Jaysus, as if we didn't have enough to worry about over imports and toxic things in our food. Now, you can eat healthy.. grow your own foods and when you go to grate something for your salad, dump radioactive carrots into the bowl.
Now, I am no fan of Chinese imports (at least the ones designed by American get-rich-quick companies) and have expressed concern over items like a child's toy ray gun with a REAL LASER in it being sold around here.
That being said, I own a radiation meter I purchased back when the DU release was a news story here in Hawaii and I just ran a quick survey of the kitchen, which does include many metal items form China.
Yes, I did detect some elevated levels of radiation, but nothing I would consider a serious problem. Normal background on this meter is between 8 and 11 (we live on basaltic rock). The highest level I got was a 34 and that was off the metal cover on the Bic disposable lighters. Some of the made in China metal ware got 14-17. A lot of it, including the grater, did not show detectable levels above background.
Now, with more sophisticated detectors and shielding from the outside there may be detectable levels of radiation but just to put things in perspective the high speed lens on my night vision scope (my own assembly, NVS you purchase at stores do not have this) is made from Thorium glass, a beta source, and puts the radiation meter into the hundreds.
So unless someone else with radiation equipment gets a different result, I don;t think this is the issue the poster is trying to make it.
