These charts compare the measurements taken of iodine and cesium levels in spinach, parsley, and raw milk from Ibaraki last week to those taken on March 30. Levels of iodine and cesium are going down in all cases but one (spinach from Hokota).
Levels of iodine and cesium are still high in spinach and parsley from some parts of the prefecture, but the levels in milk are below the threshold.
Levels at which we need to start getting concerned
iodine (I-131): 2000 Bq/kg for vegetables
cesium (Cs-134, 136, 137): 500 Bq/kg for vegetables
Today’s verdict: Safe to drink milk from Ibaraki, but wait a bit more for the spinach and parsley from Ibaraki
