I don’t remember the source, but I have heard that this kind of radiation disappears in months, as opposed to Chernobyl, which will stay bad for a long time.
More informed people may correct me.
I’m no expert but I read early on that the half life for this Cesium 131 is 8 days and its totally gone in 80 days. I just hope its true. right now we are just taking a common sense precaution and we are drinking bottled water and have stopped buying fresh cream. We are using a non dairy creamer in our coffee and powdered milk for cooking. As for veggies we are still eating them so who knows?
