The following question was answered by an expert in the appropriate field:


I'm thinking of buying a clay pot from Iga in Japan ( but am worried about radiation effects from Fukushima. What is your assessment?


With respect to pottery from the Iga region, that region of Japan is about 560 km southwest of Fukushima. That area was not greatly impacted by the atmospheric releases during the Fukushima accident, so clay from Iga would not contain any fallout residue that would be a public health concern. By now, six years on, most of the fallout is gone due to natural radioactive decay and weathering. In addition, testing is done on many products exported from Japan to the United States. You could inquire if Toiro Kitchen's products have been tested.

For these reasons, I would not be worried about these clay pots. I hope this allays your concerns.
