Oct. 20 — “Residents in the town’s district of Watari also found their Geiger counters going off their scales, which go up to 10 microsieverts per hour”, said Kanna Mitsuta, a Friends of the Earth researcher who participated in a Sept. 14 radiation survey in Fukushima City, 60km from the meltdowns, according to the Deutsche Presse-Agentur.
Can it be ‘Decontaminated’?
Tomoya Yamauchi, professor and radiation expert at Kobe University, said the contamination in the area is so severe that authorities need to remove not only the topsoil but also road surfaces, roofs and concrete walls, reports the DPA.
Mitsuta is concerned that the decontamination effects are only temporary, “Radiation levels drop soon after decontamination work, but whenever it rains, contaminated soil flows into the area from surrounding mountain forests and the levels climb once again.”
What about the reactor that is still releasing radioactive steam? Might that also be why decontamination is not going as planned? From Oct. 18 & 19:
