Fukushina Plutonium At Normal Background Levels
From NHK Japan morning broadcast:
Five locations were tested on the grounds of the Fukushima Dai-ichi nuclear plant. Two samples showed a trace of plutonium 238. This contamination is consistent with global background contamination since Cold War atmospheric nuclear weapons testing. Ingesting 50kg of this soil over a 50 year period would result in a dose of 0.12uSv. The activity level of the contamination is 0.54 Bq/kilo or less than 1/100th that of a single banana.
