Might be worth your while to review the whole article for its health warnings; lots of data in there, but here are tidbits:

The risks associated with iodine-131 contamination in Europe are no longer "negligible," according to CRIIRAD, a French research body on radioactivity.
The NGO is advising pregnant women and infants against "risky behaviour," such as consuming fresh milk or vegetables with large leaves.
BACKGROUND
After the radioactive cloud emanating from Japan's stricken Fukushima nuclear power plant reached Europe in late March, CRIIRAD, a French research body on radioactivity, an NGO, said it had detected radioactive iodine-131 in rainwater in south-eastern France. In parallel testing, the French Institute for Radiological Protection and Nuclear Safety (IRSN), the national public institution monitoring nuclear and radiological risks, found iodine 131 in milk.
In normal times, no trace of iodine-131 should be detectable in rainwater or milk.
In response to thousands of inquiries from citizens concerned about fallout from the Fukushima nuclear disaster in Europe, CRIIRAD has compiled an information package on the risks of radioactive iodine-131 contamination in Europe. The document, published on 7 April, advises against consuming rainwater and says vulnerable groups such as children and pregnant or breastfeeding women should avoid consuming vegetables with large leaves, fresh milk and creamy cheese.
Data for the west coast of the United States, which received the Fukushima radioactive fallout 6-10 days before France, reveals that levels of radioactive iodine-131 concentration are 8-10 times higher there, the institute says.
