"Radioactive substances from the crippled Fukushima No. 1 nuclear power plant have now been confirmed in all prefectures, including Uruma, Okinawa Prefecture, about 1,700 kilometers from the plant, according to the science ministry."
"The ministry said it concluded the radioactive substances came from the stricken nuclear plant because, in all cases, they contained cesium-134, which has short half-life of two years.
Before the March 11 Great East Japan Earthquake, radioactive substance were barely detectable in most areas."
Hiroshi Ishizuka reports for the Asahi Shimbun November 26, 2011.
