How much of the Cesium found in vegetables is simply leftover from Chernobyl?
Berkeley nuclear engineering team:
I was wondering if you had an estimate about how much of the Cesium-137 you have detected in leafy greens, mushrooms, grass, etc might be left-over from Chernobyl?
Also, does anybody have an estimate of the Cesium fallout over California from Chernobyl?
claims that the amount of Cs-137 fallout over Washington state from Chernobyl was significantly higher (at 300 Bq/m2) than what can be inferred from the data published here (50 Bq/m2).
