Radiation in Milk from Eastcoast

We live in Philadelphia with two young children (a toddler and a preschooler). It has rained and flooded so much in the past a few months on the eastcoast. We are wondering how much cesium is in the food chain here, especially milk. We used to live in Foster City, CA. So I know it does not rain much from March to October in the Bay Area.

Does the rain bring more radiation down to the ground than dry deposition? If so, we must have more cesium in our milk through bio-concentration.

Besides, Philadelphia has excessive Iodine-131 in its drinking water. A mystery no one can understand so far...

Wish there is a group of admiring scientists like you around us. WE ARE IN THE DARK AND HELPLESS.

Can we fedex some of our milk to you for testing?
