They will power-wash the trees and call it "decontamination".
At least in this video, they put down the tarp under the tree.
NHK News on 11/28/2011 has a clip that shows exactly the same "decon" method but without any tarp to at least shield the soil from radioactive materials being sprayed down.
This "advanced technology decontamination" as per Minister Hosono will be used by 600 fruit orchards (2200 hectares) in 3 municipalities in Fukushima (Date City, Kunimi-machi, Koori-machi) starting in the middle of December. And the fruit farmers themselves will get to do the decon job.
NHK News also has this from the head of the JA in Date City:
"I know it will be a heavy burden on the fruit farmers, but in order to deliver safe fruits to consumers we need to do decontamination as soon as possible. We want to finish it as soon as possible."
Ummm. No thank you. And what is the point of power-washing the radioactive materials off the trees into the ground so that the roots can absorb?
Has Fukushima Prefecture done any study to show that this power-washing method is effective?
