I shared this chart a long time ago in the last "radiation" thread here on TeaChat that eventually deteriorated into a "morass" and was locked and deleted. Just one of many pieces of research from my studies when I was taking my college students to Japan in 2011 as well as my wife and in also in 2011.
The Sue family who produce Somayaki items for our site are still unable to return to their home village of Namie.Therefore, Mr. Sue has started the process of setting up his own kiln in the city of NihonMatsu(in the middle of Fukushima prefecture). As his staff are scattered around the country and there is no clear date for their return, the kiln's output cannot return to its former level. However, Mr.Sue has indicated that he would be able to fulfill some small orders with the help of neighboring kilns. The good news is that despite a decrease in production and long waiting times,Somayaki is once again being created. If you have any requests for particular items please let me know and I will pass them on to the craftsman in the hope that we can meet your needs however long it takes. Thank you for continuing to support Somayaki.
It is with deep regret that we have to inform you that production of Somayaki is currently at a standstill. As you may be aware, the earthquake and tsunami which hit the Eastern coast of Japan on March 11, caused considerable damage to certain parts of Fukushima prefecture.
Namie village, where the production of Somayaki is based, was doubly hit, both by the earthquake and by the accident at the neighboring Fukushima Dai ichi nuclear power plant. Being within a 20 km radius of the plant, all the villagers have been forcibly evacuated out of the area.
We were deeply concerned about the whereabouts of the Sue family who produce Somayaki for our site and were very relieved to get word from them recently that they are safe. Having been on the move for weeks, they are now settled at an evacuation center in the Western part of Fukushima prefecture. However as their kiln was damaged by the quake, and as they have had no indication of when they can return to their hometown, we are unable to predict when Somayaki will be in production again.
Artistic Nippon would like to offer its sincerest condolences to the Sue family and their fellow craftsmen in their current situation. It is our hope that the long and distinguished tradition of Somayaki will not be diminished by the tragedy and will emerge stronger than ever in the near future.
The potters in Mashiko have been told not to fire their wood kilns with the wood from the local area. The trees took up radiation since Mashiko is not all that far from Fukushima and was in the downwind pattern a bit, and the firing ash falling on the wares and forming shizenyu will cause the pieces to be a bit radioactive. Pluss the effluent from the kiln will be contaminated too........ getting it into a more bio-available type in the soil. The process of converting a large volume of wood to a very small volume of ash concentrates the tree's contamination.
Scary...... not because of the HIGH level the pots might have...... but because that is not going away anytime soon for them. And is raising the prioces for firing the kilns.... which was already very expensive.
One expatriot potter (Euan) moved out of Mashiko, and even so had his wood source tested for radiation levels before he'd wood fire again at all.
PS: Old red orange and yellow Fiesta ware is seriously radioactive. The uranium colorant used was also contaminated with Thorium.

I also wonder about this.

I am by far an expert on this, but in my understanding Potassium which is found in very large quantities in Banana's (and in lesser amounts in other foods), has an isotope (same element but slightly different molecular configuration) that is radio active. So when you have a large enough concentration of potassium, you are likely to get some that is of the radioactive isotope as well.
Honestly yes Radiation is scary, and I am by no means suggesting anyone volunteers to stand in a giant version of a microwave or a nuclear reactor and see what happens to them. But the truth is radioactivity is a very natural occurring phenomenon, that humans have managed to capture its capabilities by concentrating it into amounts that can be used for both good and bad, (relatively safe and affordable energy, and devastating weapons). It is more so its use in weapons and the realization that the effects of the weapons extend much further than the actual explosion itself that has lead to such a scary picture of radiation. But the truth is, from everything that has been shown by scientific studies you need to be exposed to a massive amount of radiation for there to be any measurable increase in the chance of cancer.
Honestly, and I do not mean to be morbid, but given the fact of exactly what cancer is, the truth is that if you live long enough you will likely acquire it. Sometimes your body can deal with it before it is anywhere close to an issue, other times it needs drastic medical attention. But the truth when you realize cancer is an error in the replication of cells, and how often cells replicate in an average humans body, when taking into account the law of large numbers (given enough chances anything is likely to happen at least once), cancer will happen in anyone that lives long enough, and can be hard to link directly to an item such as radiation exposure.
