From the article:
“If you burn firewood with 468 becquerels/kg of radioactive cesium, it will result in ashes with 85,176 becquerels/kg of radioactive cesium (468 x 182). Even by the lax “standard” of the Ministry of the Environment, you wouldn’t be able to bury these ashes in a regular dump, not to mention using it in your garden. You certainly wouldn’t want to use them in your noodles, because the transfer rate from the ashes to the noodles seems rather high from the example in the article.”
– #Radioactive Okinawa Noodles and Pizzas from Radioactive Ashes from Radioactive Firewood from Fukushima (EX-SKF, Feb. 7, 2012):
Radiation’s reach is indeed long. Okinawa is as far away as you can get in Japan from Fukushima I Nuclear Power Plant, and there has hardly been any radioactive fallout. Maybe because of that, businesses in Okinawa don’t seem to be much concerned about radioactive contamination in goods.
Here’s an example of some Okinawa restaurants having bought firewood from (of all places) Fukushima Prefecture via a distributor in Gifu Prefecture who clearly thought it could get away with it; one of the restaurants made the traditional “Okinawa Soba (noodle)” using the ashes from the radioactive firewood, and has already served the noodles to the customers.
As usual, the familiar refrain from the government officials: “There is no effect on health.” They might as well add “Just keep on smiling.”
From Okinawa Times (2/8/2012):
県 は７日、福島県産のまきを本島内の４飲食店がすでに使用し、うち１店舗では未使用のまきからは最大で、国の指標値４０ベクレル（１キログラム当たり）の約 １１倍に当たる４６８ベクレルの放射性セシウムを検出したと発表した。別の店では、使用後の灰からも最大で指標値８０００ベクレルの約５倍に当たる３万 ９９６０ベクレルを検出。県は「消費者、従業員とも健康に影響が出る量ではない」としている。
Okinawa Prefecture announced on February 7 that 4 restaurants in Okinawa have used firewood from Fukushima Prefecture, and in one of the restaurant the maximum 468 becquerels/kg of radioactive cesium was detected from the firewood, which is about 11 times the level of the national safety limit for radioactive cesium in firewood (40 becquerels/kg). In another restaurant, 39,960 becquerels/kg of radioactive cesium was detected from the ashes after the firewood was burned, which is about 5 times the level of the national safety limit of 8,000 becquerels/kg. The Okinawa prefectural government says, “For both the consumers and the employees at these restaurants, there is no effect on health at these levels.”
