Dear Collegue,

The contamination is coming probably from interception after dry and wet 
deposition (mainly dry, in the doserate tables generally no rain was 
mentioned), the spinach have relative large leafs, it retains quite well 
a fallout type contamination, washing is a very good coutermeasure.
