This is another clearinghouse diary for the posting of additional news (with links to their source) and intelligent commentary about the ongoing nuclear disaster(s) in Japan.
THE JNI coverage is for reporting and analysis of events in Japan following the March 11 Disaster -- the earthquake, tsunami and meltdowns at the Fukushima Nuclear Power Plant. JNI is NOT a place for editorializing or POVs on nuclear power. The ROV does not replace breaking news, but rather serves as homebase for ongoing updates throughout the week.
TEPCO site photo shows greater than 10 Sieverts per hour being measured with a 3-meter-long arm. Picture by gamma ray camera shows two sources of high radiation at the bottom of the exhaust stack for Unit 1 and 2 Reactor Buildings. NHK World - TEPCO to check plant radiation levels carefully The operator of the crippled Fukushima nuclear complex is searching for radioactive hotspots after finding extremely high radiation near an exhaust pipe at the plant. NHK World - Highest radioactivity level detected at nuke plant The operator of the Fukushima Daiichi nuclear power plant says it has detected 10,000 millisieverts of radioactivity per hour at the plant. The level is the highest detected there since the nuclear accident in March. XKCD Radiation Dose Chart (90KB PNG) comparing radiation doses from different sources. EX-SKF blog post with English translations of Japanese articles from Kyodo News and Jiji Tsushin.Fukushima I Nuke Plant: OVER 10 SIEVERTS/HR Radiation OUTSIDE Reactor 1 and 2 After over a month without an update, TEPCO finally published new Radiation Survey Maps 2011, August, 2 - Survey map of Fukushima Daiichi Nuclear Power Station(on August,1) 457KB PDF showing a light yellow balloon that was "Measured at 14:00∼14:30, August 1 2011" U1/2 SGTS The Radiation Survey Map should show a black arrow pointing to the location, but that is missing in the English version. The black arrow can be seen on the Japanese version. 2011, August, 2 - Survey map of Fukushima Daiichi Nuclear Power Station(on August,1) 467KB PDF Comment by Joleau in k9disc diary 10,000 Millisieverts/Hour @ Fukushima 10 Sv is 1,000 Rem. A thousand Rem acute absorbed dose causes gastrointestinal syndrome - the lining of the stomach and intestines is destroyed, violent vomiting and diarrhea ensue within 10 minutes, death in a matter of hours. The TEPCO Live Camera has had the Unit 1/2 Exhaust Stack centered in the frame for the last couple of months. You can see the duct angling down towards the exhaust stack between Unit 1 and 2 Reactor Buildings, just to the left of the green vegetation. Today, it was announced that TEPCO found a 5 Sv/h reading in the Unit 1 Reactor Building on the second floor. NHK World - High radioactivity level at reactor building The operator of the Fukushima Daiichi nuclear power plant says it has detected the highest confirmed indoor level of radioactivity at the facility since the March accident. But that is not all, the Mainichi Daily News reports that TEPCO has found other highly radioactive pipes, but that TEPCO will not measure them. TEPCO claims that no workers will be in that area, so the readings are not needed! In a related development, TEPCO said on Aug. 2 that there were two more pipes nearby that apparently showed radiation in excess of 10 sieverts. The utility said it had not actually measured the radiation there and it had no plans to do so because there would be no one working there. |
