People in Chiba prefecture (200 km south of Fukushima) might take some comfort from knowing that TEPCO dumped “only” 20,000 Bq/m^2 on the local rice farms. But there remains the theoretical possibility that one atom of cesium in my muscle tissue is enough to trigger the growth of a malignant tumor. As a stakeholder in this issue, whose input is so valued by the IAEA, I might want to say that I have zero tolerance for having to live with an “acceptable” level of these fission products in my neighborhood.
What a relief. After all, it’s only the freshwater supply!
