The Tokyo Shimbun has begun printing a series of helicopter surveys of concentrations of Cesium 134 and Cesium 137 in the prefectures of the Kanto Plain. Unsurprisingly, they have shown for the most part that the highest readings are found along the spines of the mountains, where the earth touches the upper atmosphere and where rainfall was the heaviest in the days following the explosions of the Fukushima Daiichi reactors.
They have not printed the images for Kanagawa, Tochigi, Ibaraki and Tokyo. I expect them to appear over the next few days.
The dark, almost burgundy spot in the Oku Musashi corner of Saitama Prefecture adjoining the tip of the Tokyo Metropolitan District pretty much guarantees that like my longtime dream of climbing Kumotoriyama, the highest mountain (2017 meters) of the TMD, will be a much hotter trip than it would have been before.
I cannot wait for boot decontaminators to hit the electronics stores or to see signs posted at train stations, "Hikers! Please thoroughly wash your boots before entering the train cars!"
