Below is a letter my sister received from here former employer, a professor and specialist on chemical weapons and toxins
Hi Corina:
Nagoya is pretty far from Fukushima so I would not worry too much. The First Fukushima Atomic Power Station is right on the beach so any radioactive heavy metals floating in the air tend to blown to the Pacific. The most of wind is from the west to the east. Of course due to local geography some wind blow from the east to the west or to the west or to the south west. Kaz's relative in Kochi asked me today what they should do. Well there is not much can do for the radioactive materials as they flow in the air and keep emitting alpha and gamma rays. I think beta ray is weak so will not worry too much. One should not inhale the radioactive contaminated air because these heavy metals tend to stay in the lung when you inhale. The radioactive iodine is dangerous because will bind to thyroid gland. You can prevent that by taking nonradioactive potassium iodide.When the nonradioactive iodine occupies the thyroid gland then the radioactive iodine is hard to go to the thyroid gland.Another dangerous radioactive floating in the air is strontium that is similar to calcium so it will go to your bones and teeth.
You brother should monitor the radioactivity of the in Nagoya often.If it becomes high then he should leave.I don't think it is to the stage yet.
It is obvious uranium 235 rod is melt already because of lack of cooling water. But the reaction vessel is made very strong and walled by stainless steel. If the reaction chamber's wall does not melt then it is slightly better. Of course the failed atomic chamber are spewing radioactive metals. But if the chamber's steel wall is melt then it will become like Chernobyl that is total disaster. At the moment the Fukushima's reaction chamber is melt within the chamber's wall so it is partial melt and not a total melting yet. It is somewhat similar to Three mile US atomic disaster. In this case the chamber's wall did not melt so the radioactive spill out was not too disastrous.
Tokyo Kagakudoji asked me to write the article about the atomic power station and the danger of radioactivity so I sent it today. It will appear in the May issue of Chemistry Today. The May issue will come out on April 15.I am interested in almost anything about poison and toxic substances. Tokyo Kgakudopujin's editor said there are only 2 persons in Japan who can answer anything about poisons immediately. He said one is me. So they always asked me at the last moment when some poison case happened.
