No wonder the first trading of rice futures in Osaka fetched 40% premium over the exchange-suggested contract price.
If this number is correct, the harvest season in Japan will be indeed "chaos".
From the tweet of Ryuichi Kino, who has attended and reported on almost all TEPCO/government press conferences regarding the Fukushima accident since March, reporting on the TEPCO/government joint press conference on August 8:
Germany's ZDF Television is here. Said 35,000 becquerels/kg [of radioactive cesium, most likely] has been found in the soil of a rice paddy planted with rice, and asked if the government does any thorough check. Hosono [minister in charge of the nuclear accident] consulted with his staff for a very long time, and said they will confirm the number. He said the government will check the rice as they grow in the rice paddies.
The transfer factor from the soil to rice is considered to be about 0.1. 35,000 becquerels/kg in soil may result in 3,500 becquerels/kg of harvested rice, 7 times the provisional safety limit which is already far too loose for the staple like rice.
I've found the video clip for this part. It's the rice paddy in Fukushima City. Fukushima City was OUTSIDE the evacuation zone of any kind, so the soil was apparently never tested by the prefectural government. The reporter asks the question in English, with a Japanese interpreter.
Japanese people who watched the video or knew about it from Kino's tweets are thanking ZDF for having shown up and asked questions at the press conference. It's been a very long time any foreign media showed any interest in these conferences given by TEPCO/government on Fukushima I Nuke Plant and radiation contamination.
I hope more foreign media (not their Japanese bureaus) will come and ask hard questions.
35,000 becquerels/kg of cesium in soil would translate into 2,275,000 becquerels/square meter (35,000 x 65), which is way above the forced evacuation criterion in the Chernobyl accident (1,480,000 becquerels/square meter).
