Why would spinach have more than arugula and kale?

I thought Kale and salad was

I thought Kale and salad was also not good according to the article of the French warning pregnant women from fallout in France.

Re:Why would spinach have more (I-131/Cs)than arugula and kale?

If I'm not mistaken, this is a question concerning foods that may harbor I-131 and Cs-137/Ru/Co spinach is in the same family as mustard greens (and tend to accumulate Iodine and I-137,Calcium/Cs-137 if present) while kale and arugula as are butter lettuce, lettuces in general, cabbage, brussels sprouts, broccoli and cauliflower are in the brassica family and our known to uptake potassium vs. Iodine/Calcium/Cs-137, they also have a goitrogenic effect if consumed in great quanitities over time (ie: 6 months or more of constant eating with no consumption of other vegetables)since they have iodine/I-131 (uptake to thyroid) blocking properties and may even prevent absorption and utilization of Calcium to bone structure.
