Cesium from Fukushima plant fell all over Japan, AJW by The Asahi Shimbun, Nov. 26, 2011:
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. [...]
But the Ministry of Education, Culture, Sports, Science and Technology’s survey results released on Nov. 25 showed that fallout from the Fukushima plant has spread across Japan. [...]
The ministry also said Nov. 25 that it will conduct aerial measurements of cesium accumulations in soil in regions outside the 22 prefectures starting next year. That is because small amounts of cesium have been detected in dust deposits in Hokkaido and western Japan.
- Included the cumulative densities of radioactive substances in dust that fell into receptacles from March – June.
- No figures were available for Miyagi and Fukushima prefectures, where the measurement equipment is said to have been not operating.
- Only one measurement station was used for each of the other 45 prefectures.
More to come…
