Oct. 23 — According to Kyodo, the “Kashiwa hot spot [is] linked to Fukushima” and Japan’s Science Ministry “reverses government claims after [an] on-site survey finds high amounts of cesium.”
When the local government received a report about the 57.7 microsieverts per hour measurement at the site, it said the radiation was unlikely to be related to the Fukushima disaster.
However, “On Sunday, the science ministry and the city government [...] said it is highly likely that rain tainted with fallout from the Fukushima plant was running into nearby soil,” reports Kyodo.
“The ministry has confirmed that rain water is leaching out of the ditch and into the soil at the spot, ministry officials said at a new conference Sunday,” the article notes.
