22 March 2012 (Mainichi) – The Fukushima Prefectural Government revealed on March 21 that it deleted five days of early radiation dispersion data almost entirely unread in the wake of the meltdowns at the Fukushima No. 1 nuclear plant. The data from the System for Prediction of Environmental Emergency Dose Information (SPEEDI) — intended to […]
By Charlie Smith 19 March 2012 A Japanese citizen watchdog has reported that cesium-137 levels rose more than five times in Fukushima over a 24-hour period between March 15 and 16. The online Fukushima Diary pointed out that there were no megabecquerels per square kilometre of cesium-137 detected between March 8 and March 11. But […]
グレイは放射線が物質に当たった時のエネルギー量を表し、大気中の放射線量１グレイは１シーベルトに換算できます。 【参考】健康安全研究センターで平常時に観測されていた測定値：１時間あたり0.028～0.079マイクロシーベルト（平均値は概ね、0.035マイクロシーベルト／時）で推移＜上記の緑色の帯の範囲＞。 Machine translation: Grey represents the amount of energy when radiation hits the material, you can convert the atmospheric radiation 1 gray dose of 1 sievert. [Wikipedia: The gray (symbol: Gy) is the SI derived unit of absorbed radiation dose of ionizing radiation (for example, X-rays), and is defined as the absorption of one […]
Fukushima City at EveryTrail By arevamirpal::laprimavera 16 March 2012 Professor Yukio Hayakawa was armed with 4 different radiation survey meters. One of the reasons he went to Fukushima was apparently to test the survey meters and compare the readings. The entire walk took 7 hours yesterday, says Hayakawa in his tweet, nothing compared to mountain […]
We use a Lagrangian particles dispersal method to track where free floating material (fish larvae, algae, phytoplankton, zooplankton…) present in the sea water near the damaged Fukushima Daiichi nuclear power station plant could have gone since the earthquake on March 11th. THIS IS NOT A REPRESENTATION OF THE RADIOACTIVE PLUME CONCENTRATION. Since we do not […]
By Alan Boyle9 March 2012 Satellite images tracked the catastrophic impact of Japan’s magnitude-9.0 earthquake and tsunami on the Fukushima nuclear complex and other key sites, and now they’re tracking the reconstruction. To mark Sunday’s anniversary of the disaster, DigitalGlobe is releasing pictures showing “before, during and after” views of the devastation. You can see […]

About this “black dust” in Minami Soma, see my past posts, here, here, here.Minami Soma City’s Assemblyman Ooyama reports on his blog (3/8/2012): 試料：ID:080 鹿島区ジサ原CCs-134 1,498,000 ± 1,586 Bq/kgCs-137 1,932,900 ± 2,481 Bq/kgTOTAL 3,430,900± 2,945 Bq/kg It seems to be part […]
By Richard Engel, NBC News Chief Foreign Correspondent7 March 2012 It’s what an insurance company might call “a write-off” – a place that seems beyond salvation, and certainly too expensive to fix. I’d never thought of land that way. You smash up a car, and then it’s compacted into a square and maybe even recycled. […]
By William Pesek 6 Mar 2012 A year after an earthquake in Japan touched off the worst nuclear crisis since Chernobyl, here’s the question on my mind: Who’s going to jail? The news media are asking the obvious and safe questions ahead of March 11: How well did the government respond? Whither the devastated northeast? […]
The key to cooling damaged nuclear plants now poses a major radioactive worry and storage challenge. By PHRED DVORAK, with Mitsuru Obe29 February 2012 OKUMA, Japan – Nearly a year after the 11 March 2011 earthquake and tsunami sparked triple meltdowns at reactors here, the taming of Fukushima Daiichi has become in large part a […]
