accounted for in this study.

    If Cesium is there, we know that Plutonium is there from past studies on ratios found with Cesium and Plutonium.

    We also know that radiation can accumulate in the body and stay in the body for years; causing cancers and damaging organs.

    Getting a constant stream of radiation in your diet doesn't allow the body to heal itself from the constant onslaught of radiation.

    Plutonium damages the kidneys, and as it stays in the body for decades, it will irradiate nearby organs. Cesium will settle in the muscles and even the heart. Strontium will settle in the bones…

    So allowing a maximum "permissible" dose or minimum "permissible" dose of radiation in food is a fairy tale.

    As most of you know, No dose of radiation is "safe," and no radiation should be "permissible."

    Jet stream took radiation from Fukushima around the globe and contaminated food and water. Thats the situation.
